The earthquake was from Iran:

Earthquake shakes southern Iran
An earthquake with an initial reading of 6.1 on the Richter scale has struck southern Iran.

The earthquake on Wednesday afternoon was near Bandar Abbas in Hormuzgan province, home to one of Iran's major oil refineries.

The quake may have caused fatalities, the provincial disaster headquarters chief told Reuters news agency.
"All our rescue groups are on alert in Bandar Abbas and [nearby] Qeshm island. We have sent groups to the area. There is the possibility of casualties and fatalities," Yasser Hazbavi said.

The US Geological Survey said the earthquake was 53km west-southwest of Bandar Abbas and at a depth of 55km.

Residents across the Gulf in the United Arab Emirates reported feeling the tremor.

CNN Report on Quake



(CNN) -- A strong earthquake measuring 6.1 in magnitude struck southern Iran on Wednesday, according to a preliminary report from the U.S. Geological Survey.

The epicenter was located about 55 km (35 miles) west-southwest of Bandar e-Abbas, Iran -- which is just across the narrow Strait of Hormuz from Oman.

The tremor could also be felt in Dubai, where CNN staff members said they felt the building they were in shake for about 15 to 20 seconds.

"From my office window at the Dubai Media City where all foreign media are located, I can see that a lot of offices have evacuated buildings," CNN Dubai Bureau Chief Samson Desta said.

"I can see up to perhaps 200 people who have taken refuge out in the streets, causing somewhat of a traffic jam."

There are concerns in Dubai, where there are a lot of high-rise buildings.

Malec is going to make a new thread after it hits 10,000 posts, but i think we should make one when she hits 700.9m

I think they will all happen at about the same time.

Don't have the link but search for 'Burj Dubai channel 5' on youtube, I think it's in 5 parts.

It wasn't a small earthquake. It was 6.2 in Iran and recorded 4.9 in the Emirates. In Dubai Media City I felt it very well, I felt the ground was spinning and swinging but I thought I was dizzy because you don't expect earthquakes in Dubai. Some buildings including The Gate at DIFC are evacuated. I wonder how they felt at the top of Burj Dubai

Especially the man controlling the crane who is by the way technically the highest human on Earth (highest above the ground directly below them and with a support under them, so excluding the people on planes)

Any way that craneman must been scared for his life, I take this more seriously after watching 0:42 of this video: http://www.youtube.com/watch?v=-E_Ii...eature=related

What do you mean they didn't feel anything? The higher you go, the more you feel, without question. There are no dampers or any special systems in this building to absorb the force of an earthquake. So the highest point of this building will have the biggest momentum caused by the earthquake.

Or you are saying the top is swinging all the time anyways so they don't feel the difference?

because the burj dubai is so massive and heavy it simply absorbs the energy of the earthquake, the higher the building the more energy it can absorb

Hi Altin, from SZR today it looked as though a column had been put up, but still only the wheels when you look at the top through binoculars.

I will miss 700m as flying off for a few days again.....crap.

OK you might have a point there, but the force of an earthquake is so massive that it is shaking mountains and land masses maybe a million times bigger than this tower. I don't think you can simply eliminate the effects of an earthquake just by building massive.

When the land below the tower moves, the tower moves as well, otherwise it would tear apart from the ground. When the base moves, the tower should be flexible enough to withstand the earthquake. So it swings. That would be at its maximum on the top. Maybe the building absorbed the vibration, but they were the ones swinging most.

HAHA funny idea but is probaly true and would cost all the money on Earth.

One day human hopefully will be able to lift millions of tonnes of structure all the way out of Earth's atmosphere...

And has the debate about whether or not burj dubai shook during that earthquake today settled yet? I though obviously it would shake to the extent that the habitants inside the building would've felt the building shaking.

absoulutely! The sheer mass of these montrous buildings goes a LONG way in absorbing the energy waves from a quake! In Los Angeles where I live, the buildings downtown (built in the past 30-40 year range) are amongst
some of the safest, buildings in the area. The tallest we have (310m) is rated for up to an 8.5 big one (this big one is expected to be from 2-7 minutes long). If we get hit by this worst case scenario, this will be one of the only buildings still standing, without significant damage. of course it does have a dampening system though - large horzontal struts, and a core that apparently contains 5-10 times the amount of reinforcement when compared to most other supertalls..

it depends on if we are talking about the devastating type of quake that shakes up and down versus side to side.. sway from the side to side quakes does travel up the structures to the top well, if there is no dampning in the building, but the up and down shaking (the most damaging by far) is absorbed in great amounts by structure.
