NO DESTRUCTIVE WIDESPREAD TSUNAMI THREAT EXISTS BASED ON

HISTORICAL EARTHQUAKE AND TSUNAMI DATA.

HOWEVER - EARTHQUAKES OF THIS SIZE SOMETIMES GENERATE LOCAL

TSUNAMIS THAT CAN BE DESTRUCTIVE ALONG COASTS LOCATED WITHIN

A HUNDRED KILOMETERS OF THE EARTHQUAKE EPICENTER. AUTHORITIES

IN THE REGION OF THE EPICENTER SHOULD BE AWARE OF THIS

POSSIBILITY AND TAKE APPROPRIATE ACTION.

[toggerob]

Thankfully doesn't look substantial enough to create a Tsunami anything larger than a foot locally. However Port Vila has been roughed up from this. At the close of tourist season I'm expecting the foreign agencies to be on the wires asap. http://en.wikipedia.org/wiki/Port_Vila

[john pike]

The tsunami waves will probably be higher than the initial 32 cm as written earlier. The tsunmi has ended in all these areas while writing. We know that islanders in Vanuatu tend to autoevacuate very fast to higher ground . 19 minutes will probably be enough to get to higher ground in Efate and other places.

waves look higher than originally said

however still does not look too bad

this is a big list and all fairly big

lets hope we do not see a bigger quake happen here

[Crepuscular Ray]

The 7.0 is - so far - likely the be the main shock, and the others of less magnitude would be precursers. Hopefully the 7.0 is going to be the biggest.

Edit, sorry, talking tosh as I hadn't spotted the 7.5 earlier in the day. I still hope that activity there subsides, though.

Unfortunately, there will be bigger earthquakes in this region and beyond in my opinion.

^^^^^^^

As there have been before in the 4.6 billion years this planet has been around in one form or other, and there will be in the future. Your point is? Not really the point of this thread but there will be bigger earthquakes (laws of statistics and geology mean that that's a shoo-in) but which of your various theories does this feed into?

[Snowyowl9]

Yes just spotted this in Vanuata double 7.0+ with a 5.9 aftershock from the first then a powerful 7.5 so that makes it the most significant since March 11th but no harm done as far as we know,but there was severe shaking reported.

There was a small tsunami of 3.4 feet

The BGS said earthquakes were a common event in the west Highlands but added that to have four on the same day was "slightly unusual".

CNN -- A moderate 5.3-magnitude earthquake that rattled southern Colorado early Tuesday morning was the largest to hit the state in more than 40 years, the U.S. Geological Survey said

http://www.cnn.com/2....html?hpt=us_c2

Edited August 23, 2011 by yamkin

[toggerob]

What the msm isn't picking up on is that the 5.3 happened 1/4 mile upstream from the Trinidad dam just close to Long's Canyon on the map. Had the quake struck directly under the dam itself no doubt there'd be some concerned faces right now.
