I experienced my first magnitude 7.0-7.5 earthquake when I was 22 months old. It almost knocked me to the ground. That 1946 Vancouver Island earthquake struck Vancouver Island on June 23, 1946 at 10:15 a.m. with a magnitude estimated at 7.0 Ms and 7.5 Mw. The main shock epicenter occurred in the Forbidden Plateau area northwest of Courtenay. While most of the large earthquakes in the Vancouver area occur at tectonic plate boundaries, the 1946 Vancouver Island earthquake was a crustal event. Shaking was felt from Portland, Oregon, to Prince Rupert, British Columbia. There were a whole series of landslides in the Forbidden Plateau area that blocked streams and rivers to create lakes. The first hikers into the area gave them great names, Landslide Lake, Rock Fall Lake, Earthquake Lake etc.; over time these natural dams were eroded to nothing, leaving nothing but fading memories of those lakes. This earthquake is Canada's largest historic onshore earthquake. Canada has only been around for 155 years Three years later, an earthquake, an M8.1, struck at 8:01 p.m. PDT on August 2, 1949 in Haida Gwaii [formerly Queen Charlotte Islands], an interplate earthquake that occurred on the ocean bottom just off the west coast of the main south island. The shock had a surface wave magnitude of 8.1 and a maximum Mercalli Intensity of VIII (Severe).

Mount Meager Landslide

Further images and references, below 

On August 6, 2010 a massive lahar cascaded down from Capricorn Glacier at a speed of 30 m (98 ft) per second. Experts initially estimated that the volume of debris totaled 40,000,000 m3++ [cubic metres] = (1.4×109++ cu ft) which would make it the largest landslide on record in Canadian history.  The record was previously held by the 1965 Hope Slide that removed 47,000,000 m3 (1.7×109 cu ft) of rock from Johnson Peak. However the Meager landslide was later estimated to be more than 48,500,000 m3 (1.71×109 cu ft), making it the largest landslide in Canada's short 155 year history.  [Canada became a country on July 1, 1867].  The first seismograph (one of the first in the world) was built in Victoria in 1898, recording its first earthquake eight days later. This seismograph was operated by Francis Denison of the Meteorological Service of Canada, who recorded and described the M 7 earthquake on December 6, 1918 on the west coast of Vancouver Island.

The 2010 landslide at Mount Meager was 300 m (980 ft) wide and 2 km (1.2 mi) long, creating a dam across Meager Creek and the Lillooet River. This resulted in the creation of a lake just upstream. Early concerns that the dam might collapse and flood the Lillooet River valley ended a day later, when part of the dam ruptured and slowly released the accumulated water. An evacuation alert was rescinded, and nearly 1,500 residents were allowed to return to their homes on the weekend after the landslide occurred. No injuries were reported.

    The 2010 Mount Meager landslide was a large catastrophic debris avalanche that occurred in southwestern British Columbia, Canada, on August 6 at 3:27 a.m. PDT (UTC-7). More than 45,000,000 m (1.6×10 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.
