What are the Causes of Tsunamis?

Earthquakes account for about 75% of tsunamis, and about 10% have unknown
causes.

A tsunami is a type of natural disaster that consists of large waves in a
body of water, and it can be the result of any event that creates
underwater disturbances. The most common causes of tsunamis are earthquakes
on the floor of bodies of water, which account for about 75% of all
tsunamis. Landslides, in which land moves down into water and pushes the
water away from the land, are thought to be responsible for about 8%, and
volcanic activity is estimated to cause around 5% of tsunamis. One of the
least common causes of tsunamis is meteorological events, which account for
less than 2% of these disasters. About 10% of all tsunamis have an
undetermined cause.
