The tide was ebbing at about plus 1.5 m and the weather was clear. Lituya Bay ma ok. 11,3 km dÅugoÅci i 3,2 km w najszerszym miejscu. The wave started for us right after that and I was too busy to tell what else was happening up there. A further event that erased the above evidence and uprooted trees over 150 meters (492 feet) up the sides of the bay, in 1936. On July 9, 1958, an earthquake caused a landslide in the Gilbert Inlet at the head of the bay, generating a massive megatsunami which had sufficient energy to run up the hill slope just opposite of the landslide to a height measuring 1,722 feet (525 m), taller than the Empire State Building. The giant waves of Lituya Bay An Alaska Science Forum article by Ned Rozell. This proposed another possible cause to the production of the 100 ft (30 m) wave which caused destruction as high as 1,720 ft (524 m) above the surface of the bay as its momentum carried it upslope. It was as though the forests âhad been cut cleanly with a razor blade,â he noted in his log. Exploring Alaska's Lost Coast: Backpacking and Packrafting from Yakutat to Lituya Bay, 2015. U.S. Coast and Geodetic Survey FIELD ENGINEERS BULLETIN no. The third boat, the Edrie, crewed by father and son the Ulriches, was anchored at the opposite side of the bay entrance. The glacier had risen in the air and moved forward so it was in sight. Sand boils and fissures occurred near the coast southeast of there, and underwater cables that supported the Alaska Communication System were cut. [11], At 22:15 hours PST on July 9, 1958, which was still daylight at that time of year, an earthquake with a magnitude of 7.8 struck the Lituya Bay area. Simulation of the Lituya Bay tsunami generated by the 1958 Alaska earthquake. 32 3/4in. Bølgen styrtede ned mod den modsatte kystlinje og løb op ad skråningen til en højde af 1720 fod og fjernede træer og vegetation hele vejen. [3], The bay is known for its high tides, which have a range of approximately 3 m (9.8 ft). After the earthquake it was observed that a subglacial lake, located northwest of the bend in the Lituya Glacier at the head of Lituya Bay, had dropped 100 ft (30 m). The bay is south of Yakutat and Dry Bays and is a remote part of Glacier Bay National Park and Preserve. [8][9], Lituya Bay is a fjord located on the Fairweather Fault in the northeastern part of the Gulf of Alaska. [5] Lighter damage was also reported in Pelican and Sitka. The modeling reproduced the documented physical observations of runup. After these considerations it was determined that glacial drainage was not the mechanism that caused the giant wave. Tsunami-inducing landslides are rare but have occurred in Alaska and elsewhere. [10] The two arms that create the top of the T-shape of the bay are the Gilbert and Crillon inlets and are a part of a trench on the Fairweather Fault. The impact generated a local tsunami that crashed against the southwest shore⦠remember this is still used and is sold as is. When it reached the open sea, however, it dissipated quickly. The name of the bay means âlake within the pointâ in the local Tlingit language. Twenty-one of his men perished in the tidal current in the bay. I can't help it if they don't believe me.

[10], Around five megatsunamis are believed to have occurred at Lituya Bay during a period of about 150 years:[9][14], The mechanism giving rise to megatsunamis was analyzed for the Lituya Bay event in a study presented at the Tsunami Society in 1999.[9]. It is a T-shaped bay with a width of 2 miles (3 km) and a length of 7 miles (11 km). In the past 150 years Lituya Bay has had three othe⦠Den højeste bølge, der nogensinde er registreret, var en lokal tsunami, udløst af et jordskælv og stenfald, i Lituya Bay, Alaska den 9. juli 1958. 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. This earthquake had been the strongest in over 50 years for this region: the Cape Yakataga earthquake, with an estimated magnitude of 8.2 on the Richter scale, occurred on September 4, 1899. That was six miles away and they still looked like big chunks. Lituya Bay is an ice-scoured tidal inlet with a maximum depth of 722 feet (220 m). 1500 pieces. Damage from the 1958 megatsunami appears as the lighter-colored areas on the shores where trees have been stripped away. It was as though the forests âhad been cut cleanly with a razor blade,â he noted in his log. It is 14.5 km (9 mi) long and 3.2 km (2 mi) wide at its widest point. Zatoka. Lituya Bay, Alaskaâs âTsunami Alleyâ Lituya Bay, seven miles long and two miles wide, is situated on the Fairweather coast of Alaska, and is the first inlet north of Icy Strait and Glacier Bay, providing the only secure anchorage for more than 100 miles in the Gulf of Alaska ⦠buyer pays $17.75 s/h. Hohe Gebirgsketten bilden ihre Grenze landeinwärts. The smaller Cascade and Crillon glaciers and the larger Lituya Glacier all spill into Lituya Bay, which is a part of Glacier Bay National Park and Preserve. The two arms that create the top of the T-shape of the bay are the Gilbert and Crillon inlets and are a part of a trench on the Fairweather Fault. C'est le point de départ réel de mon roman "Lituya Bay". i have counted the pieces and they are all present. It must have risen several hundred feet. That went on for a little while—it's hard to tell just how long—and then suddenly the glacier dropped back out of sight and there was a big wall of water going over the point. It is 14.5 km (9 mi) long and 3.2 km (2 mi) wide at its widest point. This mega-tsunami was triggered by a strong 8.3 earthquake at the Fairweather Fault, which resulted in a huge landslide that fell into the narrow inlet of Lituya Bay. [5] In Yakutat, the only permanent outpost close to the epicenter at the time, infrastructure such as bridges, docks, and oil lines all sustained damage. One of the prettiest places in Southeast Alaska has felt some of natureâs most violent behavior. âLituya Bay, Gulf of Alaskaâ by E.W. "At least one and possibly two waves" between 1854 and 1916, based on photographic evidence. La vague, qui a atteint une altitude de 525 mètres, a tout emporté sur le rivage de la bai⦠[citation needed]. Fields denoted with an asterisk (*) are required . 2006. i am willing to answer any questions as best that i can. La baie Lituya, en anglais Lituya Bay, est un fjord des États-Unis situé dans l'Alaska du Sud-Est, sur la côte de l'océan Pacifique. [10] Two people from a fishing boat died as a result of having been caught by a wave in the bay. This was the largest earthquake in Alaska since the quake in Yakutat, near Lituya Bay, in 1899. The 1958 Lituya Bay earthquake occurred on July 9 at 22:15:58 with a moment magnitude of 7.8 and a maximum Mercalli intensity of XI (Extreme). I know you can't ordinarily see that glacier from where I was anchored. 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. The bay was noted in 1786 by Jean-François de Lapérouse, who named it Port des Français. 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. [11] In the past 150 years Lituya Bay has had three other tsunamis of over 100 ft: 1854 (395 ft or 120 m), 1899 (200 ft or 61 m), and 1936 (490 ft or 150 m). A 2010 model examined the amount of infill on the floor of the bay, which was many times larger than that of the rockfall alone, and also the energy and height of the waves. Big chunks of ice were falling off the face of it and down into the water. This incident was the first direct evidence and eyewitness report of the existence of megatsunamis.[4]. Neither water drainage from a lake, nor landslide, nor the force of the earthquake itself led to the megatsunami, although all of these may have contributed. Updated 7/10/2015: Introduction: Map Cenotaph Island is located roughly in the middle of the bay. 10, December 1936. âAlaskan Super Wave â Mega Tsunamiâ from BBCWorldwide YouTube channel, posted August 18, 2008, retrieved January 6, 2018. They are each about 12 miles (19 km) long and 1 mile (1.6 km) wide with an elevation of 4,000 feet (1,200 m). The epicenter of the quake was at latitude 58.37° N, longitude 136.67° W near the Fairweather Range, 7.5 miles (12.1 km) east of the surface trace of the Fairweather fault, and 13 miles (21 km) southeast of Lituya Bay. It is a T-shaped bay with a width of 2 miles (3 km) and a length of 7 miles (11 km). If one likens the shape of Alaska to a bearded human face in profile, Lituya Bay is somewhere near the Adamâs apple. The retreats of these glaciers form the present "T" shape of the bay, the Gilbert and Crillon inlets. When he first encountered Lituya Bay in 1786, the French explorer Jean-François de Galaup La Pérouse was intrigued by an odd line in the forests that surrounded the narrow fjord in southeastern Alaska. Twenty-one of his men perished in the tidal current in the bay. [12][13], Near the crest of the Fairweather Mountains sit the Lituya and the North Crillon glaciers. [9] 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. [7] This is the largest and most significant megatsunami in modern times; it forced a re-evaluation of large-wave events and the recognition of impact events, rockfalls, and landslides as causes of very large waves. 1 talking about this. The debris released was estimated by the study as being between 5 and 10 times the volume of the initial rockfall, a bulking ratio comparable with that of other events such as the September 2002 Kolka-Karmadon rock ice slide (estimated ratio between 5 and 10), the November 1987 Parraguirre landslide (est. The second boat (the Badger) was carried across the la Chasseuse, spit into the ocean, hit by a floating log and sunk but not before its occupants (a married couple, the Swansons) in spite of injuries, managed to board a skiff ultimately to be rescued. It seems to be solid, but it was jumping and shaking like crazy.

It caused significant geologic changes in the region, including areas that experienced uplift and subsidence. Lituya Bay es un fiordo ubicado en Fairweather Fault en la parte noreste del Golfo de Alaska .Es una bahía en forma de T con un ancho de 2 millas (3 km) y una longitud de 7 millas (11 km). ratio 4). Elle fut découverte en 1786 par l'explorateur français Jean-François de La Pérouse. They came off the glacier like a big load of rocks spilling out of a dump truck. Over the last century, at least two landslide-generated tsunamis over 500 feet have occurred in Alaskaâs Taan Glacier in 2015, and Lituya Bay in 1958, which launched a 1,700-foot wave up the opposite slope of the valley. In 1786, for example, French explorer Jean-François de Galaup La Pérouse lost two boats and 21 ⦠[11] Over 30 million cubic meters of rock fell from a height of several hundred meters into the bay, creating the megatsunami. Scientists concluded that there had been a "dual slide" involving a rockfall which also triggered a release of 5 to 10 times its volume of sediment trapped by the adjacent Lituya Glacier, a ratio comparable with other events where this "dual slide" effect is known to have happened. x 22 1/2in. M/V Lituya Service Area: Ketchikan - Metlakatla Shuttle Ferry The Lituya is a shuttle ferry for the Alaska Marine Highway System, built by Conrad Shipyards in Morgan City, Louisiana in 2004. Lituya Bay Lituya Bay is a fjord located on the coast of the south-east part of the U.S. state of Alaska. It is 14.5 km long and 3.2 km wide at its widest point. One boat (the Sunmore) was sunk by the wave and debris as it attempted to exit the bay, and the two people on board (a married couple, the Wagners) were killed. 10, December 1936, World's Biggest Tsunami: The largest recorded tsunami with a wave 1,720 feet (520 m) tall in Lituya Bay, Alaska, History of Lituya Bay, Tsunami and Laperouse (in French), Giant Waves in Lituya Bay, Alaska; USGS PP 354-C, https://en.wikipedia.org/w/index.php?title=Lituya_Bay&oldid=1002596399, Bays of Hoonah–Angoon Census Area, Alaska, Articles using infobox body of water without alt, Articles using infobox body of water without pushpin map alt, Articles using infobox body of water without image bathymetry, Wikipedia articles with WorldCat-VIAF identifiers, Creative Commons Attribution-ShareAlike License. People shake their heads when I tell them I saw it that night. 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. The impact was heard 50 miles (80 km) away,[6] and the sudden displacement of water resulted in a megatsunami that washed out trees to a maximum elevation of 1,720 feet (524 meters) at the entrance of Gilbert Inlet. 1958 Lituya Bay, Alaska earthquake and megatsunami, "Don J. Miller, Giant Waves in Lituya Bay, Alaska", E. W. Eickelberg, Lituya Bay, Gulf of Alaska. Eickelberg, US Coast and Geodetic Survey Field Engineers Bulletin no. Die Bucht hat eine Länge von rund 15 Kilometer und ist etwa 3,2 Kilometer breit. Lituya Bay offers the only sheltered anchorage for a long stretch of Southeast Alaska coast, but the bay itself is hardly safe. At the head of Lituya Bay, Alaska, on July 10, 1958, an earthquake of magnitude 7.3 triggered a gigantic rock fall, later estimated as measuring forty million cubic yards, at the headland of the bay and a resultant 1,700-foot-high tsunami wave because of the water that was displaced. you are bidding on lituya bay, alaska - complete - puzzle. The same topography that leads to the heavy tidal currents also created the tsunami with the highest runup against a hillside in recorded history. Lituya Bay is a fjord located on the Fairweather Fault in the northeastern part of the Gulf of Alaska. The study concluded that, instead, a "dual slide" event was more likely – the rockfall, impacting very close to the head of the Lituya Glacier, caused around 400 meters (1,312 feet) of ice from the glacial toe to break off (as shown in photographs from the time), and possibly injected considerable water under the glacier. On July 10, 1958, a magnitude 7.7 earthquake occurred on the Fairweather Fault in southeast Alaska. GIANT WAVES IN LITUYA BAY, ALASKA By DoN J. MILLER ABSTRACT Lituya Bay, on the northeast shore of the Gulf of Alaska, is an ice-scoured tidal inlet with a maximum depth of 720 feet and a sill depth, at the narrow entrance, of only 33 feet. 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 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. box is excellent. It also caused a rockfall in Lituya Bay that generated a wave with a maximum height of 1,720 feet â the worldâs largest recorded tsunami. The study concluded that:[9]. I know the glacier is hidden by the point when you're in Anchorage Cove, but I know what I saw that night, too. Oblique aerial photograph of Lituya Bay in the summer of 1958. When he first encountered Lituya Bay in 1786, the French explorer Jean-François de Galaup La Pérouse was intrigued by an odd line in the forests that surrounded the narrow fjord in southeastern Alaska. ratio 2.5) and the May 1970 Huascarán landslide (est. A water tower collapsed, and a cabin was damaged beyond repair. La baie Lituya est un fjord situé aux États-Unis, en Alaska du Sud-Est, à 30 km au sud du Mont Fairweather.. Événements antérieurs. This page was last edited on 13 February 2021, at 10:54. [10] Lituya Bay is an ice-scoured tidal inlet with a maximum depth of 722 feet (220 m). This page was last edited on 25 January 2021, at 04:51. There were three fishing boats anchored near the entrance of Lituya Bay on the day the giant wave occurred. ceaco. The bay was noted in 1786 by Jean-François de Lapérouse, who named it Port des Français. [5] The shock was felt in southeastern Alaskan cities over an area of 400,000 square miles (1,000,000 km2), as far south as Seattle, Washington, and as far east as Whitehorse, Yukon, Canada.[11]. Lituya Bay (Alaska) Please provide your name, email, and your suggestion so that we can begin assessing any terminology changes. La baie est notamment célèbre pour avoir été le théâtre en 1958 d'un des plus importants tsunamis provoqué par un glissement de terrain. [10], The wave caused damage to the vegetation up the headlands around the area where the rockfall occurred, up to a height of 520 metres (1,710 ft), as well as along the shoreline of the bay. The earthquake caused a subaerial rockfall in the Gilbert Inlet. The narrow entrance of the bay has a depth of only 33 feet (10 m). The giant wave of Icy Bay The Icy Bay landslide on October 17, 2015 was larger than the amount of rock and soil that slid at Lituya Bay, but the Lituya Bay wave was larger because it fell from a higher elevation into deeper water. Lituya Bay is a fjord located in Glacier Bay National Park and Preserve on the outer coast of Southeast Alaska, about 100 miles (161 km) northwest of Sitka and 69 miles (111 km) west-northwest of Gustavus, Alaska. [3], Lituya Bay is also famous for four recorded tsunamis, in 1854, 1899, 1936, and 1958.[4][5]. [11], The major earthquake that struck on the Fairweather Fault had a moment magnitude of 7.8 and a maximum perceived intensity of XI (Extreme) on the Mercalli intensity scale. A subsequent analysis that examined the wider impact of the event found that the rockfall itself was inadequate to explain the resulting accounts and evidence. Based on Swanson's description of the length of time it took the wave to reach his boat after overtopping Cenotaph Island near the bay's entrance, the wave may have been traveling 120 mph (190 km/h). 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. The narrow entrance of the bay has a depth of only 33 feet (10 m). This mass of rock plunged from an altitude of approximately 3000 feet (914 meters) down into the waters of Gilbert Inlet (see map below). Die Lituya Bay ist eine Meeresbucht an der nördlichen Pazifikküste in Alaska.. Sie befindet sich im Glacier-Bay-Nationalpark im Süden des Bundesstaates. 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. Guinness World Records 2006: 84. The paper's authors suggest that core samples may show a 70-meter (230-foot) deep layer of reworked sediment if this model is correct. En 1958, dans la baie de Lituya, en Alaska, s'est produit un gigantesque tsunami de plus de 500 m! Guinness World Records Ltd. (2005). I don't mean it was just hanging in the air. The father, Howard, turned the boat to face the wave, which picked her up, snapped her anchor chain, carried her above the trees but then washed her back into the bay with no major damage. 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 bayâs shallow entrance. Lituya Bay is a place where Mother Nature has always had the upper hand. [15] 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. NajwiÄksza gÅÄbokoÅÄ zatoki to 219 m, lecz samo ujÅcie do Zatoki Alaska mierzy zaledwie 9,7 m gÅÄbokoÅci i okoÅo 500 m szerokoÅci. [11] Even if a large enough drainage were to take place in front of the Gilbert Glacier, the run-off would have been projected to be on the opposite side in Crillon Inlet. La bahía de Lituya es una entrada de marea fregada por el hielo con una profundidad máxima de 220 m (722 pies). Lituya Bay has a history of megatsunami events, but the 1958 event was the first for which sufficient data was captured at the time. The bay was noted in 1786 by Jean-François de Lapérouse, who named it Port des Français. It is a long, narrow, T-shaped, glacier-carved notch about eight miles long and two miles wide (13km by 3km), bordered on its west end by the Fairweather mountain range. Anchored in a cove near the west side of the entrance of the bay, Bill and Vivian Swanson were on their boat fishing when the earthquake hit:[10], With the first jolt, I tumbled out of the bunk and looked toward the head of the bay where all the noise was coming from. The entrance is considered dangerous to navigation, especially when the tidal currents are running, but the interior of the bay provides good protection to anchored ships. Lituya Bay is a fjord located on the coast of the south-east part of the U.S. state of Alaska. Lituya Bay (/lɪˈtjuːjə/; Tlingit: Ltu.aa,[1] meaning 'lake within the point')[2] is a fjord located on the coast of the south-east part of the U.S. state of Alaska. La baie Lituya. William A. Swanson and Howard G. Ulrich provided accounts of what they observed. Lituya Bay, on the Pacific coast about 100 miles southeast of Yakutat and 40 miles west of Glacier Bay, is the site of the largest splash wave ever recorded. The entrance of the bay is approximately 500 m (0.31 mi) wide, with a narrow navigable channel. Its super wave reached 1720 feet (524 meters) and destroyed parts of Lituya Bay in Southeast Alaska. Lituya Bay is a fjord located on the Fairweather Fault in the northeastern part of the Gulf of Alaska. On the night of July 9, 1958, an earthquake along the Fairweather Fault in the Alaska Panhandle loosened about 40 million cubic yards (30.6 million cubic meters) of rock high above the northeastern shore of Lituya Bay. Miller, Don J., 1954, "Cataclysmic Flood Waves in Lituya Bay, Alaska", "Tsunami rocked Alaska's Lituya Bay in 1958". One example is the log of. 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. The bay (spelled "Latuya") is mentioned in Jack London's short story, "The Unexpected". Tidal currents in the entrance reach 9.4 km/h (5.1 kn). A fine little book about Lituya Bay, a stunningly beautiful nook of sea, ice, rock and rainforest just north of Glacier Bay Alaska on the pacific coast in southeast Alaska.
