A tsunami (plural: tsunamis or tsunami; from Japanese: 津波, lit. "harbour
wave";English pronunciation: /suːˈnɑːmi/ soo-nah-mee or /tsuːˈnɑːmi/ tsoo-nah-mee[)
, also known as a seismic sea wave, is a series of water waves caused by the
displacement of a large volume of a body of water, generally an ocean or a large lake.
Earthquakes, volcanic eruptions and other underwater explosions (including
detonations of underwater nuclear devices), landslides, glacier calvings, meteorite
impacts and other disturbances above or below water all have the potential to generate
a tsunami.
