World’s Tallest Tsunami

Today in 1916 – First cargo submarine to cross Atlantic arrives in US from Germany carrying synthetic dyes, drugs and mail. Bet you didn’t know there was such a thing as a ‘merchant submarine’ or that the US bought goods smuggled out of Germany in WW I past the French and British blockades.

Today in 1958 – Lituya Bay, Alaska is hit by a mega-tsunami caused by an earthquake-induced landslide. The wave is recorded at 524 meters high, making it the largest wave in history. That is 1720 freaking ass feet high!!!!

World’s Tallest Tsunami

A tsunami with a record run-up height of 1720 feet occurred 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 force of the rockfall 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 continued 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.
