tidal wave

tidal wave, term properly applied to the crest of a tide as it moves around the earth. The wavelike upstream rush of water caused by the incoming tide in some locations is known as a tidal bore . In popular usage the term tidal wave also is often applied to any destructive wave or to high water not related to tidal phenomena. These latter waves are of two types: tsunamis , which are waves caused by earthquakes , and storm surges (see under storm ).
