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. The epicenter of the quake was at latitude 58.37N, longitude 136.67W near the Fairweather Range, 7.5 miles (12.1km) east of the surface trace of the Fairweather fault, and 13 miles (21km) southeast of Lituya Bay. The Lituya Bay megatsunami took place on July 9, 1958 and caused 5 deaths. Earthquake is of high or moderate magnitude typically over magnitude four. On July 9, 1958, an earthquake with a magnitude of 8.3 on the Richter scale rocked a small inlet in Alaska called Lituya Bay. Several scientists have since modeled the conditions of that day in Lituya Bay to try to determine what happened. On July 10, 1958, a magnitude 7.7 earthquake occurred on the Fairweather Fault in southeast Alaska. Incredibly, however, the Erdie also survived the wave, likely carried up over the southern shore of the bay before the backwash sent it back into the bay. A giant wave generated on July 9, 1958, by a rockslide from the cliff at the head of the bay (background, left) destroyed the forest over the light areas to a maximum altitude of 1,720 feetand to a maximum distance of 3,600 feet in from the high-tide shoreline at Fish Lake (foreground, left). August 9, 1958. 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. To Miller, the destruction he saw was clearly the work of a giant wave, but its height seemed unbelievable. A flying boat dropped Paddy Sherman's mountaineering expedition at Lituya Bay on June 17, 1958. The wave that followed ripped spruce from 1,700 feet up a mountain slope and left trimlines in the bay that are visible today. Description. Our tsunami inundation mapsinclude landslide tsunami scenarios for some of Alaska's most at-risk communities, showing which areas are likely to be safe and which are not. [10] Lituya Bay is an ice-scoured tidal inlet with a maximum depth of 722 feet (220m). We develop seismic policies and share information to promote programs intended to reduce earthquake-related losses. June 17, 1958, a magnitude 7.7 earthquake occurred on the north shore from! 2 . Calamity struck at 10pm on July 9, 1958, when a 8.-Richter-scale earthquake rammed the Alaskan coast up and northward. At about 10:15 p.m. on July 9, 1958, a magnitude-7.5 earthquake occurred on the Fairweather Fault, displacing the ground by more than 6 meters horizontally and 1 meter vertically. The Mega-Tsunami of July 9, 1958 in Lituya Bay, Alaska. Of 2.4 miles, triggered by an earthquake triggered a giant wave that destroyed a native village and drowned people! Still, living with the danger of megatsunamis is part of the cost of working and playing in one of the world's most breathtaking landscapes. They flew over rafts of logs fanning out in the open water as far as five miles from the mouth of the bay. 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. Few weeks after the 1958 earthquake and Lituya Bay on June 17 1958! He tossed a life preserver to his 7-year-old-son, told him to pray, and then let out all of his remaining anchor chain. [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. ,Sitemap,Sitemap Description. The earthquake was so strong, and the tsunami came so quickly, that there was not time to get to a safe place. 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. 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. Any copying, redistribution or retransmission of any of 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. Two other boats also were anchored in the bay that night; those four people managed to ride out the wave. UA is committed to providing accessible websites. At approximately 10:15 PM Pacific Time, a magnitude 8.3 earthquake struck the Fairweather Fault in Southeast Alaska triggering a massive landslide that caused 30 million cubic metres of rock and ice to fall into the narrow inlet of Lituya Bay. They felt the quake and watched as an 800-foot stretch of the island's beach disappeared into the bay along with three of their friends. The strike-slip earthquake took place on the Fairweather Fault and triggered a rockslide of 40 million cubic yards (30 million cubic meters and about 90 million tons) into the narrow inlet of Lituya Bay, Alaska. Suzanne Somers Recipes, The trimline slopes down to the right, across scars of slides that occurred before the 1958 earthquake. (Image: Geology.com/NASA Landsat) 5 people were killed in the 1958 Lituya Bay, Alaska earthquake and megatsunami. Incredibly, the altimeter read 1,800 feet1,300 feet higher than the 1936 trimline. The tide was ebbing at about plus 1.5 m and the weather was clear.

After the initial wave, Ulrich said, smaller waves continued to roil the bay for half an hour, reflected back and forth by the shorelines. Propagation of the tsunami wave produced by the 1964 M9.2 earthquake. It caused significant geologic changes in the region, including areas that experienced uplift and subsidence. Citadel: Forged With Fire Mutants, Tonight's M4.9 earthquake at 9:56pm rattled the Interior, with felt reports from Fairbanks, North Pole, Salcha, Nenana, Healy, Cantwell, Delta Junction, Chugiak, Anchorage, and as far south as Victoria, British Columbia. This tsunami is analogous to the tallest ever recorded tsunami, which hit Lituya Bay, Alaska in 1958. Western States Seismic Policy Council 1958 Lituya Bay . Sunmore. [10] It is possible that a good amount of water drained from the glacial lake through a glacial tunnel flowing directly in front of the glacier, though neither the rate of drainage nor the volume of water drained could produce a wave of such magnitude. 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. Lituya Bay Lituya Bay, Alaska, July 9, 1958 Its over 1,700-foot wave was the largest ever recorded for a tsunami. It inundated five square miles of land and cleared hundreds of thousands of trees. The region, including areas that experienced uplift and subsidence land and cleared hundreds of thousands trees! Only the outermost mile of coast had scattered stands of surviving trees. Lituya Bay's Apocalyptic Wave - NASA SURVIVING THE BIGGEST WAVE EVER By DAVE KIFFER - SitNews The strike-slip earthquake took place on the Fairweather Fault and triggered a rockslide of 40 million cubic yards (30 million cubic meters and about 90 million tons) into the narrow inlet of Lituya Bay, Alaska. 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. The wave destroyed the forest over the light areas to a maximum height of 524 meters. By 9pm they were in the air, leaving behind three fishing boats that had come into the steep-walled bay for the night. prohibited. 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. [6] The shock was felt in southeastern Alaskan cities over an area of 400,000 square miles (1,000,000km2), as far south as Seattle, Washington, and as far east as Whitehorse, Yukon, Canada. The wave was a powerful reminder of the forces nature can unleash. University of Alaska (2018, July 13) 60 Years Ago: The 1958 Earthquake and Lituya Bay Megatsunami. The giant tsunami and the unusual geometry of the bay combined to produce the largest wave run-up ever recorded deluging the steep forested hills along the edges of the bay to a height of 524 meters. The site of the mountaineers' camp was scoured down to bedrock. Suzanne Somers Recipes, The northeast wall of Gilbert Inlet in August 1958 shows the scar of the rockslide that generated the megatsunami.

Credit: U.S. Geological Survey. The landslide impacted the water at high speed generating a gian. At approximately 10:15 PM Pacific Time, a magnitude 8.3 earthquake struck the Fairweather Fault in Southeast Alaska triggering a massive landslide that caused 30 million cubic metres of rock and ice to fall into the narrow inlet of Lituya Bay. The glaciers that once carved the central channel have since retreated to the head of the bay, where the crossbar of the T runs parallel to the Fairweather Fault, a strike-slip fault that divides the North American and Pacific plates. Prevention Web (2020, March 26) The tallest tsunami wave ever recorded killed only 5 people. There is an ongoing debate in scholarly circles regarding whether the megatsunami was a result of the rockfall generated by the earthquake, or a result of the earthquake itself. Landslides in Lituya Bay in Southeast Alaska following a magnitude 7.8 earthquake on the Fairweather Fault produced a megatsunami with 1,720 feet of run-up. 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 glacier, lightened, rose before stabilizing in the water, and a large amount of trapped infill (subglacial and proglacial sediment) that was trapped under the glacier and had already been loosened by the earthquake was released as an almost immediate and many times larger second slide. [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.
