TSUNAMI

A tsunami or tidal wave as they are popularly known, is a seismic sea wave originating from any one of several submarine geological phenomena, such as volcanic explosions or earthquakes. They travel in the open ocean at speeds up to 640 kmh. On Boxing Day 2004, (the 26th December 2004) an earthquake measuring 9.0 on the Richter Scale occurred under the sea off the coast of Sumatra. The resultant tsunami or tidal waves killed over 125,000 people throughout the entire Indian Ocean area extending from Burma, Indonesia and Malaysia in the east, west to Sri Lanka, India, the Maldives, Somalia, Kenya, Tanzania and the Seychelles.
