WORLD’S BIGGEST TSUNAMI

Biggest tsunamiThe largest recorded tsunami was a wave 1720 feet tall in Lituya Bay, Alaska.

On the night of July 9, 1958 an earthquake along the Fairweather Fault in the  Alaska Panhandle loosened about 40 million cubic yards (30.6 million cubic meters) of rock high above the  northeastern shore of Lituya Bay. This mass of rock plunged from an altitude of  approximately 3000 feet (914 meters) down into the waters of Gilbert Inlet (see map below). The  impact generated a local tsunami  that crashed against the southwest shoreline of  Gilbert Inlet. The wave hit with such power that it swept completely over the spur  of land that separates Gilbert Inlet from the main body of Lituya Bay. The wave then contiuned down the entire length of Lituya Bay, over La Chaussee Spit and into the Gulf of Alaska. The force  of the wave removed all trees and vegetation from elevations as high as 1720 feet  (524 meters) above sea level. Millions of trees were uprooted and swept away by the wave. This is the highest wave that has ever been known.
