A tsunami is an ocean wave
with a long period of duration that is formed by an
underwater earthquake or landslide, or volcanic eruption.
It may travel unnoticed across the ocean for thousands
of miles from its point of origin and builds up to great
heights over shallower water. Also known as a seismic
sea wave, and incorrectly, as a tidal wave. |
