What happens when there is an earthquake under the sea?

An underwater earthquake creates huge shock waves. These shock waves cause immense tidal waves known as tsunamis.

Tsunamis can travel many thousands of kilometres through the sea, before finally breaking on land. They cause death and destruction, wiping away lives and property mercilessly. In 1992, tsunami washed away two thirds of an entire island in Indonesia. Recently on 26 December, 2004 tsunami waves in the Indian Ocean caused disaster in many countries including India. Originated from Sumatra, it was biggest tsunami disaster ever recorded.
