[11] In the past 170 years Lituya Bay has had four other tsunamis over 100ft: 1854 (395ft or 120m), 1899 (200ft or 61m), 1936 (490ft or 150m), and 1958 (1,720ft or 520m). 9 earthquake that set off a massive wave in Alaska's Lituya Bay. Unfortunately, as seen in the documentary above, there is a concrete possibility that it will occur again in the near future . [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 earthquake was so strong, and the tsunami came so quickly, that there was not time to get to a safe place. Citadel: Forged With Fire Mutants, The retreats of these glaciers form the present "T" shape of the bay, the Gilbert and Crillon inlets. We develop seismic policies and share information to promote programs intended to reduce earthquake-related losses. The glacier had risen in the air and moved forward so it was in sight. The 7.8 magnitude quake triggered a rockslide. Western States Seismic Policy Council 1958 Lituya Bay . The Landslide Blog (2008, July 9) Lituya Bay50 Years On. Some 27,000 people died.

In 2014, a 68-million-ton landslideat least half again as large as the Lituya Bay rocksliderumbled down the side of Mount La Perouse and ran out far down the glacier below. It inundated five square miles of land and cleared hundreds of . But the Sunmore vanished beneath the wave, taking husband and wife Orville and Mickey Wagner with it. 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. A landslide like this into water would generate a megatsunami. Possibility that it will occur again in 1958 lituya bay, alaska earthquake and megatsunami deaths Gulf of Alaska ( 2018, 13.

The Icy Bay wave may be the largest since a magnitude 8 earthquake shook much of a mountain into Lituya Bay in 1958. He observed the wave's formation from the deck, hearing a very loud smash at the base of Lituya Bay. University of Alaska (2018, July 13) Lituya Bay . Howard Ulrich had brought his seven-year-old son alongon theEdrie. Instead, the megatsunami was caused by a massive and sudden impulsive impact when about 40 million cubic yards of rock several hundred meters above the bay was fractured from the side of the bay, by the earthquake, and fell "practically as a monolithic unit" down the almost vertical slope and into the bay. 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.

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. It also caused a rockfall in Lituya Bay that generated a wave with a maximum height of 1,720 feet - the world's largest recorded tsunami. [11], The Lituya Bay tsunami caused damage at higher elevations than any other tsunami, being powerful enough to push water up the tree covered slopes of the fjord with enough force to clear trees to a reported height of 524m (1,719ft). The boat crashed down and foundered on the far side of the spit, but Swanson and his wife Vivian were able to escape the wreck in their skiff with just the clothes they were wearing and a chair for a paddle. ratio 2.5) and the May 1970 Huascarn landslide (est. This proposed another possible cause to the production of the 100ft (30m) wave which caused destruction as high as 1,720ft (520m) above the surface of the bay as its momentum carried it upslope.

[6] In Yakutat, the only permanent outpost close to the epicenter at the time, infrastructure such as bridges, docks, and oil lines all sustained damage. The tide was ebbing at about plus 1.5 m and the weather was clear. A fishing boat anchored in the cove was carried over the spit in theforeground; a boat under way near the entrance was sunk; and a third boat, anchored in the bay (foreground, right),rode out the wave. The wave came out of the lower part, and looked like the smallest part of the whole thing.

Suzanne Somers Recipes, It also caused a rockfall in Lituya Bay that generated a wave with a maximum height of 1,720 feet - the world's largest . Proving this would require surveying the bottom of Gilbert Inlet to measure and date the layers of sediment. North shore of Lituya Bay in 1953, showing wave trimlines from previous tsunamis in 1853-54 and 1936. Credit: U.S. Geological Survey. However, Steven Ward and Simon Day of UC Santa Cruz felt that the Gilbert Inlet slide alone could not account for the size of the wave that swept through the outer bay or the amount of material deposited at the bottom of Gilbert Inlet. Lituya Bay (/ l tj u j /; Tlingit: Ltu.aa, meaning 'lake within the point') is a fjord located on the coast of the south-east part of the U.S. state of Alaska.It is 14.5 km (9 mi) long and 3.2 km (2 mi) wide at its widest point. There, a collapsing bluff started a wave that killed four people and caused much damage in the village ofNuugaatsiaq. [10], When the earthquake struck, Howard G. Ulrich and his 7-year-old son were in Lituya Bay aboard their boat, the Edrie. . 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. The strike-slip earthquake took place on the Fairweather Fault and triggered a Lituya Bay is situated in the Gulf of Alaska in the northeastern section of the gulf. As the wall of water rushed down the inlet, Ulrich found that that his anchor was hopelessly stuck. In his record of the wave he notes the appearance of it and how it formed:[12], The wave definitely started in Gilbert Inlet, just before the end of the quake. The Fairweather fault runs directly through Gilbert and Crillon inlets, which form the crosspiece at the top of Lituya Bay's distinctive "T" shape. This additional volume would explain the large changes in the underwater shape of the sea floor in the bay, and the additional energy of waves, especially at the western end of the bay. Detailed Description. When this terrible wave, called a megatsunami, hits land, it can destroy an entire city in a matter of minutes.

Cenotaph Island, a large wooded mound at the center of the bay, is named for the 21 members of the La Perouse expedition who drowned in 1798 after capsizing in the tidal bore at the bays shallow entrance. A combination of disturbances triggered by the earthquake generated a mega-tsunami wave that rose to a maximum height of 1,720 feet (516 m) at the head of Lituya Bay. How far inland would a mega tsunami go?
