Thailand will prepare evacuation plans for tourists and residents on the southern coast hit by the 2004 tsunami following a series of underwater tremors in the Andaman Sea.
"The situation is worrying and we want to alert local authorities and people so that they can prepare for an evacuation" if a big quake strikes, said Samit Thammasarot, the head of the National Committee on Natural Disaster Warning.
"More quakes could cause a major eruption of underwater volcanos, and that could trigger a tsunami again," he said Sunday, urging people living on the Andaman coast to be cautious.
But Samit said the government so far had no plans to issue an evacuation order.
The committee said that between March 9 and 12 it had detected 39 quakes ranging in magnitude from 4.0 to 5.3 near the Andaman Islands, some 500 kilometers (300 miles) west of the southern Thai province of Ranong.
The epicenter of the quakes was located 20 kilometers (12.4 miles) below the seabed, the same depth as the 2004 Indian Ocean earthquake which triggered the killer tsunami that left more than 220,000 people dead in several countries.
In Thailand alone, the tsunami killed some 5,400 people. After the disaster, the government developed an early tsunami warning system in cooperation with neighboring countries and the Pacific Tsunami Warning Center in Hawaii.
"I can assure (people) that we are closely monitoring quakes and will issue warnings if we detect something strong like the tsunami. Our warning system is working well. We have been preparing for that," Samit said.

personally i think that the amount of dies in tsunami raising 500000 victims  I believe that you are right there. It is well known that real number of victims in Thailand alone is far higher than the official numbers. #49

Disaster warning center affirmed earthquakes in Andaman during this period will not cause tsunamis
The National Disaster Warning Center has affirmed in an announcement that yesterday's earthquake in the Andaman did not cause tsunamis. 31 earthquakes have occurred between March 9th and 10th. Two quakes occurred yesterday, a 4.9 Richter magnitude quake at 11.47 am and a 4.6 Richter quake at 5.39 pm. After additional analysis of information and the geological structure of the Andaman Sea, the center believe the frequent quakes will not cause tsunamis that may affect the lives and assets of people along Thailand's Andaman coast. It thus asked that people in the 6 west coast provinces not to panic and carry on their normal living, and also follow up on news from the National Disaster Warning Center.

Ranong quake rumor denied
The National Disaster Warning Center or NDWC denied rumors on Saturday of a major earthquake in the Ranong area. The rumors that circulated over the weekend stated that a quake of magnitude 7.5 on the Richter scale took place near Ranong . Patrawan Tuamlee of the NDWC said that this was not the case. She did say, however, that there had been a slew of temblors in the Andaman Sea, centered around an area some 210 kilometers southeast of Port Blair in the Andaman & Nicobar Islands, and 300km west of Ranong. The situatioon is being watched closely by the NDWC, she added. K. Patrawan said that the NWDC recorded 31 tremors of magnitude 4.1 to 5.3 in a 48 hour period which is “abnormal”. She also asked fishermen and others on the water to report any strange maritime phenomena by calling Tel: 1860. Chumnong Chitpukdee, Director of the Southern Meteorological Center (West Coast), told the Gazette, “I have listened to the NDWC reports, and the quakes that have occurred will not affect Phuket". But, "Our staff are monitoring the situation around the clock", he added. Source: The Phuket Gazette on Saturday #51

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. #53

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. Source: Thai National News Bureau Public Relations Department - 13 March 2006 #56

Close call. Hope everyone is ok there.
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. #57

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 ?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! |
