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rescinded, and nearly 1,500 residents were allowed to return to their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.
