  Indian Ocean - MSN Encarta
Indian Ocean, third largest of Earth's four oceans, bounded on the west by Africa, on the north by Asia, on the east by Australia and the Australasian islands, and on the south by Antarctica.
The ocean narrows toward the north and is divided by the Indian peninsula into the Bay of Bengal on the east and the Arabian Sea on the west.
The average depth of the Indian Ocean is 3,900 m (12,800 ft), or slightly greater than that of the Atlantic, and the deepest known point is 7,725 m (25,344 ft), off the southern coast of the Indonesian island of Java.

 Teachers' Domain: Once and Future Tsunamis
Tsunamis are also blamed for the collapse of the ancient Minoan civilization on Crete.
However, by studying past tsunamis, scientists can predict where they are most likely to occur in the future and what their impact on specific coastal locations is likely to be.
In areas where tsunamis have occurred in the last several hundred years, eyewitness reports or written accounts sometimes provide scientists with the information needed to gauge the potential impact of future tsunamis in the same area.

 MapDig - 2004 Indian Ocean earthquake   (Site not responding. Last check: 2007-10-15)
There were no tsunami warning systems in the Indian Ocean to detect tsunamis or to warn the general populace living around the ocean.
Tsunamis are much more frequent in the Pacific Ocean because of earthquakes in the "Ring of Fire", and an effective tsunami warning system has long been in place there.
In what may be the most significant positive result of the tsunami, the widespread devastation led the main rebel group GAM to declare a cease-fire on December 28, 2004, followed by the Indonesian government, and the two groups resumed long-stalled peace talks, which resulted in a peace agreement signed August 15, 2005.

 The Indian Ocean tsunami and what it tells us about tsunamis in general - January 2005
Tsunamis are the same: since it doesn't push water ahead of it as it crosses the ocean, the energy of a tsunami wave can travel at frightening speeds—up to 800 km/h, which is as fast as a jet plane.
In the middle of the ocean, a tsunami might also be very shallow, perhaps a metre or less in height—you'd never notice it among all the other, taller swells unless you had a sea-level gauge to tell you it was passing by.
From reading the reports of the 26th December 2004 tsunami, one can only gain the impression that the wave front hitting the various countries was many thousands of kilometers long, and the volumes of water huge, which appear to have been much greater than the volume which could have been generated by the original earthquake.

The 2004 Indian Ocean Earthquake was an undersea megathrust earthquake of moment magnitude 9.0 that struck the Indian Ocean off the western coast of northern Sumatra, Indonesia on December 26, 2004 at 00:58:53 UTC (07:58:53 local time in Jakarta and Bangkok).
Tens of thousands were killed by tsunamis of heights of up to 15 m, which flooded coastlines between 15 minutes and 10 hours after the quake, causing one of the deadliest natural disasters in modern history.
Thus Indian Ocean tsunamis are rare; the last major tsunami near Sumatra, on the Indian Ocean side and western end of Indonesia, was caused by the eruption of Krakatoa in 1883.

Despite a lag of up to several hours between the earthquake and the impact of the tsunami, nearly all of the victims were taken completely by surprise; there were no tsunami warning systems in the Indian Ocean to detect tsunamis, or equally importantly, to warn the general populace living around the ocean.
The 2004 earthquake and tsunami seem to be the worst natural disaster since either the 1976 Tangshan earthquake or the 1970 Bhola cyclone, or could conceivably exceed both of these.

 TSUNAMIS OF THE INDIAN OCEAN - by Dr. George Pararas-Carayannis
Although not as destructive as the 26 December 2004 event was, many more tsunamis have been generated by large earthquakes in subduction zones bordering the Indian Ocean and by smaller magnitude events along the Central Indian and Carlsberg mid-oceanic ridges.
Further south on the western side the Indian tectonic plate is bounded by the Central Indian and Carlsberg mid-ocean ridges, a region of shallow seismicity.
Future destructive tsunamis in the region could be generated from earthquakes along the subduction zone off the Makran coast or from a a major thrust fault along parts of deltaic Indus river.

A member of the USGS Tsunami Hazards Assessment project, Morton is also the principal investigator for the USGS National Assessment of Shoreline Change project, which addresses the problem of beach erosion and shoreline change threatening coastal populations and community infrastructures in the United States.
This phenomenon is predicted by models that show tsunami energy wrapping around islands in shore-parallel "edge waves." In Galle, Sri Lanka, unusually high runup heights, nearly 40 ft in some areas, are believed to have been caused by focusing of the tsunami's energy by the sides of a nearby submarine canyon.

 [nhnenews] 2004 Indian Ocean Earthquake Update
The quake and the resulting tsunamis are being called the worst natural disaster in modern history, even though it was not the most deadly, because of the widespread nature of the impact.
The multiple tsunamis struck and ravaged coastal regions all over the Indian Ocean, devastating regions including the Indonesian province of Aceh, the coast of Sri Lanka, coastal areas of the Indian state of Tamil Nadu, the resort island of Phuket, Thailand, and even as far away as Somalia, 4,100?km (2,500?mi) west of the epicenter.
The death toll may be particularly high due to the fact that this is the first time in over 100 years that a tsunami of the Indian Ocean has struck land, leaving the affected countries unprepared and the people unable to recognise the telltale signs of an impending tsunami.

 Indian Ocean Earthquake and Tsunami
Tsunami waves are produced when the seabed is ruptured, causing vertical movement of the water mass in the epicentral region.
Common ocean waves are a kind of surface waves called Rayleigh waves that are confined to the surface layer of the sea and tend to have wavelengths on the order of tens of meters and periods of tens of seconds.
As tsunamis are disasters that can be generated in all of the world's oceans, inland seas, and in any large body of water, any coastal area is at risk from such event.

The 2004 tsunami was the first disaster in recent memory that affected so many countries simultaneously, making it a truly international catastrophe.
Tsunami readiness involves two key components: awareness, which may be improved by educating key decision makers, emergency mangers, and the public about the nature of the hazard (the physical processes involved) and the threat it poses (its frequency of occurrence and impact); and mitigation, which can be improved through pre-event planning.
To establish a stronger link between the ocean research and engineering leadership of Woods Hole Oceanographic Institution (WHOI) and major national and international hazard mitigation programs, WHOI is organizing a colloquium on natural disaster management with a focus on the 2004 Indian Ocean tsunami.
