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.

Episode 1 - Ripples in a Pond

Johanna sets up two different, equally likely scenarios. First, The Big One: a 9.1 mega-thrust earthquake. Then, the lesser known 7.0 magnitude crustal quake which is shallow and strikes beneath the city of Vancouver. The outcome is catastrophic.

Episode 2 - The First 24 hours

The West Coast is cut off from the rest of BC and Canada. A major tsunami has hit the West Coast of Vancouver Island. Those who survive gather and try to locate loved ones. Emergency workers race to rescue those who are trapped and assess the damage.

Episode 3 - 72 Hours - When Supplies Run Out

Three days after the quake, food and supplies are starting to run out. Communication lines improve. Social media and radio are a lifeline. Families reunite, but people are afraid to go into their homes.
Episode 4 - One Week and a New Normal

We are still in the life-saving phase but rescue becomes recovery. Outside aid arrives and we realize the scope of the damage. Thousands are homeless but communities gather together to create some sort of normalcy.
Episode 5 - A Month, A Year, and Lessons from Christchurch

Survival and resilience are key to the rebuilding efforts. Hear how to have the plan you need so you can do it. Two survivors of Christchurch quakes share their essential tips. Preparation is empowerment. We are all in this together.
