Which fault lines closest to Canada's west coast?

The fault lines closest to Canada's west coast include the Cascadia Subduction Zone, where the Juan de Fuca Plate is subducting beneath the North American Plate. This zone is capable of producing large earthquakes, including the potential for a megathrust earthquake. Other notable faults in the region include the San Andreas Fault system to the south and various strike-slip faults in British Columbia, such as the Queen Charlotte Fault. These geological features pose significant seismic risks to coastal communities.
