Answer 2

A tsunami is a tidal wave that is also referred to as a seismic sea wave.

It is a large number of waves within a water body that happens due to the movement of a large amount of water.

It usually takes place in a large water body like a sea or an ocean.

It can be triggered due to a volcanic eruption, landslide, meteorite impact, earthquake, glacier calving, underwater explosion due to detonation by a nuclear device or any other disturbances under or above water.

Unlike conventional ocean waves, a tsunami happens due to water displacement.
