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 neighboring 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., to the south. It is arguably the most unstable mountain massif in Canada and may also be its most active landslide area. 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. These events were attributed to structurally weak volcanic rocks, glacial unloading, recent explosive volcanism and glacial activity. Those who dance with earthquakes and volcanoes are considered mad by those who cannot smell the sulfur.

Monster Quake/Tsunami Are We Next? - From British Columbia's Knowledge Network


We are overdue.  You Can Watch This Knowledge Network Video Online Until: May 29.  The longer it takes to develop, the bigger it will be.

Seismologists say there is a 37 percent chance a gigantic magnitude 8.0 or 9.0 Megaquake along the 1,000km long Cascadia Fault, here, on the West Coast of Canada and North West United States, in the next 50 years.


45:53 Minutes


This Megaquake and subsequent Tsunamis will hit Vancouver Island, Vancouver and Victoria in British Columbia, Canada and would continue up or down through Seattle and Portland and all of the United States Pacific North-west Coast and Northern California.
It's hard to imagine the power of these earthquakes and tsunamis. When the first megaquake in over 300 years hits the ground beneath our feet, in 5 minutes of mighty shaking we will have been thrust 20 meters (66 feet) or so to the West towards the Pacific Ocean. And, there will be aftershocks. So, let's break it down with sand. The evidence suggests that the last Cascadia megaquake here took place at about 21:00 on January 26, 1700. Since then the Cascadia Fault has been locked and building up pressure. There is evidence that this is a recurring event, about every 300 years or so, over the last 10,000 years and more. Research is ongoing, but most almost everything suggests that something very, very ugly is about to happen.


During Emergency Week last year I was advised that a Cascadia Megaquake was the most serious senerio for us. Since, I have written a Blog/Webpage entitled Cascadia Megaquake which you can find here.


An earthquake (also known as a quake, tremor or temblor) is the result of a sudden release of energy in the Earth's crust that creates seismic waves. The seismicity, seismism or seismic activity of an area refers to the frequency, type and size of earthquakes experienced over a period of time.
Since 2004, a series of rare super-earthquakes has been sweeping the Pacific Rim; among them, the earthquake that triggered the Japanese tsunami - 15 times bigger than scientists had thought possible. North America is the only continent that has not yet been hit. Why are we ostricfied? (One who tries to avoid disagreeable situations by refusing to face them).
May 22, 1960 1960 Valdivia earthquake 9.5
Are we next? If so, are we ready? Startling clues show a giant quake off our west coast is imminent, and could be much worse than anyone has previously predicted.


Latest Earthquakes from the United States Geological Survey.


The Geological Survey of Canada (GSC) provides information and an archive on Earthquakes Canada, including some of the most recent:


There was even a small cluster in Alberta:

Historical earthquakes

earthquakes (before 1901). For Earthquakes in the twentieth century, see List of 20th century earthquakes. For Earthquakes after 2000, see List of 21st century.
In Canada currently there is an automatic notification of significant earthquakes to agencies who need to respond rapidly. Currently dam operators in Ontario, New Brunswick and Quebec use this service (“ANHAS”) to prioritize and set the level of dam inspection. You can learn more about it on this .pdf file.
