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. One hundred and seventeen (117) people died in Turkey's zmir Province while an additional 1,034 . 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.

On July 9, 1958, an earthquake (7.9 to 8.3 on the Richter scale) struck Alaska, shaking off a 90 million (long) ton block of rock and ice into Lituya Bay in southern Alaska, resulting in the biggest wave ever recorded. A long and narrow Inlet with steep cliffs created a local tsunami that washed away much. 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. 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. 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.

A hundred miles up the coast, in Yakutat Bay, a couple was heading home in a skiff after picking berrieson Khantaak Island. [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. The 1958 Lituya Bay earthquake occurred on PST with a moment magnitude of 7.8 to 8.3 and a maximum Mercalli intensity of XI ( Extreme ). 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 feet and to a maximum distance of 3,600 feet in from the high-tide shoreline at Fish Lake (foreground, left).A fishing boat anchored in the cove was carried over the spit in the foreground . They are each about 12 miles (19km) long and 1 mile (1.6km) wide with an elevation of 4,000 feet (1,200m). C. Volcanic Eruptions (volcanogenic tsunami) 1. Like Paddy Sherman's climbers and the fishermen who survived the wave, it helps to be lucky. Unfortunately, there was nothing anyone could have done to prevent any of the five deaths. 2; p. 267-29 Tocher, Don, and Miller, D.J, 1959, "Field .

Shore, from southwest of Gilbert Inlet to La Chaussee spit occur again in Gulf. 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 picked up the Badger and tossed the boat across the spit and out of the bay. Education is our best tool. Though no deaths were recorded, the size was noteworthy. 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 feet and to a maximum distance of 3,600 feet in from the high-tide shoreline at Fish Lake (foreground, left).A fishing boat anchored in the cove was carried over the spit in the foreground . But a record-breaking tsunami of a different sort occurred in 1958, in a remote part of Alaska known as Lituya Bay and was witnessed by only six people, two of whom died. [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). 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. [12], The wave made its way to his boat 23 minutes after he saw it and carried the Edrie down to the southern shore and then back near the center of the bay. It must have risen several hundred feet. Instead of a cascade of impacts, the falling rock struck the bay like an asteroid instantaneously and as a single, massive object. [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. As the waves calmed, Ulrich piloted through the debris and made a harrowing escape through the shallow entrance at around 11pm. From there itraced towardthe mouth of the bayand the fishing boatswith some side-to-side sloshing that accounted for variations in the height of the trimline along the length of the bay. The shores of the bay are densely forested except for visible trimlines, swaths of shoreline laid bare, with trees hundreds of meters high on the shores, and nearly 2 meters in diameter, sheared off at their bases by the force of the water. The major earthquake that struck on the Fairweather Fault had a Richter scale reading of 7.9 - 8.3 and a maximum perceived intensity of XI (Extreme. 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. 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. 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. After the initial wave, Ulrich said, smaller waves continued to roil the bay for half an hour, reflected back and forth by the shorelines. The front of Lituya Glacier is at the lower left corner. It seems to be solid, but it was jumping and shaking like crazy. July 9, 1958, a magnitude 7.7 earthquake occurred on the island Bay a few weeks after the Mega-Tsunami Epicenter was 8 miles east of Salcha, with a depth of 2.4 miles thousand.! [9] A total of 5 people were killed during the tsunami, which left many people injured and many homes destroyed. 132 subscribers Alaska Earthquake Science Fact: "In 1958, a magnitude 7.8 earthquake created a landslide into Lituya Bay that generated a megatsunami wave reaching 524 m (1,720 ft). But Miller had seen driftwood and rocks strewn across the slopes at the top of the trimline, and the trees that had not been washed into the bay all lay on the ground pointing westward, as the wave had traveled. 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. At that point, Ulrich told Alaska Sportsman in 1958, he sent a radio distress call to let his wife know that he and his son were lost. The earthquake caused a subaerial rock fall in the Gilbert Inlet. The seven miles long and two miles narrow. The 1958 Lituya Bay Mega-tsunami was the second largest in recorded history, caused by a magnitude 7. In other words, 60 years after the Lituya Bay tsunami, we are still working out how it happened. By 9pm they were in the air, leaving behind three fishing boats that had come into the steep-walled bay for the night. The two had gone out on the water at 20:00 hours PST and when the earthquake hit, the resulting rocking of his boat woke Ulrich up. I know you can't ordinarily see that glacier from where I was anchored. A total of five people were killed in the event: three people died on Khantaak Island at the mouth of Yakutat Bay when the beach they were standing on subsided 100 feet below sea level; the other two died when their boat was sunk by the tsunami at Lituya 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. 100-million-ton slide onto the Lamplugh Glacier, generate a megatsunami with 600-foot run-up, residents had no warning before the wave arrived, Lituya Bay Case: Rock Slide Impat and Wave Run-Up, The Alaska Earthquake of July 10, 1958: Movement on the Fairweather Fault and Field Investigation of Southern Epicentral Region, The 1958 Lituya Bay Landslide and Tsunami - A Tsunami Ball Approach, 2156 Koyukuk Drive, PO Box 757320, Fairbanks, AK 99775.
