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 5.6 rupture scenario near Ottawa along the Gloucester Fault in the south of the city. This fault is not known to be active, but this scenario is representative of seismicity in the Ottawa Valley.

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.

In September 1732 a damaging earthquake occurred immediately beneath the Island of Montréal. This scenario visualizes the effects of that event if it occurred today with a magnitude of 5.0, and represents a strong ground shaking event that could strike Montréal.

A magnitude 5 earthquake scenario along an unnamed fault located about 15 km north-northeast of Burnaby City Hall and directly south of Mt Elsay. This fault is not known to be active, but this scenario represents a small but damaging event in the North Shore Mountains.

Ottawa planning scenario using the 2010 Val-de-bois, QC earthquake hypocentre and fault plane geometry from Ma & Motazedian, 2012 and Atkinson & Assatourians, 2010. This scenario uses a larger magnitude event than those that have been observed to date for that location, within bounds of the national seismic hazard model. Maximum magnitude of 7.95 is obtained from CanSHM6 for GATINEAU region.

Magnitude 5.2 earthquake scenario along the Vedder Fault which runs northeast along Vedder Mountain. This earthquake is located about 18 km east of Abbotsford City Hall. This fault is not known to be active, but this scenario represents a small but damaging event near Abbotsford town centre.

In 1949 a magnitude 8.1 earthquake occurred on the Queen Charlotte Fault, off the west coast of the Haida Gwaii archipelago. This magnitude 8.0 scenario along the Queen Charlotte Fault is slightly different and closer to population centres than the magnitude 7.8 earthquake that occurred in 2012.

Faults in the valleys near Ottawa could rupture and produce strong, shallow earthquakes. This magnitude 5.5 scenario visualizes the effects of such an event. It does not represent the most severe earthquake that could occur, but one that is more likely and could still cause damage.

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.
