Actually, there have been reports of bubbling in that area shortly after the tsunami. Geologists have been speculating that the tsunami earthquake may have reactivated under sea volcanoes and *another fault line. I don't know much about this at all, but am merely repeating what I remember reading after the tsunami.

I thought it was the same fault line ? But as this is a subduction fault (edge of one plate, typically ocean bed, getting pushed under adjacent plate, typically continental shelf), it makes sense that it is very sensitive area prone to volcanic eruptions: as cool sea-bed rock and a lot of sea-water gets dragged under the crust, it gets very hot, and creates quite an explosive mixture of molten rock and super-heated steam. This is the same situation which has caused the re-birth of Krakatau. By the way, the destructive eruption of Krakatau was preceeded by 3 months of rumblings and fartings.

So, without being alarmist, and accepting that the December 26th events relieved a lot of pressure along the fault, it does seem that this fault is somewhat unstable at the moment, and I can understand how it will take a while for all this displaced material to settle down. I am not a geologist, by the way, just find this interesting, so anyone with more knowledge please tell us.

The USGC states:

Seismologists have observed that for every magnitude 6 earthquake there are 10 of magnitude 5, 100 of magnitude 4, 1,000 of magnitude 3, and so forth as the events get smaller and smaller. This sounds like a lot of small earthquakes, but there are never enough small ones to eliminate the occasional large event. It would take 32 magnitude 5's, 1000 magnitude 4's, 32,000 magnitude 3's to equal the energy of one magnitude 6 event. So, even though we always record many more small events than large ones, there are never enough to eliminate the need for the occasional large earthquake.

I'm sorry, what? Could I have this is layman's terms please ?

The earthquake warning has caused damage to marine tourism in Trang province

The President of the Hotel and Tourism Business Association of Trang (ตรัง) Province, Mr. Mon Sakulmethanon (มนต์ สกุลเมธานนท์), disclosed that earthquake warnings in the last two days had caused damage to marine tourism in the province.

Following several earthquake warnings by the National Disaster Warning Center during March 9th-11th along the Andaman Sea, many tourists have cancelled their trips to Trang Province. He commented that that it would take some time for Thailand to restore tourists' confidence towards local tourism.

Hence, he demanded all units concerned to urgently launch public relations for this season so as to attract tourists to Thailand. He informed that some 46 islands surrounding Trang beach will help prevent impacts from tsunamis.

Strong Quake Rocks Eastern Indonesia
03.14.2006, 02:35 AM

A powerful undersea earthquake struck Indonesia's eastern coast on Tuesday. There were no immediate reports of damage or a tsunami.

The 6.8-magnitude quake was about 60 miles west of Ambon, the capital of Maluku province, the U.S. Geological Survey said on its Web site. It was around 25 miles under the Banda Sea, it said.

Residents in Ambon fled homes and offices when the quake struck, witnesses said.

I'll give it a go ...... First you need to know 2 things

---- 1) earthquakes relieve stress on the crust of the earth .. they have to happen. It takes alot of release of the stress on the crust to keep things from wrecking totally. So above ... we NEED magnitude 6 quakes.

---- 2) The scale ... a one is like taking a toy baby hammer and hittting the ground ... a 2 is like taking an upholstry hammer .... a 3 is like taking a sledge hammmer ... a 4 is like using a pile driver .... a 5 is like dropping a tank out of a plane from a mile up ... etc

So ... we need them! and we need big ones or lots and lots and lots of little ones! All the mountains in the world that were NOT formed by volcanos directly ... were formed by plate tectonics and similar events ... earthquakes relieve the stress on the plates ... so no earthquakes and we could have a new mountain range spring up some place inconvenient!


Guys please help me out if I made any basic mistakes!
