    What do you know about tsunamis? How do they occur?

    Answer:

    When there is an earthquake or volcanic eruption on the ocean floor, enormous waves .known as tsunamis occur. For example on 26th December 2004 the Indian plate went below the Burma plate which caused the rising of the sea waves by several meters. The water withdrew from coastal areas in great quantity and later returned as massive waves to fill in the gaps, towards coastal areas around the Indian Ocean.
