    In the open ocean a tsunami is less than a few feet high at the surface,but its wave heightincreases rapidly in shallow waten Tsunamis wave energy extends from the surface to thebottom in the deepest waters.As the tsunami attacks the coastline,the wave energy iscompressed into a much shorter distance creating destructive,live-threatening waves.
    In the deep ocean,destructive tsunamis can be small——often only a few feet or less inheight-and cannot be seen nor can they be felt by ships.But,as the tsunami reachesshallower coastal waters,wave height can increase rapidly.Sometimes,coastal waters aredrawn out into the ocean just before the tsunami strikes.When this Occurs,more shorelinemay be exposed than even at the lowest tide.This major withdrawal of the sea should betaken as a warning of the tsunami waves that will follow.
