A long high giant wave caused by earthquakes or volcanic eruption under the sea. Tsunami waves do not dramatically increase in height. But as the waves travel inland But as the waves travel inland, they build up to higher and higher heights as the depth of the ocean decreases. The speed of tsunami waves depends on ocean depth rather than the distance from the source of the wave. Tsunami waves may travel as fast as jet planes over deep waters, only slowing down when reaching shallow waters. While tsunamis are often referred to as tidal waves.
