What a Tsunami Is |
|
Tsunamis, commonly called tidal waves by the general public, are large sea waves or surges. These waves can carry a lot of energy from one side of the globe to the other, reeking havoc where ever they make landfall, and as shown by the December 26, 2004 SE Asian event, tsunami's can claim thousands of lives and cause millions of dollars worth of damage to property. The United States Geological Survey defines tsunami as: "A sea wave of local or distant origin that results from large-scale sea floor displacements associated with large earthquakes, major submarine slides, or exploding volcanic islands" http://earthquake.usgs.gov/4kids/eqterms.html#tectonic |
