Where is the fault line in BC?
The Cascadia Subduction Zone (CSZ) is a 1000 km fault that runs from Northern Vancouver Island to Northern California. The fault itself is a boundary between two tectonic plates: the Juan de Fuca tectonic plate is moving towards and getting shoved under the North American plate.
Is British Columbia on a fault line?
The area of greatest risk in B.C. is along the Cascadia subduction zone, a fault running from northern Vancouver Island to northern California that separates the North American tectonic plate and the Juan de Fuca plate west of Vancouver Island.

Michael Bostock says the Okanagan Valley lies on an ancient fault line which has not been tectonically active since the Oligocene period — 23 million years ago — although it still represents a zone of weakness as a fault zone.
Where in Canada are earthquakes most likely to occur?
The Pacific Coast is the most earthquake-prone region of Canada. In the offshore region to the west of Vancouver Island, more than 100 earthquakes of magnitude 5 or greater (large enough to cause damage had they been closer to land) have occurred during the past 70 years.

“The valley is split down the middle by a big fault, which has resulted in very different rock types on either side of the valley,” says Redding.

How big was the earthquake on Vancouver Island?
This earthquake, larger than the 1906 San Francisco earthquake, caused nearly a 500-km-long segment of the Queen Charlotte fault to break.

What kind of geology is found in British Columbia?
Geology faults are part of the British Columbia Digital Geology, which is the data source used for the seamless province-wide, up-to-date, and detailed bedrock geology. The bedrock geology integrates all details of compilations from 1:50,000 to 1:250,000.
