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. WebTsunamis arrive at a coastline as a series of successive crests (high water levels) and troughs (low water levels) - usually occurring 10 to 45 minutes apart. As they enter the shallow waters of coastlines, bays, or harbors, their speed decreases to about 50-60 km/h. For example, in 15 m of water the speed of a tsunami will be only 45 km/h.
