TSUNAMI IS A JAPANESE WORD ,WHICH means 'harbor waves'. It is a series of water waves caused by the displacement of of a large volume of a body of water ,usually an ocean. Tsunamis are caused by under sea landslides or by 'sea quakes',that is an earthquake whose epicenter lies below the ocean .If the sea bed is displaced up to several meters,the water layer of several kilometer in thickness above it. also moves with it.The waves caused by the movement has a lot of energy- much more than a wave of same height whipped by the wind .This become apparent when the waves moves towards the coast.
In December 2004 ,around ,230,000 people died in a devastating tsunami.But most of Tsunamis do not caused any damage ,as they occur in the sparsely populated pacific area
