I am the Man From Minto© ™ ® - A Prospector Who Knows His Rocks And Stuff© ™ ® The 2010 Mount Meager landslide was a large catastrophic debris avalanche that flowed to the south, into the Lillooet Valley British Columbia, Canada, on August 6 at 3:27 a.m. PDT (UTC-7). More than 45,000,000 m3 (1.6×109 cu ft) of debris slid down Mount Meager, temporarily blocking Meager Creek and destroying local bridges, roads and equipment. It was one of the largest landslides in Canadian history and one of over 20 landslides to have occurred from the Mount Meager massif in the last 10,000 years. Although voluminous, there were no fatalities caused by the event due in part to its remote and uninhabited location. The landslide was large enough to send seismic waves more than 2,000 km (1,200 mi) away into the neighbouring U.S. states of Alaska and Washington and beyond. Multiple factors led to the slide: Mount Meager's weak slopes have left it in a constant state of instability. The massif has been a source of large volcanic debris flows for the last 8,000 years, many of which have reached several tens of kilometres downstream in the Lillooet River valley.[6], to the south. It is arguably the most unstable mountain massif in Canada and may also be its most active landslide area.[6][1] And on the north side lies Downton Lake Hydro Reservoir, impounded by the La Joi Dam, the uppermost of the Bridge River Project dams. The earliest identified Holocene landslide was in 7900 BP (before the present, or read it as the number of years ago). Further landslides occurred in 6250 BP, 5250 BP, 4400 BP, 2600 BP, 2400 BP, 2240. BP BP, 2170 BP, 1920 BP, 1860 BP, 870 BP, 800 BP, 630 BP, 370 BP, 210 BP, 150 BP and in 1931, 1947, 1972, 1975, 1984, 1986 and 1998.[6] These events were attributed to structurally weak volcanic rocks, glacial unloading, recent explosive volcanism and Little Ice Age glacial activity.[1] Those who dance with earthquakes and volcanoes are considered mad by those who cannot smell the sulfur.

187 views • Aug 25, 2020 • Shake Up Expert Interview: Kwiaahwah Jones, Haida Artist This video series features experts discussing earthquake science and technology and Indigenous knowledge and oral history about earthquakes, represented in MOA’s Northwest Coast collection, as part of the MOA exhibition Shake Up: Preserving What We Value. In conjunction with major seismic upgrades to the Museum, MOA’s exhibition, Shake Up: Preserving What We Value, explores the convergence of earthquake science and technology with the rich Indigenous knowledge and oral history of the living cultures represented in MOA’s Northwest Coast collection. Beyond scientific discoveries, Shake Up also puts into the foreground traditional knowledge of earthquakes and natural disasters that has been passed down through generations throughout many cultures.
