Sudden internal movements within the earth’s crust below the ocean floor that lead to earthquakes and volcanic eruptions can cause tsunamis.

Explanation:-

A tsunami is a seismic sea wave which is caused by the displacement of a large volume of water, generally in an ocean or a large lake. This displacement can occur because of earthquakes or volcanic eruptions under the ocean floor both of which are categorized as sudden earth movements.
