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.

The LIVE Look and Feel of a M9.2 to M9.3 Megaquake and Megatsunami - The Great Alaskan Earthquake 1964 - Magnitude 9.2 - Tsunami Affects

Update lead in to 1964 Alaskan Earthquake

 Grandparents: No one will come to your aid if this happens.  As a 

 retired disaster coordinator, my first decision would be to go to the 

 schools and try to save as many children as possible.
This is NOT a 'worst case' scenario; it has happened right here 

 over forty-one (41) times in the last 10,000 years, on average, every 

 249 years. Reference: 1964 Alaska earthquake – Wikipedia

You have a choice: You can continue spending all of your money, 

skills, talent and wisdom running around and having a good time 


can join us in helping everybody get ready.

That is going to take a lot of knowledge, money and time.

And, I need your help, firstly in researching, learning, 

photographing / video and writing, in a coordinated way, all we 

can about these gigantic earthquakes, and secondly, how we are 

going to save our families, and indeed, as many lives as possible, 

including your own.

Your comments and suggestions would be appreciated at:

Please watch this video clip all the way through. It will take 

about the same length of time that the shaking was 

experienced in the 1964 Alaskan earthquake. This M9.2 

megathrust earthquake lasting four minutes and thirty 

eight seconds. This magnitude 9.2 megathrust earthquake is also 

known as the Great Alaskan earthquake and Good Friday 

earthquake. MAGNITUDE SCALE AS A M9.3
