Tsunami causes cold front in Cebu, Visayas (http://cebudailynews.posterous.com/tsunami-causes-cold-front-in-cebu-visayas)

SATURDAY'S rains were caused by the tail end of the cold front brought by the tsunami that struck Japan the day before, the Philippine Atmospheric Geophysical Astronomical Services Administration (PAG-ASA) Mactan office said.

In their weather advisory, Pagasa Mactan weather analyst Ella Comahig explained that cold fronts form when a cooler air mass moves into a pocket of warmer air. The warmer air interacts with the cooler air mass along the boundary, producing precipitation.

“Cebu will still experience the same weather condition,” Comahig said.

Comahig told Cebu Daily News that waves will stand from 3.7 to 5.0 meters while wind speed is projected to reach 10 to 20 kilometers per hour. Sea conditions will be rough for small vessels, she said.

Thats strike two for PAGASA Mactan Station !:bash:

Could they give us a brief and concise explanation on how tsunami could bring along weather fronts?..parang bago yun ah :nuts:

A point difference in the magnitude means big.. magnitude 7.8 has a big difference from 7.9 quake. They say, about 1000X more energy.

Yep, and an Intensity Scale is different from Magnitude Scale

Magnitude is for the power released by the earthquake. We are currently using the Richter Scale (Magnitude 0-9.5) and the newer Moment Magnitude

Intensity is the measurement of the force of the quake as to people and surroundings. The Modified Mercalli Scale (Intensity I-XII) is widely used but the Philippines is using now the PEIS or the Philippine Earthquake Intensity Scale (Intensity I-IX). A revised version of the Rossi Forel Scale.^^

I do not get the connection between the tsunami and the weather cold front. I think this is erroneous. I believe that the quake has nothing to affect weather conditions. Can the quake shake the sky?

http://earthquake.usgs.gov/earthquakes/dyfi/events/us/c0001xgp/us/index.html

maybe one factor is that Tokyo is mostly built in alluvual deposits of rivers in the Kanto Plain and reclaimed land from Tokyo Bay so shaking is much more amplified

while despite closer to the epicenter, Fukushima, Iwate and Miyagi Prefectures are more of stable bedrock. Tsunami was the most destructive factor on these 3 areas. These 3 prefectures comprise the Sanriku Region which has been a haunt of large earthquakes and Pacific-wide tsunami (800 AD, 1893, 1933)

Similar to this is this mechanism is the Aug.2, 1968 earthquake centered in Casiguran, Aurora at M7.3..
Intensity VIII Casiguran
Intensity VII Manila, Palanan
Intensity VI Quezon City, Baler, Tuguegarao, Appari, Baguo City

Despite distance , Manila had severe shaking especially in the Escolta-Binondo area due to the fact that most of Manila's downtown/CBD are built from alluvial deposits of Pasig River

Interesting fact about the recent Japanese earthquake, it moved Japan eight feet closer to the United States according new GPS coordinates.

The earth's crust is in constant movement through earthquakes (movement of earth's crust). maybe million years from now, Japan will be in the middle of the pacific ocean, and the Philippines might be lost in the map

@boy_muscovado brings up a good point about the bedrock differences, etc... this is where the differences in Richter and Mercalli Scale can be seen.. the tsunami may have inflicted more damage to Sendai than the earthquake itself, imo...

I heard that from the late Raymundo Punongbayan comparing the July 16, 1990 earthquake damage in Manila compared with QC and Makati....QC sits on mostly adobe (of the Guadalupe Plateau) while Manila sits on silt deposits of Pasig River, and Makati had its CBD mostly on filled-up swamps. So If its Intensity VII in Manila, it would be VI in Makati then V or IV in QC.

Liquefaction is also a factor in cities sitting on riverine and alluvial deposits, and even in reclaimed lands and properties. We saw that in Dagupan in July 16, 1990 and in Kobe in Jan. 15, 1995

Hmmmm....but it would be too catastrophic if it happens in a short span of time...hehehehehehe......

I theorize, the Philippine Plate will be squeezed into a long chain of larger islands or one very irregularly shaped mass of land in the bordering Philippine Sea and S.China Sea with on big central system of mountain chains (Sierra Madre connecting to Makiling and Banahaw down to Halcon and the Panay Cordillera and Negros Volcanic Peaks, down to the Mountains of Zamboanga, Misamis and Lanao)...mavbe shaped like Japan with Guam and the N. Marianas closer...:nuts::nuts::nuts::nuts::nuts:

It's all in the movement of our earth's crust:cheers:

there is also a possibility that Mindanao will attach to the Borneo while smaller islands in the Visayas will form a one island...

Ganito yan Henz.....Batanes and most of Luzon is on a large chunk of the Eurasian Plate are squeezed westwards more towards the Asia mainland (Vietnam/South China) by the diving Philippine Plate while the large southern chunk of the Asian Plate (southern Mindoro down to the tip of South Cotabato) is equally squeezed on both sides by the Philippine and Eurasian Plate moreover moving to the east.

The opposing movement of these chunks of Eurasian and Philippine plate leaves an area (West to East or the other way around) of fracturing and faulting, slipping past each other...and these areas are Northern Mindoro, NCR, Southern Tagalog and Bicol including Masbate and Leyte.

All in all these complicated movements created more complex faulting and appearance of volcanoes in between (North to South) from Zambales, Bataan, Negros and Northwestern Mindanao. The remaining non-volcanic islands of the Visayas (Panay. Cebu, Bohol and Siquijor) are result of complex faulting, thrust, uplifts and rifting (later to be shaped by erosion and levelling).

In short..(haaaaay) ang Pilipinas ay resulta ng pag uumpugan ng Philippine Plate at Eurasian Plate.....tayo yung nayuyuping part na umusbong pataas mula sa ilalim dagat kung saan sila nagbabangaan.^^

How the quake shifted Japan

Malaya Online, Philippines
BY ALAN BOYLE
March 14, 2011
http://www.malaya.com.ph/mar14/news2.html

This week’s earthquake caused the main island of Japan to shift as much as 13 feet to the east, seismologists say. That may sound like a shocker, but it’s just one of the natural changes that come along with an 8.9-magnitude temblor — like the 1.6-microsecond speed-up of Earth’s daily rotation and the 4-inch shift in Earth’s axis.

The eastward shift was documented by Japan’s Geonet network of GPS monitoring stations, based in Tsukuba, said Ken Hudnut, a geophysicist at the US Geological Survey’s Earthquake Hazards Program in Pasadena, Calif. Similar shifts took place during last year’s 8.8 earthquake off the Chilean coast, as well as the 9.1 earthquake near Sumatra that caused a disastrous tsunami in 2004.

"It’s the same phenomenon in all three cases," Hudnut said. The movement is linked to the release of the strain that builds up when one tectonic plate grinds against another in a subduction zone.

"What’s going on is that the plate going down drags along with it the upper plate as strain is stored in between earthquakes," he explained. "When the earthquake occurs, the upper plate lurches eastward over the subducting plate. The oceanic plate that’s going down is relatively rigid, but the upper plate is like a wedge of material that’s more elastic. So picture that upper wedge as being almost like an accordion that’s being compressed between the times of earthquakes. It’s like a spring. You’re loading up the spring between earthquakes — in other words, you’re compressing the eastern edge of the spring toward the main island of Japan. The earthquake allows that material to spring out toward the east."

Japan’s network of 1,200 GPS monitoring stations, operated by the Geographical Survey Institute, shows a maximum springing-out effect of 13 feet (4 meters), with an average displacement of about 8 feet (2.5 meters) along a stretch measuring more than 300 miles (500 kilometers).

Everything that links GPS readings to maps, ranging from driving directions to property records, will have to be changed as a result of the shift, Hudnut said. "Their national network for property boundary definitions has been warped," he said. "For ships, the nautical charts will need revision due to changed water depths, too (of about 3 feet). Much of the coastline dropped by a few feet, too, we gather."

We’re starting to get pictures from space that document how the coastline has changed due to the earthquake and the tsunami. The NASA photos show the coastline around the city of Sendai, which was one of the hardest-hit areas. The left photo was taken on Feb. 26 by the Moderate Resolution Imaging Spectrometer, or MODIS, aboard NASA’s Terra satellite. The right photo was taken today by the same instrument. You can see that wide stretches of the coast are still flooded, in part because barriers erected at the coastline’s edge are now keeping water in rather than keeping it out.

Other satellite pictures, distributed by Google, provide a closer-in view of the devastation caused by the tsunami. In each of the before-and-after sets below, the left picture was taken before the earthquake and the right picture was taken afterward. Check out Google’s blog posting and this Picasa Web album for additional before-and-after earthquake imagery. (msn.com.google)

No 'Supermoon'-earthquake connection: Scientists

The Strait Times
March 14, 2011
http://www.straitstimes.com/BreakingNews/TechandScience/Story/STIStory_644964.html

The phrase 'Supermoon' is believed to have been coined by an astrologer, Richard Nolle, on his website, and spread to astronomers online

THE mega earthquake that hit Japan on Friday had no connection to the 'Supermoon', scientists said, referring to an event on March 19 when the moon will be at its closest to Earth in 18 years.

Dr Paul Walker, a senior meteorologist for AccuWeather Inc, told ABC News that 'there is no connection between the moon's position' and the 8.9-magnitude earthquake, which is feared to have killed over 1,000 people. 'I don't think you can attribute it to being a full moon... These moon events can cause the tides to run higher than normal, but I've not heard of any correlation between them and extreme weather events,' Dr Walker added.

The phrase 'Supermoon' is believed to have been coined by an astrologer, Richard Nolle, on his website, and spread to astronomers online.

Mr Nolle had written that the last 'Supermoon' this year was just before the earthquake that hit Christchurch, New Zealand, in February. Other disasters occurring near a 'Supermoon' included Hurricane Katrina and the 8.8 Chile earthquake, Mr Nolle said in his post.

However, Nasa astronomer Dave Williams agreed with Dr Walker's view that the moon had no connection to the Japan quake, ABC News reported.

In an e-mail to ABCNews.com, Mr Williams said that at the time of the earthquake in Japan, the moon was actually closer to its furthest point in orbit from Earth than it was to its closest point (on March 19), 'so the gravitational effect of the moon was, in fact, less than average at that time'.

^^ This coming saturday it will be a supermoon (March 19, 2011).
See this link about Richard Nolle astrology prediction re: supermoon phenomenon. He mention in his website that Supermoon has something to do with Mount Pinatubo explosion 3 days before the fullmoon.

not all those lines are trenches. those are just areas of fracturing and labeled sections of the crust that are created by the convergence of plates.

Duterte offers to send rescue team to Japan

DAVAO City Vice Mayor Rodrigo Duterte offered to send a team of Central 911 personnel, at the city's expense, to help in the search and rescue efforts in Japan after a magnitude-8.9 quake and tsunami hit the country Friday.

In a letter dated March 14 addressed to Japan Prime Minister Naoto Kan through Consul Yoshiyuki Isoda, director of Japan Consular Office in Davao, Duterte said the offer is the city's expression of solidarity and gratitude for all the assistance that the Japanese government has extended to Davao through the years.

Post your online prayers for Japan earthquake victims

"We know that any help that can be extended to support your rescue efforts can be significant hence, Davao City offers you a team of its search and rescue personnel from its Central Communications and Emergency Response Center - Central 911 at our expense to help you in your efforts," Duterte said in his letter, which he personally delivered Monday to Japan Consular Office in Plaza de Luisa Complex on Magsaysay Avenue, Davao City.

The vice mayor said Davao City has a huge number of Japanese migrants especially in Mintal, dubbed as "Little Tokyo," because it used to be settlement area of Japanese nationals during the pre and post World War II period.

Citing the innumerable Japan-funded projects in the city, Duterte said it is about time the city show its gratitude to the Japanese government and its people who are now faced with unimaginable deprivation.

More than 10,000 people are estimated to have died in Friday's double-headed tragedy. Reports said that in many areas there is no running water, no power and four to five-hour waits for gasoline, and people suppressing hunger with instant noodles or rice balls while dealing with the loss of loved ones and properties.

"No words can express the grief, agony and worry that we feel for your country and people as we watch scene after scene of devastation, death and destruction unfolding before our eyes in TV screens all over the city," Duterte added.

"But we comfort ourselves with the thoughts that Japan, finding strength in its resiliency and disciplined citizenry, will rise from this tragedy, stronger and more progressive than ever," he added.

In expressing confidence on Japan to rise up again, Duterte said "the tragedy and the speedy recovery of Kobe, Japan not too long ago is a testament to your country's determination to triumph over disaster however destructive it may be."

Davao City can only offer prayers, Duterte added, with the wish that as Japan confronts the problems besetting the country and start with recovery, God will always be with there to lead, guide and protect.

CEBU City officials responded to the tsunami disaster by offering to send a medical rescue mission to Japan.

Rep. Tomas Osmeña of south district announced the plan in an emergency meeting in City Hall with Acting Mayor Joy Augustus Young.

Young said the city government would spend for 20 to 30 volunteers who would be sent to Japan once a written request is made by the government.

“I've never heard of Japan asking for help before except for this one. This must be big a one that they were compelled to ask for help,” said Young.

Mayor Michael Rama left for abroad yesterday, reportedly to Hong Kong for some private time. He was not available for comment.

“The only way we could help Japan that I can think of, ” said Congressman Osmeña, “is to send a medical mission there. We have not yet been asked to send one yet, but in case the do, we have to be ready.”

He said the city government would need a written request from Japan asking for volunteers. Osmeña said nurses and medical experts who are experienced in trauma and disaster response may apply.

I think each city or province should send a few representatives from their best rescue and emergency team to form a conglomerate Philippine Rescue Team for Japan

Anyway, just to be fair enough and seemingly timely, PHIVOLCS has released some tsunami hazard maps from their study sometime after the big 2004 Indian Ocean tsunami and quake. Here are some of the Western Visayas provinces that WILL be affected if a magnitude 7 or 8 earthquake ruptured in Negros Trench. This involves the entire region within Panay Gulf area.

It simply shows that wishing for disasters and ill-wishes are not to be taken lightly, especially when other people are at risk as well. We're talking about thousands dead or missing, millions of pesos lost, cities over-run and basic services overwhelmed. Japan just gave us a glimpse on how Mother Nature isn't kidding at all.

http://www.nasa.gov/mission_pages/hurricanes/archives/2011/h2011_Arani_prt.htm

^^so it will be second if it will make landfall to be a recorded cyclone since 1966
like Hurricane Catarina. 1st recorded )since 1966) South Atlantic Storm which struck the state of Catarina in the Southeastern portion of Brazil some 520 miles to the southwest of Rio De Janeiro On March 25, 2004.

meron rin ata last year, pero di ko lang sigurado kung may pangalan...
di tulad nung Catarina, eto ay papalayo ng lupa

:cheers:

i really hope we could have a warning system similar to Japan...

wala pa yung mismong earthquake pero na-alertuhan na nila ung public... kahit isang minuto lang, marami ang maliligtas nito, lalo na sa pilipinas...

Ito po sir, with English subtitles... :)

Anyway, just to be fair enough and seemingly timely, PHIVOLCS has released some tsunami hazard maps from their study sometime after the big 2004 Indian Ocean tsunami and quake. Here are some of the Western Visayas provinces that WILL be affected if a magnitude 7 or 8 earthquake ruptured in Negros Trench. This involves the entire region within Panay Gulf area.

It simply shows that wishing for disasters and ill-wishes are not to be taken lightly, especially when other people are at risk as well. We're talking about thousands dead or missing, millions of pesos lost, cities over-run and basic services overwhelmed. Japan just gave us a glimpse on how Mother Nature isn't kidding at all.

The biggest question is, does our local governments ready for such?

As expected, inlets and bays despite the small area amplify tsunami to heights more than forecasted (like in Minamisanriku, Kamiashi). Alluviual plains of Negros Occidental are very susceptible to far inland run-up just like what you see in most of Sendai and Fukushima. And owing to the fact that the coastline Bago down to Cauayan "catches" the direct impact if the waves originated from Sulu Sea on a NNE and NE direction

The first step should be education and awareness....have it more visual with videos and pictures. Just what like Maurice and Katia Krafft did to Centtral Luzon to convince them to evacuate from Mt. Pinatubo

How were they able to predict the earthquake? they said it cant be predicted???

there's no way earthquake can be predicted. Monitored, yes.:)

^^ There is this one theory about anomalies in ground movement. If there is a part in the fault line that doesn't move, it is prone to "snapping" or earthquakes--the strain energy it keeps may provide a bit of forecast.

I guess the same science as this one that is being implemented in DF (Mexico City)

Marikina West Valley fault line
capable of 7.2 magnitude earthquake –- Phivolcs chief

MANILA, Philippines (PNA) – The Marikina West Valley fault line, one of the active faults in the country, can cause a 7.2 magnitude earthquake at its full movement, Philippine Institute of Volcanology and Seismology (Phivolcs) Director Renato Solidum said on Tuesday.

Solidum clarified, however, that such magnitude of the fault’s tremor occurs only when it reaches its full capacity.

“It may also cause a tremor at the magnitude of just four or five,” he said at The Forum of the Catholic Media Network (CMN) and the Catholic Bishops Conference of the Philippines (CBCP) News at the Ilustrado Restaurant in Intramuros, Manila Tuesday morning.

At the same time, Solidum allayed fears that a tsunami of the same magnitude as the one that occurred in Japan would happen in the country because the earthquake’s magnitude here is not as much as the Japanese earthquake that was already certified by international seismologists as having reached magnitude 9.

He said that "our top concern now is on how much we are prepared. Everyone must do what he has to do to be ready for any earthquake phenomenon, like conducting earthquake drill in schools, malls, churches and other establishments.”

He explained that lower buildings are likely to be swayed stronger than high-rise buildings because the shaking is quick and short.

The seismology expert illustrated this by shaking a small piece of plastic with three vertical figures -- short, medium and tall. When swayed fast, the short one shook stronger but when the sway was slow and gradual the taller figure shook.

Solidum assured everybody that Phivolcs is closely monitoring the Marikina West Valley fault, which protrudes through Muntinlupa and Makati.

Likewise, the agency pays similar attention to the other faults that can trigger strong magnitude earthquake like the Philippine Fault Zone that transects the whole archipelago along a general strike of 30 degrees North to 40 degrees West from northwestern Luzon to southern Mindanao, the Phivolcs head said.

yes, almost the same thing... kokonti pa lang may ganyan sabi sa wiki, Mexico, Japan, at Taiwan pa lang...

here's a simple explanation from JMA...:)

^^ If Mexico can, why can't we?

How were they able to predict the earthquake? they said it cant be predicted???

Predict...not yet. But pinpointing where, that is what they are doing now. its by putting telemetric instruments to measure ground movement that indicates stress and probable site of fracture...this is correlated with the specific fault's history. But as to when or how strong..naaaah...not yet. Speculation pa lang.

Although in 1975, in the city of Hiacheng ?), residents were warned of a probable oncoming earthquake after a series of unusual events occurred. Water in level of wells were changing, animals seemed disturbed with chickens refusing to roost and horses running all over. It was accompanied with groaning and rumbling sounds heard beneath at night. After weeks of preparing, a mmagnitude 7 earthquake struck the city with no casualties....luck or high scientific index of suspicion? ^^

yeah, ung sa Haicheng na predict nga nila, tsaka may foreschock ata nabasa ko sa Wiki... may isa pang kaso din nyan, sa China din pero di ata pinakinggan nung mga residents...

ung sa Japan diba may foreschock din na nangyari kaso di nila siguro in-expect na magiging 9.0 ung "afterschock"...:(

Ahh...early warning system sa earthquake?...hmmmm...not that very possible...but on a tsunami yes....dapat automatic yan like in Japan.

Once the seismographs register a magnitude 6.0 and above, the warning system automatically goes on. And this is relayed to NHK, Asahi and local government agencies. the sirens would blare at once on the areas with warnings. On TV, an ongoing show will be interrupted and a map of Japan with color coded warning areas will keep on blinking all over again. These caught the Japanese on their heels.

Pero it is very automatic and natural to Japanese living along coastlines na tumatakbo na papuntang elevated areas and buildings (5th floor) pag nakaramdam ng malakas na lindol. The seaports automatically uses their tsunami barriers and gates and close the port area. This system was developed after the devastating earthquake and tsunami of the Sanriku Region (now Miyagi and parts of Iwate and Fukushima Prefecture) in 1896 and 1933. But the Sendai quake and tsunami of 2011 is a hundred times greater and had tsunamis larger.

Foreshocks?...this would only be realized AFTER the earthquake (main shock). :ohno:

The August 17, 1976 earthquake (and tsunami) in Moro Gulf had 2 foreshocks (mag. 6) months and a year before.

The Sendai Quake 2011 had 3 quakes (mag. 6-7) occuring close to each other 2 days before the 8.9(9.0)main shock.

but who would think that these quakes are just foreshocks?...that's the dilemma there...:ohno:

one thing more....the quake epicenter might be too near the shore that tsunamis will come surging at the shore in less than 5 minutes (e.g. Calapan and Baco, Oriental Mindoro Nov. 15, 1994). So the warnings will come in quite late, just what happened in Sendai (10 minutes lang):ohno:

Is our Capital ready for a Major Earthquake?..

good point... at tsaka, di mo rin alam talaga kung kelan ang susunod na afterschocks, kung meron man...

as for the earthquake warning system, meron akong pinost na video galing sa Japan (Fraulein w/ english subs)...:) it's not really a prediction, alert lang sa public as soon as nag-register na ung wave sa mga computers nila.. one minute lang ata ang headway pero malaki na rin ang maitutulong nyan

^^ IMO, a minute preparation provides a big help.

WE NEED THAT ASAP!!!

so ironic when a 6.0(and above) earthquake hits the Japanese shoreline and you're on the 5th floor of a builiding the tendency is you go down then climb-up again because of eminent tsunami, i guess it's "routine" from these areas.

hehehehe....sanay na sila...check out NHK TV video of the evacuation of Kamaishi City 5 minutes after the tremblor. (also in Minamisanriku and Tarou)

HISTORIC EARTHQUAKES OF THE SANRIKU REGION

note: all epicenters have occurred in the same area of the trench with tsunamis

July 13, 869 - "The Jogan Sanriku Earthquake" - Sendai (Iwate, Miyagi area) - tsunami reached as far as Washington and Oregon, USA and British Columbia, Canada

June 15, 1896 - M 8.2 "Meiji Sanriku Earthquake" - Iwate, Sanriku, Kamaishi, Tarou (Iwate, Miyagi area) - tsunami pacific-wide

March 2, 1933 - M 8.4 "The Great Sanriku Earthquake and Tsunami" - Iwate, Sanriku, Kamaishi, Ofunato, Tarou (Iwate, Miyage area) - tsunami pacific-wide

March 11, 2011 - M 9.0 "The Great Tohuku Earthquake" - Sendai, Minamisanriku, Iwate, Fukushima (Iwate, Miyagi, Fukushima, Ibaraki Prefectures) - tsunami Pacific-wide

After 1933, the Sanriku Region especially the city of Tarou was protected by cris-crossing tsunami walls at 10 meters and became the "model city" for tsunami preparedness, but the latest tsunamis topped at 14 meters destroyed 90% of the area

:ohno::ohno::ohno::ohno::ohno::ohno:

This only shows that Human has its limits but natural disasters has none. We might be able to at least lessen our ordeals but we have to live with it.

I admire Japan's infrastructure especially on its buildings. Only a few buildings failed after the strong earthquake. They have their own standard of designing buildings due to earthquake.

This only shows that Human has its limits but natural disasters has none. We might be able to at least lessen our ordeals but we have to live with it.

Nature creates and breaks its own rules...:ohno:

by the way, I just note that the Japanese like to give titles to their historic earthquakes. Other than what I have posted a short while:

1923 - The Great Kanto Earthquake - a devastating earthquake followed by a firestorm reduced Tokyo and Yokohama cities to ash - 134,000 dead

1995 - The Great Hanshin Earthquake - destroyed the port city of Kobe with 6,500 dead

^^ Because we live at her mercy. Nature is also the multiverse we are living. :D

PHIVOLCS: Magnitude 6.1 Earthquake Hits Northern Luzon


A magnitude-6.1 quake rocked parts of northern Luzon Sunday afternoon, with residents from as far as Manila feeling its effects.

Phivolcs director Renato Solidum Jr. said the quake was recorded at 4:26 p.m., with the epicenter at 117 km northeast of Laoag City.

"Ang pinakamalakas so far sa Intensity V. May report sa Manila nakaramdam (So far we received reports the quake was felt at Intensity V. There were reports people in Metro Manila also felt the quake)," he said in an interview on dzRH radio.

He said the quake was not related to the magnitude-9 quake that hit Japan last March 11.

Phivolcs: Magnitude-5.8 quake hits Luzon

GMANews.tv

http://www.gmanews.tv/story/215831/nation/phivolcs-magnitude-58-quake-hits-luzon

A magnitude-5.8 quake rocked parts of Luzon, including parts of Metro Manila, Monday night, a day after a magnitude-6.1 quake hit Northern Luzon.

Philippine Institute of Volcanology and Seismology head Renato Solidum Jr. said the quake was recorded at 6:36 p.m., and was tectonic.

"Ito ang initial estimate, may magnitude 5.8, ang lalim ng lindol 34 km. Ang epicenter malapit sa Lubang Island. Sa tingin namin gumalaw ang fault," Solidum said in an interview on the newscast "24 Oras."

(Our estimate is that the quake was magnitude 5.8, about 34 km underground. We estimate the epicenter to be at Lubang Island.)

Citing initial reports reaching him, he said the quake was felt in Manila, Quezon City and Makati City. He said the quake was not connected with the magnitude-6.1 quake that hit Northern Luzon Sunday.

Solidum said Sunday's quake stemmed from the Manila Trench while Monday's quake was traced to the Lubang Fault.

The United States Geological Survey measured the quake at magnitude 5.4, and estimated the epicenter at 57 km west-northwest of Batangas; 88 km south-southwest of Manila; or 90 km northwest of Calapan, Mindoro.

Separate reports on dzBB said the quake was felt in Manila, Quezon City, Taguig, Batangas, and Mindoro.

Know what, sometimes this overpreparedness lulls people to a sense of false security. This is also what contributed to a lot of casualties. The Japanese coasts are dotted with so many elevated hillsides which are actually quite readily accessible. Even if the time was short of 15 or 20 minutes before the first waves came, that would have been ample time to run up the nearest elevated place. However, people felt too safe behind the high seawalls and thought these were insurmountable by any tsunami. You can see from some videos that some people were even not running away but staying put and looking at the wave in the distance until the waves closed in and they were too late to escape.

The thing is I often work in the field just in front of the Philippine Sea arm of the Pacific in Kochi, Shikoku and I was actually caught in the middle of fieldwork when the projected 1.5 to 2-m tsunami of the Chile quake reached the area in February last year. In all honesty, I wasn't scared at all because the seawalls were much, much higher than 2 meters and luckily it didn't hit that hard. I was even a bit excited to witness it. I like the feeling of dread and awe mixed together whenever I witness these displays of nature's power.

I think that If I were there in the Sanriku area on that very same day, I would have perished along with several others. I would have thought that the 10-m walls were enough to protect me, and I would have been curious enough to watch the wave.

Wala sa Pilipinas but Myanmar has been hit by magnitude 6.8-7.0 earthquake just a few minutes ago.



...and wherever the Azkals are, andun ang lindol?

^^ The Gods are applauding for the Azkal team! but Azkals don't bother to step on our doorstep, i'm contented cheering for you afar!

^^The Azkals panicked last night. Their hotel is in the 9th floor of a hotel watching a video of the Bangladeshi team. When the tremor began, most of them ran downstairs passing through the fire exit doors. lol

^^The Azkals are chickens! :lol: Kidding aside, anyone would've panicked (degree would vary though) in that situation.

May mga years yata na kung saan naka cluster ang major earthquakes.

1976 - Tangshan, China; Moro Gulf, Philippines; Guatemala City, Guatemala

1990 - Manjil, Iran; Antique, Philippines; Cabanatuan, Philippines

2010 - Port Au Prince, Haiti; Maule, Chile

The buildings in Japan were also designed to resist shear force due to earthquakes. they have their own standard of design with regards to the design of building frames that could resist strong earthquakes. Some of the houses though were made from simple materials for economy. Lucky are those people who live in sturdy buildings that were not washed away by the tsunami

So a rough estimate of its roof is about 6-7 meters ++ above the ground. di naman malulubog ang SM Bacolod if mga 3 meters lang ang highest wave, but if the vertical run-up is large and strong as it runs-up the slope of Rizal St. to wards the Plaza the water may rise up more higher as it pools back at the reclamation area (BREDCO) which is lower than the city plaza and CBD.

hmmmm...as to my strong index of suspicion, it has a big chance of occurring. La Nina is ending and a neutral phase will occur...hmmm...thats very fertile for a tropical cyclone...

Remember there is no definite typhoon season of the Philippines. We have typhoons all-year-round

About earthquake news on media, should there be a standard what tremor to report or not? I can see that even magnitude 3 earthquakes made it to news.

^^ very interesting... ilang models na ang nag-hint ng development this week.. pero mahina generally, siguro mga tropical depression lang, tsaka since mukhang mahina naman ata ang STR ngayong week, eh baka mag-recurve.... sana...

pero bilib ako sa forecasts nya ah!

^^ECMWF model shows the current LPA southeast of Mindanao will form in the next 3 days and eventually recurve to the Northeast direction...:yes:

Tropical depression 'Amang' enters PHL
By ELLALYN B. DE VERA
April 4, 2011, 12:43pm

MANILA, Philippines – A low pressure area (LPA) east of Visayas has developed into a tropical depression named “Amang,” according to the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA).

“Amang” is the first cyclone to enter the Philippine area of responsibility this year

And AMANG is "snubbing" us because he's moving East away from the Philippines

And AMANG is "snubbing" us because he's moving East away from the Philippines

Yeah right. At least we are still enjoying the summer heat... :)

that invest was such a tease.. a lot of potential had the conditions been favorable... mukhang mag-aantay uli tayo para sa next tropical storm

^^ Heat? I haven't felt much heat yet as compared to previous years.

I also observe that. But still, no more expected rains this summer... for at least :)

malamig ang umaga dito sa Cebu ngayon :)

Remember La Nina is still here 'til late April or early May

so we will expect more rains? summer is not that hot compared last year though.:)

Remember La Nina is still here 'til late April or early May
Does La Niña enhance north-eastern winds?

so we will expect more rains? summer is not that hot compared last year though.:)

Yep, not that much but rains will still be observed throughout this "late summer"
A high pressure ridge is quite building up in the NE of the Philippine Sea to the Northern Pacific, this might herald the weakening NE Monsoon and give way to the easterlies

Does La Niña enhance north-eastern winds?

That depends if the La Nina still dominates over strong lows over Australia or Indian Ocean....

But as of the moment its the Easterlies that are dominating our weather and surges of the NE Monsoon are just cutting-in....these easterlies are bringing tropical disturbances straight to our country but the dry conditions of our sea are not favorable for typhoon formation...the convergence of the NE Monsoon and warm Easterlies are creating these rains

^^ Would that easterlies be dominant in Vis-Minda area instead of Luzon? For the past few weeks, we have been experiencing the same cool weather as it is supposed to be experienced during January-February. Although there are times that it cuts itself and return to the hot-humid days, but the cold, dry, windy nights and days still dominate.

Reminds me of singing "Cold Summer Nights." :D

At first yes....the Eastern Seaboard including Bicol...but generally the Easterlies affect the entire eastern Philippines...the strong NE monsoon surge is sputtering-off but because of La Nina, its lingering a bit longer...naughty girl :bash:

here in BCD, we should be expecting a temp range of 27-33 degrees celsius for April...but we are still having an average low of 24 and high of 31-32 degrees...

Coz if the general prevailing concept of La Niña is wet weather, Manila or northern and central Luzon hasn't been receiving that much rain. It has been dry for most of the time and yes, Visayas has been very very wet.

^^same here in Cebu... lows of 24C and 29 to 31 by noon time. Then now is kinda cool same in the morning knowing that it's already April.
Usually, aabot na sa about 33 or 34 siguro pag April...

Summer days and rainy nights here in Davao. well unusual 20 years ago but not 40 years ago.

Aw sorry, I mixed it all up.....hehehehehee...I stand corrected...let me rephrase averything

La Nina isn't necessarily wet (although rainfall is usually increased in a La Nina Period for the Philippines)...its actually a "cold episode" of the sea...where warm seas as expected near Phil and Indonesia are warmer than its usual mean temp by this given time...more evaporation, but the very strong Easterlies blow off condensing thunderstorms and developing typhoons nearer the Philippines thus despite numerous rainy conditions, these typhoons don't form or if they do, not so intense (with the exception if favorable conditions like the Madden-Jillian Oscillation, weak shear winds that may occur) Maybe what happens here presently is the (unusually) strong NE monsoon in convergence with the warm Easterlies in a weakening La Nina creates these outbursts of rain between sunny to overcast interludes on parts of the country near the equator giving us cooler breezes than the expected warm ones. On a neutral period the Easterlies dominate and the NE monsoon doesn't reach PAR, thus a drier climate[/QUOTE]

Aquino unveils 3-D mapping project

By Norman Bordadora
Philippine Daily Inquirer
First Posted 13:27:00 04/08/2011

URDANETA, Pangasinan, Philippines—President Benigno Aquino III announced Friday the allocation of P1 billion for the creation of a three-dimensional map of the entire country that is designed to improve flood forecasting and related early warning systems.

Mr. Aquino made the announcement during the inauguration of the new P243-million Agno River Basin Flood Forecasting and Warning System in the nearby town of Rosales.

“One of our proposals is the development of a comprehensive 3-D mapping of the whole Philippines. We will release P1 billion for this,” the President said in a speech. “With this mapping, our perspective of every corner of the country will widen, resulting in an improved capability to know which areas are vulnerable to floods.”

The President said this will also give the government more time to help Filipinos at risk from flooding.

“There might be some who'd protest the amount of money that will be spent on this project. They might ask how come such a huge amount of funds would be released. Let me just stress (that) lives would be saved here,” he said.

The Agno River Basin Flood Forecasting and Warning System is an early warning facility meant to provide timely, reliable and understandable flood warnings and bulletins in the provinces of Tarlac and Pangasinan.

The project cost a total of P243 million, including a P154-million grant from the Japanese government through the Japan International Cooperation Agency.

“The flood forecasting and warning system is equipped with automatic monitoring stations that observe every hour, in real time, the intensity of rainfall and the level of the Agno River and its tributaries, including Sinocalan River,” said Nathaniel Servando, acting administrator of the Philippine Atmospheric, Geophysical and Astronomical Services Administration.

The observed rainfall and river heights would then be transmitted by radio to the monitoring centers concerned.

“In the event of an impending weather disturbance such as a tropical cyclone, the observed data together with the forecast rainfall from DOST-Pagasa are analyzed to come up with forecast flow or water level in the Agno River which serve as basis for the issuance of flood warnings,” Servando said.

President Aquino renewed his commitment to the improvement of Pagasa's weather forecasting system and thanked Japan for its assistance to the Philippines.

“With the help of the Department of Science and Technology, we were able to hasten the implementation of our initiatives and objectives (related to the safety and welfare of our citizens),” the President said.

“The DoST is ensuring that the improvements in the facilities of Pagasa would be continuous,” he added.

Mr. Aquino pointed out that the country now has more and better automatic weather stations, rain gauges, Doppler radars, flood monitoring and forecasting systems.

“We have phased out antiquated equipment. The DoST is also developing sensors against landslides, tsunami and red tide,” Mr. Aquino said.

“The good thing here is that these will be made and designed here in our country. Through this process, we will be able to save and allocate more funds to other projects,” he added.

Among those present at the inauguration was Japanese Ambassador Makoto Katsura.

“Let me take this opportunity to thank the Japanese Government for their enduring partnership with our country. The completion of this (flood forecasting and warning system) is timely as we celebrate 55 years of cooperation with your country and the 43rd Anniversary of Japan’s technical assistance for Pagasa,” the President said.

“More than a neighbor, you are a brother to the Filipinos. This is why we did not hesitate to lend a hand to your people these past months when you have faced many challenges brought about by the earthquake and the tsunami. We share our sympathies with your people,” he added.

“It is doubly gratifying for us that you have found the time and effort to support this project. These gestures show that humanity and compassion extend farther than geographic and cultural borders. I thank you in behalf of every Filipino,” Mr. Aquino said.

Katsura thanked the Philippine government for its share in helping Japan in the aftermath of the earthquake and tsunami.

“Even under the difficult circumstances where Japan is placed right now, our commitment to extend assistance to the Philippines remains unchanged and we intend to continue to help improve the living environment of the Filipino as much as possible,” Katsura said.

Hmmm...and where are those said doppler radars (since 2006)

recent 5.2 in capital? this could be a sign..im no fairy god..relative to japan they had series of 4-5 magnitude quakes for weeks b4 the big one hit. kis-kis ng kis2x ung mga faults..
maybe OT: sabi rin ng mga scientists sa japan the earthquake in sendai was a 1000 yr event..coz they studied it..sa mga soil deposits..that also brought a tsunami in that area..etc..just research :)

^^ The 9.0 Sumatra earthquake in 2005(?) still had strong aftershocks in months, even recorded an 8.0 a year after. for the record the earthquake recorded a 20 meter(8-storey bldg.) waves in some parts of Sumatra.

Your quite right with that...to review, here are the historic earthquakes of the Tohoku (Sanriku) Region. All of them are tsunamigenic

July 9, 869 - "Jogan Sanriku Earthquake" - off the coast of Iwate Prefecture - Mag. 8.6 - est. 1,000 deaths - tsunami floods Sendai Plain (max height 26.7 m., horizontal run-up 4 kms inland) - tsunami reached and flooded coastal areas of British Columbia, Oregon and Washington

June 15, 1896 - "Meiji-Sanriku Earthquake" - off the coast of Iwate Prefecture - Mag. 7.2 - 22,061 deaths - tsunami floods Miyagi (Sendai), Iwate (Sanriku, Tarou) with max height of 38.2 meters - tsunami reached coasts of Hawaii with considerable damage until California (9-9.5 meters)

March 2, 1933 - "The 1933 Sanriku Earthquake" - 290 kms East off the coast of Kamaishi, Iwate Prefecture - Mag. 8.4 - 3,000 deaths - tsunami destroys Ofunato, Iwate Pref. ( max 28.7 meters), Kamaishi -Sanriku and hardest hit Tarou, Iwate Pref. - tsunami reached Napoopoo Bay, Hawaii (max 2.9 meters)

:ohno::ohno::ohno::ohno::ohno::ohno:

March 11, 2011 is just the biggest event of them all when it was overdue (as predicted 2001) at 1,100 years...:ohno:

Indonesia is just an "overlooked" area of tsunami since most of the focus is on the Pacific Rim, and Indonesian tsunami were always recorded to be "local" and not like the 2004 Indian Ocean-wide

i have researched remarkable Indonesian Tsunami's...marami din but not much have been written but recent studies noted that the western coastline of Sumatra have been haunts of historical tsunamis that have moved coral blocks and coral debris inland as evidenced by layers found in 2004 and 2005 explorations

Phivolcs raises Taal alert to ‘2,’ warns of eruption
04/09/2011 | 09:17 AM (http://www.gmanews.tv/story/217349/regions/phivolcs-raises-taal-alert-to-2-warns-of-eruption)

Citing at least four disturbing recent trends indicating an eruption, state volcanologists on Saturday raised the alert level at Taal Volcano in Batangas to “2."

The Philippine Institute of Volcanology and Seismology (Phivolcs) said an eruption is possible as there are signs of magma rising to the surface.

“In view of the above observations at Taal Volcano and the interpretation that magma has been intruding towards the surface, as manifested by (carbon dioxide) being released in Main Crater Lake and the increase in seismic activity, Taal Volcano’s status is now raised to Alert Level 2. With this alert status, the present activities could eventually lead to an eruption," it said in its website.

With the raising of the alert level, Phivolcs advised the public that the Main Crater, Daang Kastila Trail and Mt. Tabaro are strictly “off limits."

Mt. Tabaro was the site of an eruption in 1965, it noted.

Phivolcs pointed out sudden hazardous steam-driven explosions may occur and high concentrations of toxic gases may accumulate in those areas.

In raising the alert level, Phivolcs noted “significant changes" as indicated by the following observations:

1. Seismic activity at Taal Volcano continued to worsen, as the number of volcanic earthquakes detected gradually rose and the depths of the plotted quakes are becoming shallow (1 to 4 km).

There is also an increase in the number of perceptible quakes. During the past 24 hours, two quakes were felt at the Volcano Island with Intensities ranging from II to III and one of them was accompanied by rumbling sounds.

At least 21 volcanic quakes were detected by the seismic network for the past 24 hours.

2. Gas measurements conducted at Taal Main Crater Lake yielded carbon dioxide emission flux of 1,875 tons per day (t/d) in February 2011 and 4,670 t/d during the last week of March 2011. The remarkable increase in carbon dioxide concentration indicates its release from the magma at depth.

3. Ground deformation survey (precise leveling) conducted around the Volcano Island this week showed that volcano edifice is still inflated as compared with February 2011 survey.

4. Steaming activities at the northern and northeast sides of the Main Crater occasionally intensified. Sometimes, intensification of steaming activity is accompanied by audible hissing sounds.

Phivolcs also reiterated its warning that breathing air with high concentration of carbon dioxide can be lethal to humans and animals, and can damage vegetation.

It likewise reiterated the entire Volcano Island is a Permanent Danger Zone (PDZ), and permanent settlement in the island is strictly not recommended.

Bulusan, Mayon still at alert level 1

Phivolcs said Bulusan Volcano in Sorsogon and Mayon Volcano in Albay remain under Alert Level 1.

It said Bulusan had at least two volcanic earthquakes during the past 24 hours.

Entry to Bulusan’s 4-km radius PDZ is strictly prohibited, since the area is at risk to sudden steam and ash explosions.

“Due to the prevailing wind direction, residents in the northwest and southwest sectors of the volcano are reminded to take precautions against ash-falls," it said.

“Furthermore, people living near valleys and river/stream channels should be vigilant against sediment-laden stream flows and lahar in the event of heavy and prolonged rainfall," it added.

As for Mayon, Phivolcs detected two rockfall-related events during the past 24 hours while steam emission varied from wispy to moderate and drifted towards the southwest direction.

Fair crater glow (Intensity II, can be seen by the naked eye) was observed Friday night.

“Although this means that no eruption is imminent, it is recommended that the public should not enter the 6-km PDZ due to the continuing threat from sudden small explosions and rockfalls from the upper and middle slopes of the volcano. Active stream/river channels and those perennially identified as lahar prone areas in the southern sector should also be avoided especially during bad weather conditions or when there is heavy and prolonged rainfall," it said. — LBG, GMA News

^i hope people are safe..and they dont underestimate mother nature :).

Taal for me is the Philippine's most dangerous volcano...imagine bawat quiet repose nito ay sinusundan ng violent eruptions. Pinatubo (1991) and Mayon (1814) had their share of violence with a Plinian Eruption (the most violent of all eruption classes) but nothing beats the lowly Taal Volcano who had "only" Phreatomagmatic eruptions which made international headlines and landed in National Geographic in 1912 (for the 1911 eruption) and Life Magazine in 1965.

Most violent eruptions (1754, 1911, 1965)

January 27-Feb.8, 1911 (main eruption 2:20AM January 30) -Main Crater - 1,335 killed

September 29-30, 1965 - Southwest flank of the Main Crater (now called Mt.Tabaro/Tabaro Crater) - 300 dead and missing - the term "base surge" in volcanology was first observed and originated here

http://i269.photobucket.com/albums/jj75/abudominic/Taal_trees1965basesurge.jpg

The presence of Taal Lake and the Lake on its Main Crater is the obvious recipe for its violence and unpredictability (sudden violent explosions).

1754 - 6-month long Phreatomagmatic Eruption sunk the towns of Tanauan, Lipa, Bauan and Taal (used to be lakeshore towns prior 1754)

last eruption was 1977...thats quite long na...but remember Taal's longest quiet phase was 1911-1965 (54 years)...and 1977-present is now the 2nd longest (34 years)....kakatakot yata. Taal had a strong seismic crisis in 1991 and 1993...which reached Alert Level 3. :ohno:

heto guys:

Taal Volcano Bulletin 09 April 20117:00 A.M.

his is a notice for the raising of the alert status of Taal Volcano (14°00.1’N, 120°59.6’E) from Alert Level 1 to Alert Level 2.

Following the issuance of the volcano advisory on 31 March 2011, the monitored parameters have shown significant changes as indicated by the following observations:

1. Seismic activity at Taal Volcano continued to worsen. The number of volcanic earthquakes detected gradually rose and the depths of the plotted quakes are becoming shallow (1.0-4.0 km). There is also an increase in the number of perceptible quakes. During the past 24 hours, two (2) quakes were felt at the Volcano Island with Intensities ranging from 2-3 and one of them was accompanied by rumbling sounds. Twenty-one (21) volcanic quakes were detected by the seismic network for the past 24 hours.
2. Gas measurements conducted at Taal Main Crater Lake yielded CO2 emission flux of 1,875 tonnes per day (t/d) in February 2011 and 4,670 t/d during the last week of March 2011. The remarkable increase in C02concentration indicates its release from the magma at depth.
3. Result of the ground deformation survey (precise leveling) conducted around the Volcano Island this week showed that volcano edifice is still inflated as compared with February 2011 survey.
4. Steaming activities at the northern and northeast sides of the Main Crater occasionally intensified. Sometimes, intensification of steaming activity is accompanied by audible hissing sounds.

In view of the above observations at Taal Volcano and the interpretation that magma has been intruding towards the surface, as manifested by CO2 being released in Main Crater Lake and increase in seismic activity, Taal Volcano’s status is now raised to Alert Level 2. With this alert status, the present activities could eventually lead to an eruption. Hence, PHIVOLCS advises the public that the Main Crater, Daang Kastila Trail and Mt. Tabaro (1965 Eruption Site) are strictly off-limits because sudden hazardous steam-driven explosions may occur and high concentrations of toxic gases may accumulate. Breathing air with high concentration of gases can be lethal to human, animals and even cause damage to vegetation. In addition, it is reminded that entire Volcano Island is a Permanent Danger Zone (PDZ), and permanent settlement in the island is strictly not recommended. DOST-PHIVOLCS is closely monitoring Taal Volcano’s activity and any new significant development will be immediately relayed to all concerned

vulnerable ba ang Manila sa epekto ng Taal, sakaling pumutok (wag naman sana)??

That depends on the violence of its eruption...but ashes reached Manila in 1911.

During the 1911 eruption, the thunderous booming sound of the explosion at 2:20AM of January 30 was heard over a diameter of 360 kms and the electrical display of the monstrous ashcloud was visible 400 kms away.

May I share you excerpts of written observations, visual accounts of the 1911 eruption as compiled in Thomas Hargrove's book MYSTERIES OF TAAL as it was written by Fr. Miguel Saderra Maso,SJ; assistant director of Manila Observatory (now PAGASA), Fr. Algue, Mr. Charles Martin (US Gov't Photographer), F.H. Noble (Album of Views of the 1911 Eruption); all included in an article published by Mr.Dean Worcester in the April 1912 edition of National Geographic ("Taal Volcano and its Recent Destructive Eruption")

"Taal remained ominously quiet until the night of 27 January 1911 when seismographs in Manila Observatory began to register disturbances...shocks soon increased in fequency and intensity...by midnight 26 distinct shocks have been recorded; next day 217..." - Hargrove, "The Killer Eruption of 1911,p.161, MYSTERIES OF TAAL,

"the frequent and increasingly strong earthquakes caused much alarm in Manila...but the observatory staff was soon able to locate the epicenter: Taal Volcano" - Worcester

"...Their intensity in Manila ranged from IV on the earthquake scale of De Rossi Forel (strong enough to shake moveable objects and chairs, and windows) to VII (strong enough to overturn moveable objects, shake off plastering,etc...)" - Fr. Sadera Maso,SJ


"At 2:20 AM came two terrific explosions that tore most of the floor of the main crater of Taal Volcano and hurled it skyward....A huge black cloud rose above the volcano with: a most extraordinary electrical display which was visible for 250 miles (400 km). The exploaion was heard over an area more than 600 miles in diameter...In Kalinga-(in the mountains of Northern Luzon at least 200 kms to the north), the wild men thought that dynamite stored at Lubuagan by the government for the use in road construction has exploded....IN MANILA...the shock of the explosion was so great that people leaped from their beds in terror, thinking that some great catastrophe in the city. Their attention was instantly attracted by the glare of electrical display...the thousands who witnessed the extraordinary sight agree that it beggared description, and few...have even attempted to describe it. The streams of electrical fluid seemed...of extraordinary breadth...the electrical display...added greatly to the terrors of the phenomenon. (From Manila) it had the appearance of an unusually violent thunderstorm - except there were no clouds, the brightest clouds being visible through rifts in the huge black masses of smoke, ashes and mud...the electrical discharges reached a height of 15 kms and were 19 kms in diameter...globes of fire which rose and fell in graceful curves" - Fr. Maso, Fr. Algue, Dean Worcester

:cheers:

if you live along Cavite or Batangas, try asking your middle-aged to old folks on the 1965 Taal eruption, Im sure they would tell you a lot. the 1967, 1968 and 1969 eruption were very spectacular are the lava fountains of Taal. :)

another strong quake happened in Japan with a magnitude of 7.1 and whose epicenter is located overland at a depth of 10km. localized tsunami alert of 2M was also issued in Japan.

It's coincidental that this quake happened after ACE reported for the last four hours, a significant increase of density in proton/cm3.

just an update. though JMA retained the 7.1 intensity while the USGS has revised the intensity from 7.1 to 6.6.

update on the proton/cm3 density, 30 minutes ago, the density went down from around 13 to about 5: normally, it is observed at about <3. But in the last update, it is now at 21 proton/cm3, a relatively high. we have to note that the ACE satellite that took the measurements is positioned 1 hour before this solar wind will make an impact on the (magnetosphere of the) earth.

great thing about taal is it's not devastating because it is confined inside a lake not like pinatubo, may parents told me they can view taal eruption above tagaytay and watched one of the greatest fireworks in the world provided by nature. :cheers:.

hmmmm, not quite that safe my friend. Yes Tagaytay is the safest place to watch Taal's eruption in 1965-1977 because it sits atop a high ridge but the lake itself doesn't always contain the eruption. And after 1965, only mild to moderate Strombolian eruptions (1966-1977) occurred which only affected the SW part of volcano island.

Mt.Pinatubo is way too far in comparison to Taal. Pinatubo rose to fame as 2oth century's second largest volcanic eruption, with a Volcanic Explosivity Index (VEI) of 6 (the same with Krakatoa 1883 and Tambora 1815), while Mayon is famous as a beautiful perfectly coned shaped volcano with spectacular lava fountains.

Taal is one of the most unique volcanoes in the world that's why its designated as "DECADE VOLCANO". The lake does contain the eruption but in three instances, it created more harm than protection.

in 1754..for 6 months the volcano went into episodes of eruption causing earthquakes and seiches (tsunamis in lakes) that swamped lakeshore towns. then pyroclastic surges and ballistic projectiles buried lakeshore communities with ashes dusting as far as Manila. The eruption and blasting caused subsidence of former lakeshore towns of Tanauan, Taal, Bauan and Lipa.

In 1911, the violent blasts killed all living inhabitants of Volcano Island in an instant and severely devastated the towns of Talisay. Laurel and Agoncillo (a total of 142 square miles area of destruction). These powerful blasts killed a total of 1,335 people and left only 199 injured survivors (in Sitio Gulod, Laurel 116 people died out of 120 inhabitants). Only a few coconut trees and two puppies were left alive on Volcano Island. Ashes reached as far as Manila. Seiches overturned boats of escaping villagers drowning them and those waves coming ashore over the Nothern, Northeast, Western and Southwestern shore of Taal Lake washed entire villages up to 2,500 feet away.

In 1965...tremors and rumblings first occurred on Volcano Island. But everyone was taken by surprise that the eruption blasted out of the southwestern slope of the Main crater, ripping it violently up to the southwest shore of the island. Superheated volcanic material and heavy mud was blasted laterally (called base surges) all over the island and extended to the shorelines of Laurel and Agoncillo. A total of 300 dead and missing people were declared.

As said by Mr. Renato Solidum, long quiescent periods of Taal are usually followed by violent eruptions, especially if it occurs on the main crater, where lakewater makes the eruption more explosive.

:ohno:

On the lighter side...seismic activity in 1991 and 1993 were so alarming that they raised it to Alert Level 3....but the volcano didn't erupt...I hope it would just be like that this time

BTW, PAGASA declared that its already summer.

Sabay kamot sa ulo...summer? Ni wala nga ako masyadong naramdamang init. Parang Disyembre pa rin dito sa Maynila!

just an update. though JMA retained the 7.1 intensity while the USGS has revised the intensity from 7.1 to 6.6.

Reminds me of 2012 movie, no?

vulnerable ba ang Manila sa epekto ng Taal, sakaling pumutok (wag naman sana)??
Ang tanong nga eh, pati rin ba kaya sa Cavite, sa paanan ng dating caldera ng Taal?

BTW, PAGASA declared that its already summer.

Sabay kamot sa ulo...summer? Ni wala nga ako masyadong naramdamang init. Parang Disyembre pa rin dito sa Maynila!

Buti jan di umulan... Here in Cebu it went wild... Strong winds and heavy rains that flooded some city streets...

And its summer, according to PAGASA. :doh:
Oh well, the compensation is: We have La Niña.

It hasn't rained heavily here for more than a month now yet the wind is still dry yet cool.

Ang tanong nga eh, pati rin ba kaya sa Cavite, sa paanan ng dating caldera ng Taal?

well Bernie as we all know, Taal Lake is the caldera itself of the ancient Taal (mega) Volcano and Cavite is its "gentle slope"....so don't ever think of those large magma blobs breaking the lake floor coming in contact with the lake itself...or else...you might consider revising the maps of NCR, Cavite, Batangas and Laguna ^^:nuts:

Laguna de Bai was also considered an ancient caldera, hence the hot springs at Talim Island. Actually, much of Manila and South GMA area are littered with volcanoes, from Bataan at the east, even Corregidor is considered a submereged caldera. Even Makiling, Banahaw nearby are volcanoes...and even the ancient Laguna de Bai.

Anyway, they say that we have a lot to owe to volcanoes and earthquakes for life on earth to be sustained. Scientists said that its better to have a live molten inside than a dead cool core like Mars.

yeah, The Laguna Volcanic Field Complex. but theories are still debatable if either its a single caldera or multiple calderas (Sampaloc Lakes) with surrounding scoria/cinder cones and Thermal Fields with Fumaroles. Or maybe the whole area is dotted with shallow calderas and deepened by local faulting that created its irregular shape.

CAVW (Catalog of Active volcanoes of the World) lists the volcanoes of that area:

Whether multiple or single, one fact remains: The area that we're living here in South Manila is volcanic.

Come to think of it, Mexico City is much closer to volcanoes than Manila does...or is it?

Twenty one (21) volcanic earthquakes were recorded by the seismic network around Taal Volcano (14.0000°N, 120.9833°E) during the past 24 hours. One (1) of these events which occurred at 10:06 A.M. yesterday was felt by residents at Intensity II in Brgy. Calauit. Water temperature at the Main Crater Lake (west-side via Alas-as) slightly increased from 29.8°C to 30.1°C. Gas measurements conducted at Taal Main Crater Lake last January, February and March 2011 yielded carbon dioxide (CO2) emission values of 2,250 tonnes per day (t/d), 1,875 t/d and 4,670 t/d respectively. This large rise in C02 concentration indicates gas release from the magma at depth. Result of the ground deformation survey (precise leveling) conducted around the Volcano Island last 05-11 April 2011 showed that volcano edifice is slightly inflated as compared with the 02-09 February 2011 survey..

Alert Level 2 is hoisted over Taal Volcano with the interpretation that magma has been intruding towards the surface, as manifested by CO2 being released in the Main Crater Lake and increase in seismic activity. Hence, PHIVOLCS advises the public that the Main Crater, Daang Kastila Trail and Mt. Tabaro (1965 -1977 Eruption Site) are strictly off-limits because sudden hazardous steam-driven explosions may occur and high concentrations of toxic gases may accumulate. Breathing air with high concentration of gases can be lethal to human, animals and even cause damage to vegetation. In addition, it is reminded that entire Volcano Island is a Permanent Danger Zone (PDZ), and permanent settlement in the island is strictly not recommended. DOST-PHIVOLCS is closely monitoring Taal Volcano’s activity and any new significant development will be immediately relayed to all concerned.

OMG Japan was struck by a strong earthquake again! Intensity 5! just an hour ago!

^^There's nothing to be surprised about, I say. Japan is already synonymous with earthquakes. But the repercussions of these earthquakes are to watch out for.

Why the frequency of earthquakes in Japan after the 9.0 March 11, 2011 Tohuku Earthquake?

Japanese seismologist says the major quake caused major movements on the trench that re-distributed the stress to different parts of the fault and trenches in Japan. so quakes are now occurring in clusters near the March 11 epicenter, along the same stretch of the trench or to other major faults nearby. Lately we had one in Nagano, one near Niigata and about one to two each in Chiba, Fukushima and Ibaraki Prefectures (closer to Tokyo) ranging 5-7 in magnitude

^^There's nothing to be surprised about, I say. Japan is already synonymous with earthquakes. But the repercussions of these earthquakes are to watch out for.

I see, but somehow these can also have effects too in our faultlines in our country. Sa Ilocos Norte halos weekly na ang moderately strong quakes doon. sunod sunod na talaga ang mga lindol ngayon

I see, but somehow these can also have effects too in our faultlines in our country. Sa Ilocos Norte halos weekly na ang moderately strong quakes doon. sunod sunod na talaga ang mga lindol ngayon

naaah, its just that everybody now is aware of the earthquakes. The faultlines in Japan are independent to the Philippines.

The last major earthquake in Ilocos was in 1983 (The Laoag Earthquake)...its just maybe releasing the built-up stress in years. And there are also years that we are shaken by more moderate to strong earthquakes than the usual.

1990 was really a year of earthquakes

February 8, 1990 - Bohol Quake (and tsunami) - 6.8 M - no deaths
June 14, 1990 - Panay Quake (Culasi, Antique) - 7.1 M - 8 deaths
June 21, 1990 - Manjil-Rudbar Quake (Iran) - 7.4 M - 50,000 deaths
July 16, 1990 - Luzon Quake (Cabanatuan,Baguio)- 7.9 - 1,600 deaths

1999 too:

June 7, 1999 - Bayugan Quake (Agusan del Sur) - 5.6 M - no deaths
August 17, 1999 - Izmit-Golcuk Quake (Turkey) - 7.6 M - 17,200 deaths
September 7, 1999 - Athens Quake (Greece) - 6.0 M - 143 deaths
September 21, 1999 - Jiji, Nantou Quake (Taiwan-ROC) - 7.3 M - 2,415 deaths
December 12, 1999 - Duzce Quake (Turkey) - 7.4 M - 900 deaths


I think in the brighter side of this, with small quakes lately its good we are always on alert and conscious that the Philippines is an earthquake prone country...that keeps us ready at all times :yes:

I agree! Although we couldn't keep these natural forces at bay, we are always forced to be vigilant with what's happening around because it can affect us directly and indirectly.

Year's hottest day recorded in Metro Manila on Tuesday
KIMBERLY JANE TAN, GMA News (http://www.gmanews.tv/story/218760/nation/years-hottest-day-recorded-in-metro-manila-on-tuesday)
04/26/2011 | 06:10 PM

Residents in Metro Manila on Tuesday went through the hottest day so far this year at 36.1 degrees Celsius, state weather forecasters said.

In a phone interview with GMA News Online, forecaster Gladys Saludes said the Philippine Atmospheric Geophysical and Astronomical Services Administration (Pagasa) recorded the hottest temperature in Metro Manila for the year so far at around 3:55 p.m at the Science Garden in Quezon City.

But she said it was even hotter in Tuguegarao in Cagayan province in northern Philippines, where temperatures soared up to 37.8 degrees on Wednesday.

Saludes said that the normal temperature for the month of April was 34.9 degress.

She explained that the wind coming from the Pacific Ocean was warm and moist, making the temperature in the country hotter.

The hottest temperature recorded by Pagasa in Metro Manila last year was 38 degrees.

Past records

The highest temperature in Metro Manila — 38.5 degrees Celsius — was recorded on May 14, 1987.

The highest temperature in the country, meanwhile, was recorded on April 29, 1912, when a sizzling 39.5 degrees Celsius was registered in Tuguegarao City in Cagayan Valley. — RSJ, GMA News

mukhang may chance na ma-hit ng Manila ang 38-degree mark..:shifty:

^^ At least I haven't heard of Manila around 40s--so far.

Ano ba yan?...hehehehe.....record breaking na mamaya ito....remember former record breaker Al Azizi, Libya at 44 degrees celsius under a shade (i forgot the year)...then ours here is around 41 at Tuguegarao ( I also forgot the year)?.......

The Pacific is now going into a neutral season.....naku moist warm Pacific Easterlies....that kinda humid and hot

Kanina, it rained...after the rain, Manila turned into the largest sauna there is! :bash:

yeah, expect the same thru the week...hot and humid with isolated rainshowers until the middle of May.

CNN Report: What will happen to Manila if a major earthquake strikes?
Mon, Mar 14, 2011 8:58 AM PHT
http://beta.ph.news.yahoo.com/happen-manila-major-earthquake-strikes-20110313-175800-959.html

A CNN report released April 2010 documents Manila's earthquake vulnerability...

In the wake of the massive 8.9-earthquake that hit Japan last week, the lingering question now on every Filipino's mind seems to be, "are we next?" And if so, "what will happen to us?"

Since the 7.0-magnitude earthquake struck Haiti in January 2010, local geologists have been anticipating a major earthquake to hit Manila termed as the "Big One."

:gossip:
the huge earthquake that caused devastation in haiti was a 7.0 magnitude. the massive earthquake that hit japan was an 8.9 magnitude. with earthquakes lately becoming more frequent and catasthropic, the announcement of phivolcs that the marikina valley faultline may become active soon can send the mind reeling with brief paralyzing fear due to feelings of utter helplessness in such a situation.

true, the lingering question to many a pinoy's mind right now is, "are we next?" bringing the question home and making it more personal, everyone should be asking: "is my house standing on a faultline?" i think i can help with your answer to the question.

recently, i had a chance to assemble all the valley fault maps of phivolcs and i did it in a way that my edited version can be e-mailed. i also did another assembly of maps wherein the fault trace of the outdated 1999 map of phivolcs is replicated onto google map. the level of detail on this one shows the street names (very clearly) where the faultlines lurk. so if there's a dangerous crack in the earth underneath you, you'll know it outrightly --without a doubt-- when you view the map.

a lot of effort went into my work that it covers the west fault as well as the east fault, and it even identifies all the known subdivisions that sit on these faultlines.

pls. email me at krusnakahoy@gmail.com if you want me to share with you these maps.

as preview, these are the barangays, subdivisions, and other places that have the faultlines running underneath them:

Taal Volcano’s (14.0000°N, 120.9833°E) seismic network recorded twenty-five (25) volcanic earthquakes during the past 24 hours. Field measurements conducted on 05 May 2011 at the eastern sector inside the Main Crater Lake showed that the water temperature increased from 31.5°C to 32.0°C, the water became more acidic with pH value decreasing from 3.09 to 2.94 and the water level further receded to 0.19 meters from the 0.23 meters as compared to the last reading on 19 April 2011. Results of the ground deformation survey (precise leveling) conducted around the Volcano Island last 26-28 April 2011 and 05-11 April 2011 showed that the volcano edifice is slightly inflated as compared with the 02-09 February 2011 survey. Results of gas measurements conducted between 03-04 May 2011at Taal Main Crater yielded a carbon dioxide (CO2) emission rate of 2,057 tonnes per day (t/d). This emission value is down from 4,750 t/d last March 2011, but still higher than the emission rates of 1,875 t/d measured last February 2011.

Alert Level 2 is hoisted over Taal Volcano with the interpretation that magma has been intruding towards the surface, as manifested by the continuing high emission rate of CO2 being released in the Main Crater Lake and sustained seismic activity. Hence, PHIVOLCS advises the public that the Main Crater, Daang Kastila Trail and Mt. Tabaro (1965 -1977 Eruption Site) are strictly off-limits because sudden hazardous steam-driven explosions may occur and high concentrations of toxic gases may accumulate.

Taal Volcano’s (14.0000°N, 120.9833°E) seismic network recorded six (6) volcanic earthquakes during the past 24 hours. One (1) of these events, which occurred at 1:16 P.M. yesterday was felt at Barangay Calauit on the southeastern part of the volcano island at Intensity II accompanied by rumbling sound and two (2) with rumbling sound that occurred at 1:32 P.M. and 1:40 P.M. but not felt. Field measurements conducted on May 13, 2011 at the eastern sector inside the Main Crater Lake showed that the water temperature slightly increased from 32.0°C to 32.5°C, the pH value remained the same at 2.94 and the water level slightly increased from 0.19 meter to 0.21 meter as compared with the reading on May 5, 2011. Results of the ground deformation measurement (precise leveling) conducted around the Volcano Island last 26 April - 03 May 2011 showed that the volcano edifice is still inflated as compared with the 05-11 April 2011 survey. Results of carbon dioxide (CO2) gas emission rates measurement conducted last 03-04 May 2011 at Taal Main Crater yielded a lower value of 2,057 tonnes per day (t/d) as compared with that measured last March 2011 which had a value of 4,750 t/d. However, the obtained value is still higher than the emission rates of 1,875 t/d measured last February 2011.

Alert Level 2 is still in effect over Taal Volcano, with the interpretation that magma has been intruding towards the surface, as manifested by the continuing high emission rate of CO2 being released in the Main Crater Lake and sustained seismic activity. Hence, PHIVOLCS advises the public that the Main Crater, Daang Kastila Trail and Mt.

Tuesday, 17 May 2011 07:25

Mayon Volcano’s (13.2500°N, 123.6833°E) seismic network recorded six (6) volcanic earthquakes during the past 24 hours. Steaming activity was weak to moderate throughout the observation period. Crater glow was observed at Intensity II (can be seen by the naked eye) last night. Results of ground deformation measurement (precise leveling) conducted last 07-11 May, 2011 showed slight inflation of volcano edifice as compared with 06-10 March survey.

Alert Level 1 is still in effect over Mayon Volcano. Although this means that no eruption is imminent, it is recommended that the public should not enter the 6-kilometer radius Permanent Danger Zone (PDZ) due to the continuing threat from sudden small explosions and rockfalls from the upper and middle slopes of the volcano. Active stream/river channels and those perennially identified as lahar prone areas in the southern sector should also be avoided especially during bad weather conditions or when there is heavy and prolonged rainfall. DOST-PHIVOLCS is closely monitoring Mayon Volcano’s activity and any new development will be relayed to all concerned.

The seismic network at Bulusan Volcano (12.7667°N, 124.0500°E) detected a total of one hundred forty four (144) volcanic earthquakes for the past 24 hours. Steaming activity at the active vents was weak to moderate throughout the observation period. Results of ground deformation survey (precise leveling) conducted last 07-11 May 2011 showed no significant change as compared with 01-05 March 2011 survey.

Bulusan Volcano is generally known for its sudden steam- driven or phreatic explosions. Similar events are most likely to occur in view of the volcano’s reactivation last 13 May 2011 especially with the current increase in the volcano’s seismicity. Bulusan Volcano’s status remains hoisted at Alert Level 1, meaning sudden steam and ash explosions can occur.

Entry to the 4-kilometer radius Permanent Danger Zone (PDZ) is strictly prohibited, since the area is at risk to sudden steam and ash explosions. Due to the prevailing wind direction, residents in the northwest and southwest sectors of the volcano are reminded to take precautions against ashfalls. Civil aviation authorities must also warn pilots to avoid flying close to the volcano’s summit as ejected ash and volcanic fragments from sudden explosions may be hazardous to aircraft. If possible aircraft should avoid flying on the western side of the volcano as volcanic debris are likely to be carried in this direction by the prevailing winds. Furthermore, people living near valleys and river/stream channels should be vigilant against sediment-laden stream flows and lahars in the event of heavy and prolonged rainfall. DOST-PHIVOLCS is closely monitoring Bulusan Volcano’s activity and any new significant development will be immediately relayed to all concerned.

ikinababahala ng mga weather analysts ang bagal ng takbo ng bagyo, tapos malakas pa ang gustiness niya. It's gonna be a destructive storm once tumama sa pilipinas

Expect CHEDENG to enhance more of the habagat starting Wednesday....and it might eventually become a supertyphoon off the eastern shore of Isabela and Cagayan Thursday or Friday (forecasted winds of up to 205 kph)

If it reaches 'super typhoon' status and has made significant damage, dapat di na gamitin ang pangalang yan uli...is this the practice of PAGASA?

So Ondoy, Frank and Reming are history, am I right?

Kasi suggestion ko sa PAGASA, eto ang new name, "CHAKA" :colgate:

Hahahahaha!...you mean retire and "decommissioning" of names?

under PAGASA's rules:

if a typhoon incurs a death toll of at least 300 persons and/or is very destructive with at least Php 1 Billion in total damages, its name is retired.

that is independent with the international names of WMO-Northwest Pacific Basin by JMA and RSMC.

list of retired typhoon names since 2001 by PAGASA and their replacements:

HARUROT (2003) - Hanna
UNDING (2004) - Ulysses
VIOLETA (2004) - Vicky
WINNIE (2004) - Warren
MILENYO (2006) - Mario
REMING (2006) - Ruby
FRANK (2008) - to be announced
ONDOY (2009) - to be announced
PEPENG (2009) - to be announced
JUAN (2010) - to be announced (or to be decided pa?)

Do we have a high pressure area existing above the Philippines as of the moment?

nope...

I mean north of PH? The storm is still moving at the same speed, and same direction.

ikr?! i'll give this one 6 more hours before it turns NW

I'll check it by 11AM and lets see.

^^now moving Northwest 2 hours ago...:)

Question:
What is the weather system that affects the movement of the typhoons onto a northeast direction? Usually its above northern Philippines.
