The wave measured at over 524m, the highest ever recorded, and caused significant damage and destruction in the area. Subsequent mathematical modeling at the Los Alamos National Laboratory (Mader, 1999, Mader & Gittings, 2002) supported the proposed mechanism as there was indeed sufficient volume of water and an adequately deep layer of sediments in the Lituya Bay inlet to account for the giant wave runup and the subsequent inundation. August 9, 1958.

[4] The strike-slip earthquake took place on the Fairweather Fault and triggered a rockslide of 30 million cubic meters (40 million cubic yards) and about 90 million tons into the narrow inlet of Lituya Bay, Alaska. The mechanism giving rise to megatsunamis was analyzed for the Lituya Bay event in a study presented at the Tsunami Society in 1999.[17]. Tammy Uzelac Hall, 2018, July 13 ) Lituya Bay is situated 1958 lituya bay, alaska earthquake and megatsunami deaths the near future water in Bay! It seems to be solid, but it was jumping and shaking like crazy. This trimline is 180 feet above sea level and 1000 feet from the high tide mark. TheSunmorehad vanished, andthe Wagners were never found. 11,300 feet up Mount St. Elias, another group of climbers felt the ground moving in waves as avalanches pounded down the slopes around them. After these considerations it was determined that glacial drainage was not the mechanism that caused the giant wave. [20] In particular, the amount of sediment apparently added to the bay, judging by the sea-floor shape, was much greater than could be explained by the rockfall alone, or even the rockfall and sediment disturbed by it, and the energy of the resulting waves from the rockfall and stirred-up sediment would not have been sufficient. English: On 9 July 1958, a rockslide in w:Lituya Bay, Alaska, caused an enormous tsunami estimated at 1,720 feet (524 meters) tall. A subsequent analysis to the 1999 one that examined the wider impact of the event found that the rockfall itself was inadequate to explain the resulting accounts and evidence. Ward and Day describe how the initial rockfall could have triggered a second submarine slide of glacial sediment capable of generating the wave observed in the outer bay. Accessed November 20, 2020. Over the next three weeks, the climbers made the second ascent of Mount Fairweather, a first ascent of an unnamed peak, and had come within 200 feet of the first ascent of Mount Lituya.

Although the earthquake which caused the megatsunami was very energetic and involved strong ground movements, several possible mechanisms were not likely or able to have caused the resulting megatsunami.
