8.4 Earthquake reported near the coast of Libya ?

The National Institute for Earth Physics has reported an earthquake of 8.4 degrees in Libya NEAR COAST OF 19.05.2011, 14:49:02 (UTC)
Anybody else hear about it depth 30 km

...would be something in probably the gigaton range. The biggest bomb ever exploded was 50 megatons, which would, according to Wikipedia, equal the energy output of an 8.35 earthquake.


However, I think to get the full energy of that bomb put into an earthquake the bomb would have to be buried several miles underground before detonation. The 50 Mt bomb got a seismic rating of about 5.5.

You'd need a bomb 10,000 times more powerful going off to get a 9.5 or so. 500 gigatons, which I can't even imagine how many thousands of miles that airborne shock wave would destroy cities.

Hell, the 50 Mt bomb smashed brick houses flat 35 miles away and was breaking windows over 550 miles distant!

just checking DU rules

They usually are up to date

saying it was 8.4 in Libya

just a bunch of chatter out there

PB

is not being honest about the earthquake reports

I was checking if anybody heard about it

Every college big enough to have a geology dept. has a seismograph.

Good grief. There are extremely competent scientists all over the world - and it does not require advanced degrees.

And there are journalists and citizens who report things that crash and break.

that report on quakes around the world...

Nope, hiding a quake would not be easy.

Hey speak of a TEST!

:) :think:

:evilgrin:

in fact if anyone's noticed there seems to be a lot of activity right at Fukushima (seismically) since the quake

and it is shown as a 5.8 in Japanese sources

5.9-magnitude earthquake has rocked western Turkey, shattering windows,damaging old buildings in one town and killing two people, authorities say. The Istanbul-based Kandilli Observatory said the quake in Kutahya province occurred at 11.15pm (6.15am AEST today) and was centred in the town of Simav.

ANKARA, Turkey, May 19 (UPI) -- A moderate earthquake hit western Turkey late Thursday, rattling buildings in Istanbul and causing one collapse, officials said.

At least two deaths were linked to the quake, Today's Zaman reported. Both victims died of heart attacks, and the newspaper said another man was reported to have died after jumping from a window.

About 50 people were reported injured.

The U.S. Geological Survey reported the earthquake measured 5.8. Earthquakes in that range can cause heavy damage to poorly constructed buildings near the epicenter.

Notice where the North African Plate and the European Plate are... just the boundary. (North of Libya crossing the Med)

? whoops

is that Santorini WAS Atlantis... and that by in the Aegean.



You can see the edge of the volcano caldera in that map.

(Call me a geek for some reason I like to keep up with crap like that)

Could the numbers have been transposed when the inital report went out? 4.8/8.4?

And a 4.9 can be felt 150 miles away (nearest large Libyan town - Tobruk, but there are a few smaller ports closer that could have some damage if they weren't built well...)
