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.
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.
The 1700 Cascadia earthquake occurred along the Cascadia subduction zone on January 26, 1700, with an estimated moment magnitude of 8.7–9.2. The megathrust earthquake involved the Juan de Fuca Plate from mid- Vancouver Island, south along the Pacific Northwest coast as far as northern California. The plate slipped an average of 20 meters (66 ...
The 2010 Central Canada earthquake occurred with a moment magnitude of 5.0 in Central Canada on 23 June at about 13:41:41 EDT and lasted about 30 seconds. [3] [4] The epicentre was situated approximately 56 kilometres (35 mi) north of Ottawa, Ontario, [5] in the municipality of Val-des-Bois, Quebec. [6] Canada's capital, Ottawa, declared this ...

On November 30, 2018, at 8:29 a.m. AKST (17:29 UTC), a magnitude 7.1 earthquake hit Anchorage in South Central Alaska. The earthquake's epicenter was near Point Mackenzie, about 10 miles (16 km) north of Anchorage, and occurred at a depth of 29 miles (47 km). It was followed six minutes later by a magnitude 5.7 aftershock centered 2.5 miles (4. ...
A pie chart comparing the seismic moment release of the three largest earthquakes for the hundred-year period from 1906 to 2005 with that for all earthquakes of magnitudes <6, 6 to 7, 7 to 8, and >8 for the same period. The 2011 Japan quake would be roughly similar to Sumatra. Earthquakes of magnitude 8.0 and greater from 1900 to 2018.
A magnitude 4.2 earthquake was felt widely across the nation's second largest city Friday and shook things off shelves near the epicenter in a small mountain community east of Los Angeles, but ...
