What is a tsunami?
Often improperly called "tidal waves," tsunamis or seismic sea waves are usually caused by earthquakes that occur near or under the ocean. These waves created by the shifting of the ground creates an intense energy that can result in a destructive wave that can cause damage to a region hundreds or thousands of miles from the tsunami's source.Hawaii is quite vulnerable to tsunamis so the islands have a comprehensive warning and alerting system.
