A tsunami can cross the ocean as fast as a jet
Over deep water, tsunami waves may travel as fast as jet planes, slowing only when they reach the shallows.

A tsunami is a series of waves caused by earthquakes or undersea volcanic eruptions. Its speed depends on the depth of the ocean, not on how far it has come.
