WebTsunamis, also called tidal waves, are the vertical movement of a large body of water. As a consequence of this movement, huge waves are produced driven by a large amount of sustained energy and therefore at high speed. Tsunamis can only occur in seas and oceans, since lakes do not have enough water for their movement to be considered a tsunami. WebBecause of complex interactions with the coast, tsunami waves can persist for many hours. As with many natural phenomena, tsunamis can range in size from micro-tsunamis detectable only by sensitive instruments on the ocean floor to mega-tsunamis that can affect the coastlines of entire oceans, as with the Indian Ocean tsunami of 2004.
