Was that photo taken from atop Mt. Apo, or of Mt. Apo from a distance?

This should kill any misconceptions that Legazpi city is a dangerous place when Mayon erupts:

[olineil]

Ive found this website that has video clips of mayon eruption, some are quite big and it will give u a good idea how mayon erupts and How it feels to be in Legazpi when mayon erupts:

Disaster Management Plan

Metro model for tsunami workshop

IN THE MIDDLE OF THE NIGHT, a strong earthquake (magnitude 7.9) stirs the Manila Trench, releasing shock waves from beneath the South China Sea. You felt the shock as you were taking in the sights and sounds at the Baywalk, the al fresco dining strip along Roxas Boulevard.

Don’t wait for the sisig you ordered or for the folk singer to finish his set. You have only an hour to seek higher ground or be swept away by four-meter high waves!

This is a tsunami impact “model” for Manila -- one example of several disaster scenarios deduced by the Philippine Institute of Volcanology and Seismology (Phivolcs) in a bid to make the most accurate and, hopefully, life-saving assessment of our own experiences to giant killer waves.

The data analysis leading to these scenarios is called tsunami numerical modeling, the subject of a 10-day international workshop hosted by Phivolcs in Quezon City that opened yesterday.

“We cannot predict earthquakes but we can speculate on the impact,” Phivolcs Director Rene Solidum told reporters.

With grim images from the Dec. 26, 2004 Indian Ocean tsunami still vivid, Solidum said data acquired through tsunami modeling is crucial in devising early-warning procedures and evacuation plans, especially for coastal communities.

From a model, which can be done on a per-area basis, the public may learn the expected “arrival time” of a tsunami after an earthquake of certain strength, apart from most vulnerable locations, the estimated height of the waves upon hitting the coast, and the extent of the inundation or flooding.

According to Solidum, a sample model Phivolcs has prepared for the City of Manila gives the following cause-and-effect equation:

If an earthquake occurs somewhere along the Manila Trench, a magnitude of 7.9 is enough to generate a wall of water as tall as two to four meters by the time it enters Manila Bay.

The first wave is expected to crash on land in about “one hour” from the time of the quake, and can cause devastation at the North and South Harbors, recreational and commercial strips facing Manila Bay, and squatter colonies lining the coast.

A tsunami originating from the South China Sea is actually expected to lose considerable speed by the time it enters the bay, thanks to the bay’s narrow opening formed between the Bataan peninsula and Cavite, Solidum explained.

The last recorded tsunami to hit Manila was caused by a magnitude 6.5 temblor that struck at 7:25 p.m. on June 3, 1863.

Fortunately, the sea then rose merely by less than a meter and nobody was reported killed, the Phivolcs director said.

The agency has also come up with a tsunami model for Infanta, Real and Nakar, coastal towns of Quezon facing the Pacific Ocean.

The Phivolcs’ target is to have models covering the entire Philippine coastline.

The workshop runs until Nov. 19, with the cooperation of the International Tsunami Information Center in Hawaii.

Participants came from developing countries in the Southeast Asia, Pacific, Indian Ocean regions, namely China, Fiji, India, Indonesia, Madagascar, Malaysia, Mauritius, Papua New Guinea, Singapore, Sri Lanka, Vietnam and the Philippines

---------------------------------------------------------

Therefore, after a strong earthquake, you have at most 1 hour to run to higher grounds away from the bay. The workshop failed to mention the specific higher ground areas.
You will know firsthand when a tsunami is going to happen. Once the water on the Bay area recedes or appears like draining away after a strong earthquake, it will flow back to shore as a high wave at least twice.

I thought there really was an earthquake that struck Metro Manila!

[bustero]

So much for that sisig.

[amras]

kinabahan ako dun ah...

[ThisFire]

I just found out today. I hope everyone's alright!

[OtAkAw]

I did not know this! There was not even a single news!

[ramvingar]

hehe, guys, check out the date of the first post. it's last year pa. sandrin just posted a news article that's why this thread got bumped up. but yeah, kinabahan din ako for about 5.34 seconds.

[normandb]

di ko naramdam yong earthquake.

[thomasian]

tangerks!!! last year pa yung quake sa MM.

[c0kelitr0]

can someone close this thread?!
