This is a magnitude 5.0 earthquake scenario along the Burlington Toronto Structural Zone — a fault near Toronto and its surrounding region. This fault is not known to be active but demonstrates a plausible earthquake scenario for the Toronto region.

Full rupture of the Cascadia interface fault, the fault defining the boundary between the North American and Pacific Ocean plates. This magnitude 9.0 event, often referred to as ‘The Big One’, affects most communities in southwestern British Columbia.

In 1949 a magnitude 8.1 earthquake occurred on the Queen Charlotte Fault, off the west coast of the Haida Gwaii archipelago. This magnitude 7.7 scenario along the Queen Charlotte Fault is slightly different and closer to population centres than the magnitude 7.8 earthquake that occurred in 2012.

The Probabilistic Seismic Risk Model for Canada introduces a structured framework of indicators that profile the physical, social and economic dimensions of earthquake risk at the neighborhood scale. Risk metrics include measures of building damage and collapse probability, life safety and expected economic losses. An overall risk rating is also provided which aggregates the physical, social, and economic dimensions of risk. The probabilistic assessment reports information based on both the ‘total’ impact as well as the ‘percentage’ impact. It considers only damage to buildings, and their inhabitants, from earthquake shaking, and therefore does not include damage to critical infrastructure or vehicles. Losses from secondary hazards, such as aftershocks, liquefaction, landslides, or fire following are also not currently included. The information is provided at the approximate scale of Census dissemination areas, and is intended to support planning and emergency management activities in earthquake prone regions. This project is run by the Geological Survey of Canada's Public Safety Geoscience Program. For inquiries related to Canada's Seismic Risk Model, please contact Tiegan E.

The Beaufort fault in Eastern Vancouver Island is probably an active fault, near Courtenay/Comox/Cumberland. Based on current science, this fault may have ruptured in the 1946 magnitude 7.3 Vancouver Island Earthquake. This scenario represents a smaller magnitude 5.2 event.

A magnitude 5.9 earthquake near Montreal, along the Milles-Îles Fault. This fault is not known to be active, but this scenario represents a small but damaging event near the City of Montreal.

Full rupture of the Leech River Fault, a fault that cuts southern Vancouver Island and extends beneath Greater Victoria. Based on current science, this magnitude 7.3 earthquake scenario represents the strongest ground shaking event that could strike the region, and is one of Greater Victoria’s most severe events.

This is a magnitude 5.0 earthquake scenario under Lake Ontario, very close to Toronto. This fault is not known to be active but demonstrates a plausible earthquake scenario for Toronto region.

In 2015, a magnitude 4.7 earthquake occurred 60 km beneath Sidney, BC. This scenario visualizes the effects of that event if it had a magnitude of 7.1.

Magnitude 5.5 earthquake scenario located directly southeast of Ladysmith Town Centre. This fault is not known to be active, but this scenario represents a small but damaging event near Ladysmith and Burleith Arm.
