[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. Lituya Bay has a history of megatsunami events, but the 1958 event was the first for which sufficient data was captured and was responsible for the deaths of 5 people.[9][19][17].

The mountains were shaking something awful, with slide of rock and snow, but what I noticed mostly was the glacier, the north glacier, the one they call Lituya Glacier. 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. Opposite this scar, on the spur that forms the corner between Gilbert Inlet and the main part of the bay, pilot Kenneth Loken flew alongside a sharp new trimline below which the trees and earth had been stripped away to clean bedrock. .

They flew over rafts of logs fanning out in the open water as far as five miles from the mouth of the bay. When Miller returned to study the effects of the wave, he measured the highest trimline more precisely at 1,720 feet. Six years later, the magnitude 9.2 Great Alaska earthquake would trigger landslide tsunamis across southern Alaska, accounting for many of the deaths from that earthquake. In Turkey & # x27 ; s zmir Province while an additional 1,034 Wikipedia < /a Detailed. Aboard the Badger, Bill Swanson was shaken awake by the earthquake.
