Images of Ocean Floor Show Effects of Tsunami
Iphtashu Fitz writes "This week the UK's Royal Navy presented images taken by the survey ship HMS Scott of the damage to the floor of the Indian Ocean that triggered the tsunami two months ago. The Scott has a high-resolution multi-beam sonar that let it generate highly detailed images of the sea floor, some 200m to 5000m below sea level. An image showing the scale of the damage, and the full presentation made by the Commanding Officer of HMS Scott (38MB PowerPoint) are available. The presentation contains a number of images that have more detail than those available on the websites."

The Royal Navy's survey ship HMS Scott has collected unique images of the Indian Ocean seabed in the vicinity of the devastating tsunami earthquake epicentre.
The work, announced last month by the Ministry of Defence, is being carried out in order to further the understanding of earthquakes and assist prediction of such events in the future. It will be of considerable benefit to the Asia region as a whole and potentially give a global perspective.
HMS Scott's tasking is a non-military role that will provide bathymetric ( measuring the depth of water ) and geological assessment of the Asian earthquake epicentre and extended fracture zone. To assist with this, scientists from the Southampton Oceanography Centre and the British Geological Survey have embarked in the ship.
The depth of water in the vicinity of the epicentre varies between 200m to 5000m which is well within HMS Scott's capability using her high-resolution multi-beam sonar.
The epicentre lies within the Indonesian Exclusive Economic Zone, and the survey itself follows discussions with the Indonesian Government about HMS Scott's potential value in furthering the understanding of the earthquake and future risk prediction. The survey falls under the definition of Marine Scientific Research under United Nations Convention on Law of the Sea (UNCLOS).
Survey imagesHMS Scott's survey will provide the 'base map' for future extensive research into the process of how earthquakes work; this is a crucial moment to conduct such research.
While HMS Scott is not directly involved in the humanitarian relief effort, her survey work in the vicinity of the epicentre is of significance to the scientific community in furthering the understanding of the tsunami.
HMS Scott deployed from the UK in November 2004 in order to undertake a programme of work in the North Atlantic, Arabian Sea and Indian Ocean and is scheduled to return to the UK in June 2005.

The collision has forced up spectacular large thrust ridges up to 1500 m high...
New ridges nearly a mile high?!? Well, that certainly explains the little wave it made...
I'll turn into a supernova and burn up everything. Well I'll turn into a black little hole and you'll turn into string.
The India tectonic plate, one of the most mobile in recent geologic time, slipped underneath the southeast asia one causing a major uplifting, which caused the tsunami. A relatively unusual geologic cause of a tsunami. Original reports where that some areas fell by 2000 ft, which would be quite remarkable and a bit of an exageration.
So long and thanks for all the fish . . . !!!

Bullshit.
Didn't you see the news YESTERDAY where Bush tripled his funding request to Congress for tsunami aid to $950 million?
Oh, wait. You were too busy bashing the U.S. to let a simple thing like hitting news.google.com (where it was a top story in it's category for most of the day) get in your way.

LiveScience report that a new analysis of the December earthquake that caused disastrous tsunami waves to strike Asia and Africa. The report finds it was three times more powerful than earlier measurements suggested. This would make it the second largest earthquake ever instrumentally recorded...
