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 dataset compiles information and photographs collected at 49 observation stations during a field campaign conducted from July 31 to August 11, 2025, in the central part of the Kivalliq region. It includes the locations of sites where ice-flow indicators were measured, along with their relative chronology where it could be determined in the field. It also includes the locations of till sampling sites collected for geochemical and indicator mineral analyses, as well as sites where boulders and bedrock surfaces were sampled for terrestrial cosmogenic isotope dating. Analytical results and interpretations will be presented in subsequent publications.

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.

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.

Magnitude 5.7 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.

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.

Prospectivity model highlights areas of Canada with the greatest potential for magmatic nickel deposits. The preferred prospectivity model is based on public geological, geochemical, and geophysical datasets that were spatially indexed using the H3 discrete global grid system. Each H3 cell is associated with a prospectivity value, or class probability, calculated from the best-performing gradient boosting machines model. Model results are filtered to include the top 20% of prospectivity values for visualization purposes.

In 1997, a magnitude 4.6 earthquake occurred 3 to 4 km beneath the Strait of Georgia, near Vancouver. This scenario visualizes the effects of that event if it occurred today with a magnitude of 5.0. A magnitude 7.0 Georgia Strait scenario is also provided, and represents a less likely but more consequential case for comparison.

Prospectivity model highlights areas of Canada with the greatest potential for Mississippi Valley-type zinc deposits. The preferred prospectivity model is based on public geological, geochemical, and geophysical datasets that were spatially indexed using the H3 discrete global grid system. Each H3 cell is associated with a prospectivity value, or class probability, calculated from the best-performing gradient boosting machines model. Model results are filtered to include the top 20% of prospectivity values for visualization purposes.

The National Earthquake Scenario Catalogue, presents the probable shaking, damage, loss and consequences from hypothetical earthquakes that could impact Canadians. 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.
