<P> A tsunami ( from Japanese : 津波 , `` harbour wave '' ; English pronunciation : / tsuːˈnɑːmi / tsoo - NAH - mee ) or tidal wave , also known as a seismic sea wave , is a series of waves in a water body caused by the displacement of a large volume of water , generally in 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 . Unlike normal ocean waves which are generated by wind , or tides which are generated by the gravitational pull of the Moon and Sun , a tsunami is generated by the displacement of water . </P>
