ABSTRACT Lituya Bay, Alaska is a T-Shaped bay… A tsunami with a record run-up height of 1720 feet occurred in Lituya Bay, Alaska. Perhaps the most famous occurred on July 9, 1958, in Lituya Bay on Alaska’s southeast coast, when a nearby earthquake caused 40 million cubic yards of rock to slide 2,000 feet into the narrow bay. Obviously, megatsunamis will happen again, and possibly without warning. A fishing boat anchored in the cove at lower left was carried over the spit in the foreground; a boat under way near the entrance was sunk; and a third boat, anchored near the lower right, rode out the wave. Differently-aged vegetation is visible on the ridge separating Lituya Glacier from the main part of the bay – looking north from the head of the bay, Lituya Glacier to the right. On July 9, 1958, an earthquake with an estimated magnitude of 7.7-8.3 triggered an enormous rockfall in a remote bay along the Gulf of Alaska. The strong shaking set loose an enormous rockfall, in which 40 million cubic yards of material (9 Superdomes!) The 1958 Lituya Bay earthquake took place on June 9, 1958, on the Fairweather Fault, causing a rockslide of about 40 million cubic yards into the Lituya Bay. This mega-tsunami was triggered by a strong 8.3 earthquake at the Fairweather Fault , which resulted in a huge landslide that fell into the narrow inlet of Lituya Bay. Its super wave reached 1720 feet (524 meters) and destroyed parts of Lituya Bay in Southeast Alaska. The highest wave ever recorded occurred on July 9, 1958 in Lituya Bay, Alaska reaching a height of 524 meters (1,720 feet), 250 feet taller than the Empire State Building.
