The 1949 earthquake was larger than the 1906 San Francisco earthquake, causing nearly a 500 kilometer-long segment of the Queen Charlotte Fault to break. The 1958 earthquake had a magnitude of 7.8 and led to a major landslide in Lituya Bay, Alaska. This resulted in a 1,720-foot (524-meter) tsunami that crashed into a mountainside, the largest ...

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 ...

The 1949 Queen Charlotte Islands earthquake was caused by a rupture on the Queen Charlotte Fault, which forms part of the boundary between the Pacific and North American plates. This fault runs from northern Vancouver Island, west of Haida Gwaii, up to the Gulf of Alaska. The earthquake ruptured the fault for a distance more than 500 km (311 mi ...
Volcanism of Canada. Mount Edziza, a stratovolcano in northwestern British Columbia. A topographic map of Canada, showing elevations shaded from green (lower) to brown (higher) Volcanic activity is a major part of the geology of Canada and is characterized by many types of volcanic landform, including lava flows, volcanic plateaus, lava domes ...
The only ‘important’ interior earthquakes, as classified by Natural Resources Canada, are the two strike-slip fault failures of local magnitude (M L) 6.6 and 6.9 observed in the Nahanni region of the Northwest Territories. Induced earthquakes, however, tend to occur in a 150-km-wide band east of the Canadian Rocky Mountains where the ...
Induced seismicity, typically minor earthquakes and tremors that are caused by human activity that alters the stresses and strains on the Earth's crust. [10] Interplate earthquake, an earthquake that occurs at the boundary between tectonic plates. [11] Intraplate earthquake, an earthquake that occurs within the interior of a tectonic plate. [12 ...
