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. Aboard the Badger, Bill Swanson was shaken awake by the earthquake. This 7.8Mw earthquake was characterized as extreme and triggered many rockslides accounting to three million cubic meters that fell into the Lituya Bay from several hundred meters. Scientists who had not seen the effects of the wave firsthand argued that above 300 feet, the soil and trees must have slid into the bay during the earthquake. The 1964 Alaska Earthquake and resulting tsunamis caused the most damage and casualties in the US. Scientists were puzzled for some time by the sheer size of the wave, because they could not identify a mechanism that could have created such a massive reaction. The earthquake triggered a massive landslide into the waters at the head of the bay. [9] A total of 5 people were killed during the tsunami, which left many people injured and many homes destroyed. The wave destroyed the forest over the light areas to a maximum height of 524 meters. Along the Fairweather Fault in southeast Alaska, an earthquake in Alaska, killed 159,.

The recent disaster in Japan demonstrates the incredible destructive power of a megatsunami in a heavily populated area. For most of the bay, destruction below the trimline was absolute. Swanson also claimed to be able to see Lituya Glacier, normally hidden behind the turn the T-shaped bay takes to the northwest. In Gilbert Inlet, which branches north at a right angle from the head of the bay, Miller found that a stream delta had vanished and 1,300 feet of ice had sheared off the end of Lituya Glacier. It was jumping and shaking like crazy, shedding blocks of ice from its face into the water. It caused significant geologic changes in the region, including areas that experienced uplift and subsidence.

The wave that followed ripped spruce from 1,700 feet up a mountain slope and left trimlines in the bay that are visible today. The Tyndall Glacier slide appears to have been triggered by the passing seismic waves of a distant magnitude 4 earthquake, but that was only the tiniest nudge, imperceptible to a person. Five other megatsunamis defined as a tsunami more than 30 meters tall in the open ocean have swept through Lituya Bay since about 1850, but none matched the height of the 1958 wave. Several scientists have since modeled the conditions of that day in Lituya Bay to try to determine what happened. The study concluded that:[17]. Lituya Bay sits on the Southeast side of Alaska.

Tammy Uzelac Hall, . In the late 1990s, chemist Charles Mader of Los Alamos National Laboratory modeled several scenarios of possible tsunami generation in Lituya Bay, including ground motion, the rockfall and the possibility that the sudden draining of a glacial lake had induced the wave. Fritz and Hager found that a slide like the one at Gilbert Inlet could generate that much run-up because the rapid impact of the slide would bring a large air cavity into the water behind it, displacing far more water thanjust the volume of the rock. The wave swept through the main channel at 180 kilometers per hour. Accessed November 20, 2020. The retreats of these glaciers form the present "T" shape of the bay, the Gilbert and Crillon inlets.

They came off the glacier like a big load of rocks spilling out of a dump truck. He confirmed Swansons assertion that the wave originated from the northwestern inlet of the T, where Lituya Glacier spills into the bay; the wave, he said, splashed up the mountain slopes as it came around the corner and spread out as it entered the main body of the bay to a height of about 30 meters. The impact was heard 80 kilometers (50mi) away,[7] and the sudden displacement of water resulted in a megatsunami that washed out trees to a maximum elevation of 524 meters (1,719 feet) at the entrance of Gilbert Inlet. He saw the mountains at the head of the bay shaking and rockslides tumbling down their faces, according to a 1960 U.S. Geological Survey (USGS) report about the megatsunami. [17] The rockfall also caused air to be dragged along due to viscosity effects, which added to the volume of displacement, and further impacted the sediment on the floor of the bay, creating a large crater.

Competing Risk Models In Survival Analysis, [11], The earthquake caused a subaerial rockfall in the Gilbert Inlet. [12], Four or five megatsunamis are believed to have occurred at Lituya Bay during a 150-year period:[17][18]. The giant wave runup of 1,720 feet (524 m.) at the head of the Bay and the subsequent huge wave along the main body of Lituya Bay which occurred on July 9, 1958, were caused primarily by an enormous subaerial rockfall into Gilbert Inlet at the head of Lituya Bay, triggered by dynamic earthquake ground motions along the Fairweather Fault. Some of the material landed on the toe of Tyndall Glacier, but enough of it slammed into the water to generate a megatsunami with 600-foot run-up. The landslide scar, whichwas high above Gilbert Inlet on a near-vertical slope, appeared to have dumped about 40 million tons of rock into the inlet all at once.
