A tsunami is a natural disaster or catastrophic event that occurs in the oceans. It occurs due to many geological process like volcanic eruptions, underwater landslides, asteroids and earthquakes.

In tsunamis the seismic energy generated in the earth crust causes the generation of high tides, which are responsible for huge destruction of the neighboring terrestrial habitat.
