On 17 October 2015, a landslide of roughly 60 × 10 6 m 3 occurred at the terminus of Tyndall Glacier in Taan Fiord, southeastern Alaska. Tsunami-inducing landslides are rare but have occurred in Alaska and elsewhere. Vegetation loss is clear near the water line. In October 2015, a massive landslide slid into Taan Fjord and created a tsunami in excess of 600 feet. Researchers have noted another potentially imminent landslide in the Karrat Fjord, says Fritz, where a slow trickle of rocks could turn into abrupt slide. This landslide-generated tsunami had a maximum height of over 600 feet. Fritz adds that the Greenland event is reminiscent of a 1958 tsunami — the tallest ever recorded1 — in Lituya Bay, Alaska. At Taan Fjord in 2015, a landslide caused a tsunami that crested at 600 feet. A research team that visited the site earlier this month found that a large volume of rock had plunged — probably spontaneously — from one of the steep sides of the fjord into the water 1,000 metres below, and shattered chunks of a glacier. Scientists hope studying last month’s deadly event will improve modelling of rockslides that could become more frequent with climate change. The Icy Bay landslide in Alaska. Flow depth here was likely 5 meters based on the height of branches stripped off trees in the background. And in 2017, a landslide in Greenland produced a tsunami that roared into a small, isolated community. More recently, a 2015 landslide near Alaska’s Taan Glacier produced a 633 feet (193 meter) wave in Taan Fjord that smashed into the opposite wall of the glacial valley. I featured this landslide, which was detected via the seismic detection system developed by Goran Ekstrom and Colin Stark, in a blog post at the start of this year. The wave washed away eleven houses, and four people are presumed dead. Approximately 90% of the landslide entered the fjord, generating a tsunami. At Taan Fjord in 2015, a landslide caused a tsunami that crested at 600 feet. What matters in science — and why — free in your inbox every weekday. The landslide flowed into Taan Fjord, triggering a localised tsunami that was detected 155 km away, according to the Lamont-Doherty press release. Tyndall Glacier, the source of the fjord, retreated 10 miles from 1961 to 1991. Both of these events thankfully occurred in sparsely populated areas, so few fatalities occurred. The phenomenon, which occurred in October 2015, was recorded in the Taan fjord in southeastern Alaska and appears to be within the four largest tsunamis recorded in the past century. A very nice video has been posted on Youtube describing the link between the giant Icy Bay landslide in Alaska in 2015 (this landslide is also variously known as the Taan Fjord landslide and the Tyndall Glacier landslide), which is the largest known recent landslide in North America, and the melting of the adjacent glacier. “Landslide-generated tsunamis are much more locally limited than tsunamis produced by sea quakes, but they can be massively tall and devastating in the vicinity,” says Hermann Fritz, an environmental engineer at the Georgia Institute of Technology in Atlanta who led the research team. And in 2015, a landslide-generated tsunami in the Taan Fjord in Icy Bay, Alaska, caused a 300-metre run-up of water, says Synolakis.Â, “Earlier, we didn’t really believe such extremes were possible,” he says. GNS Science has posted a nice video in which Dr Chris Massey explains some of the key features of the landslides, and the work they are doing to try to monitor them: Posted in: The landslide generated a large tsunami that caused extensive damage along the flanks of Taan Fjord. Landsat 8 image of Taan Fiord acquired in 2016. And in 2017, a landslide in Greenland produced a tsunami that roared into a small, isolated community. Geophys. The wave traveled down the fjord, dislocating sediment and … The 2015 Taan Fjord landslide generated a 633 foot high tsunami, for example. And although the tsunami dissipated quickly as it crossed the deep, six-kilometre-wide fjord, it still had enough energy to send water 50 metres up the hillside opposite. Eyewitnesses likened it to an atom bomb explosion; its tsunami’s highest elevation was 524 meters (or 1,720 feet). It was actually discovered in New York City from satellite photos and a large team of scientists was sent out to examine the evidence of this rare and extreme tsunami that tore across Taan Fiord. But more careful examination indicated no significant tectonic activity just before the landslide. The looming tsunami of Harriman Fjord The looming tsunami of Harriman Fjord Icy Bay [near Taan Fjord] was full of glaciers as recently as 100 years ago.” A giant boulder moved by the tsunami as it ran down Taan Fjord. landslide video There you’ll find pictures of the most at-risk dams. A 2015 Taan Fjord slope failure caused a 193-meter (or 633 feet) tsunami. 166, 153–175 (2009). Much of the landslide material was deposited on the Tyndall Glacier and into the fjord. This blog One of the tallest tsunamis in recorded history — a 100-metre-high wave that devastated a remote settlement in Greenland last month — was caused, unusually, by a massive landslide, researchers report.Â. And in 2015, a landslide-generated tsunami in the Taan Fjord in Icy Bay, Alaska, caused a 300-metre run-up of water, says Synolakis. Such information is sorely needed, says Costas Synolakis, a tsunami researcher at the University of Southern California in Los Angeles who was not involved in the Greenland survey. [1] On 9 July 1958, a 7.8 M w strike-slip earthquake in southeast Alaska caused 90 million tonnes of rock and ice to drop into the deep water at the head of Lituya Bay. And a landslide on the west coast of Greenland in 2017 created a wave, initially more than 300 feet high, that destroyed much of a nearby fishing village and killed four people. Required fields are marked *. This landslide-generated tsunami had a maximum height of over 600 feet. Pure Appl. The tsunami wreaked havoc on the small village of Nuugaatsiaq, located on an island within a fjord. In cold, glacial regions, rocks and ice are held together on steep rock sides, and rising temperatures could make these slopes unstable and these events more common. It caused a tsunami that inundated an area over 20 km 2, whereas the landslide debris itself deposited within a much smaller area of approximately 2 km 2. Chunks of glacier shattered when a powerful tsunami ripped through a fjord in western Greenland in June. AGORA, HINARI, OARE, INASP, CrossRef and COUNTER. All Rights Reserved.

He is particularly interested in climate, oceanography, fisheries and the Earth sciences. The Icy Bay landslide in Alaska: a nice video describing the link with glacial melting. The slide was so large that it generated a seismic signal suggestive of a magnitude-4.1 earthquake, confounding initial efforts to identify its cause, says Trine Dahl-Jensen, a seismologist at the Geological Survey of Denmark and Greenland. And in 2017, a landslide in Greenland produced a tsunami that roared into a small, isolated community. Courtesy of Ground Truth Trekking It triggered a megatsunami with an initial height of 100 metres (328 ft) and a run-up on the opposite shore of the fjord of 193 metres (633 ft). “In Taan Fiord (Icy Bay, Alaska), a landslide that began moving slowly decades ago suddenly failed in October 2015.
