Although tsunamis occur most often in the Pacific Ocean, they can be generated by major earthquakes in other areas.  The most frequent cause of tsunamis…is crustal movement along a fault: a large mass of rock drops or rises and displaces the column of water above it.  This column of water – a tsunami – travels outward from the source at the fantastic speed of 500 mph or more.  When an earthquake occurs in the Pacific Ocean Basin, authorities must quickly decide on a course of action.
