Tsunami is Japanese for "harbor wave". A tsunami is caused by the displacement of a massive amount of water in an ocean, sea or large lake, as from an earthquake or an impact event. Upon impact, rather than being seen as a large ocean wave like popularly known break waves on shorelines, the water "rolls" in akin to a rising tide with a wall of water flooding everything inward.
