West Coast. M w 8.7 – 9.2 megathrust earthquake along the Cascadia subduction zone. 1700. Eruption of Tseax Cone. Volcanic eruption. Tseax Cone, British Columbia. West Coast. 2000. One of Canada's worst known geophysical disasters.
Six large earthquakes have occurred along the Queen Charlotte Fault within the last hundred years: a magnitude 7 event in 1929, a magnitude 8.1 in 1949 (Canada's largest recorded earthquake since the 1700 Cascadia earthquake), a magnitude 7.8 in 1958, a magnitude 7.4 in 1970, a magnitude 7.8 in 2012, and a magnitude 7.6 in 2013.

The Cascadia subduction zone is a 960 km (600 mi) fault at a convergent plate boundary, about 100–200 km (70–100 mi) off the Pacific coast, that stretches from northern Vancouver Island in Canada to Northern California in the United States. It is capable of producing 9.0+ magnitude earthquakes and tsunamis that could reach 30 m (98 ft).
Significant earthquakes associated with this seismic zone include the 1732 Montreal earthquake, the 1935 Timiskaming earthquake, the 1944 Cornwall–Massena earthquake, and the 2010 Central Canada earthquake. Between the years 1980 and 2000 there were 16 earthquakes stronger than a Richter 4.0, with many more of a lesser magnitude. The zone ...
2 [1] The 1946 Vancouver Island earthquake struck Vancouver Island on the coast of British Columbia, Canada, on June 23 at 10:15 a.m. [1] with a magnitude estimated at 7.0 Ms[2] and 7.5 Mw. [6] The main shock epicenter occurred in the Forbidden Plateau area northwest of Courtenay. While most of the large earthquakes in the Vancouver area occur ...
The 2000 Kipawa earthquake (or 2000 Kipawa "Millennium" earthquake [1]) struck Quebec and Ontario, Canada with a moment magnitude of 5.2 at 6:22 a.m. on January 1. [2] It occurred in the Western Quebec Seismic Zone. The main shock epicenter was located in Lake Kipawa about 10 km (6 mi) north of Témiscaming in southwestern Quebec and 70 km (43 ...
In most cases, aftershocks are smaller and fade over time, but there is a 1 in 20 chance that, in the next week, there will be another earthquake of magnitude 4.7 or larger.
