Researchers say a large landslide and tsunami that occurred in the Bute Inlet area back in November has provided them with a once-in-a-lifetime opportunity. The landslide, which was triggered by heavy rainfall, occurred on the South Interamerican highway. [19], Just what triggered the 1965 landslide remains unclear; the two so-called earthquakes were likely too small to trigger the slide[20] and thus the seismic events were more likely caused by the impact of the landslide masses on the opposite valley wall. [15], British Columbia Highways President Josh Gaglardi attended the scene and directed the construction of a temporary tote road over the southern portion of the slide. The South Nation River landslide (16-17 May 1971) occurred at a site 48 km east of Ottawa and involved nearly 28 ha of debris, which was carried upstream and downstream, filling nearly 2.5 km of the riverbed to a depth of 11 m. Most of the massive scar on the mountain face remains bare rock, without significant growth of trees or other large vegetation. Report on exploration in the southern portion of British Columbia; Geological Survey of Canada, Report of Progress, 1877-1878, Part B. pp. Although this landslide occurred about 50 million years ago, it was so large that weathering, erosion, and volcanic activity have not yet obscured all of the evidence. 2014 Malin Landslide. Scientists say the force of the event was equivalent to a magnitude 4.9 earthquake — and was about one-sixth the size of one of Canada's biggest landslides in 1965 near Hope B.C. This blog Such comparison reveals that the largest landslides on Earth mainly occur below sea level. Changes in groundwater condition, often a trigger for landslides, is not thought to have played a role in the Hope Slide as the slide occurred during a protracted period of sub-zero temperatures in the winter, though some have suggested that freezing of seepage exit points may have caused an increase in water pressure at the toe of the slide.[21]. Despite the risks in the landslide … The Malin landslide claimed the lives of over 150 villagers in the Malin village … Alberta, 1903: A miner’s cottage is buried in rubble after 82 million tonnes of rock came pouring down Turtle Mountain, devastating the small coal-mining town of … Copy link. Johnson Peak was the site of a previous smaller prehistoric rock-slide. Landslides . Two earthquakes were said to have been recorded in the general area of the slide. Landslides can range widely in speed, from very slow to dangerously rapid. Naturkatastrophe The Hope Slide – Der größte Erdrutsch in Kanada | The biggest landslide in Canada - … The blocky and flow-like surface morphology of the deposits suggests rapid emplacement from subaerial sources. The same earthquake caused the infamous tsunamis that obliterated large parts of the Hawaiian ... April 27, 1975 Description: An undersea landslide caused a tsunami in the Kitimat Inlet of northern British Columbia’s Douglas Channel. Bruce, I., Cruden, D.M., 1977. Map of northern British Columbia showing locations of large, long-runout landslides between 1973 and 2003. Recent Landslides, 5 (4), 445-455. Proposed landslide classification. Although this landslide occurred about 50 million years ago, it was so large that weathering, erosion, and volcanic activity have not yet obscured all of the evidence. Hughes turned back and is credited with saving his passengers from a tragedy. It occurred in the morning hours of January 9, 1965 in the Nicolum Valley (49.3068648, -121.2379782) in the Cascade Mountains near Hope, British Columbia, and killed four people. Click on a number on the map of Canada to learn more about that tsunami. Proc Geological Assoc of Canada 20:65–75, Mathews WH, McTaggart KC (1978) Hope rockslides, British Columbia. Given the volumes, the two largest landslides into Harrison Lake, which both had a runout distance of over a kilometre, are likely to have been tsunamigenic. The largest landslide in modern U.S. history (in terms of volume) was most likely one that occurred just last year in Bingham Canyon outside of Salt Lake City, Utah on April 10, 2013. Two small earthquakes were recorded in the area that day, but it’s still not clear what triggered the slide, which killed four motorists. They occur in all regions but are most damaging in the mountainous regions of British Columbia and Alberta and in the St.Lawrence Lowlands of Quebec and Ontario. [12] In a short distance, Stephanishin flagged down a Greyhound Lines bus traveling to Vancouver[13] and persuaded the driver, David Hughes, to return with him to Sumallo Lodge. Lipovsky, P. et al, (2008, July 17) The Jul2 2007 rock and ice avalanches at Mount Steele, St. Elias Mountains, Yukon, Canada. One of the largest fully submarine slope failures, the Storegga Slide, is on the continental shelf 120 km west of Norway (Haflidason et al., 2004). In: Landslides in research, theory and practice, Thomas Telford, London, pp 447–452 Google Scholar 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. large landslides in sensitive clay in eastern Canada. We found no simple precipitation threshold for triggering large landslides in sensitive glaciomarine clay in eastern Canada, suggesting that some complex temporal and spatial combi- The Progressive Conservative Party, led by Brian Mulroney, won the largest landslide majority government in Canadian history, while the Liberals suffered what at that time was the worst defeat for a governing party at the federal level. The dynamics of the Hope Slide.Bulletin of the International Association of Engineering Geology 16, 94– 98. The volume of rock involved in the landslide has been estimated at 47 million cubic metres. Analysis of the earthquakes associated with the 1965 Hope landslide and their effects on slope stability at the site. On April 23, 1966, a Royal Canadian Air Force Grumman CSR-110 Albatross (9302) serving with No. His two Facebook posts include a set of images of the landslide source and debris and several videos of the aftermath. “You can’t stop them. The incident also impacted several buildings. This study provides a really useful insight into the nature of previous rockslope failures into Lake Harrison. Over 150 people were evacuated and at least nine were injured, according to local reports. Type 2 craters can form for any of these styles of movement. The largest Canadian landslide known occurred in 1894 at Saint-Alban, Quebec. 1879. The geographic distribution of the fatal events is heavily concentrated in the provinces of British Columbia and Quebec even though Canada’s largest landslide disaster occurred at Frank, Alberta in 1903. Heart Mountain Landslide (Subaerial) The largest known subaerial landslide is the Heart Mountain Landslide in northwestern Wyoming. The landslide deposits are blocky and flow-like, suggesting that they were emplaced rapidly. Taku River: another very large landslide in British Columbia, Canada. For the Canadian band, see, Mathews WH, McTaggart KC (1969) The Hope Landslide, British Columbia. In the early morning hours of April 29, 1903, a freight train pulled out of the mine and was slowly making its way towards the townsite when the crew heard a deafening rumble behind them. 2020. About sharing. It would now be really interesting to see a model of the resultant tsunamis and also to date the landslide events. Six people are reportedly missing in Haines after a record-breaking rainstorm triggered destructive avalanches, landslides and flooding across Southeast Alaska. [17] The lower parts of the slide scar are underlain by felsite sheets (which may have failed first) while the upper parts of the slide scar are underlain by highly jointed Paleozoic greenstone beds.
