Stress is building up 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 Vancouver Island in the Ring of Fire?
But Vancouver is in volcano-country. The Cascade Range (also known as the Cascade Mountains) which makes up part of the Pacific Ring of Fire, is a 1,300 km chain of volcanoes extending from California to southern British Columbia that has been erupting in intervals for around the last 29 millions years.
Will Vancouver Island go underwater?
No. Vancouver Island is part of the North American plate. The fact that there is water between Vancouver Island and the mainland is function of the current position of sea level. However, the west coast of Vancouver Island will drop as much as a metre or two when the next megathrust earthquake occurs.
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.
What would happen if an earthquake hit Vancouver Island?
In a big earthquake the seafloor offshore from Vancouver Island will be uplifted and the area along the coast will sink, but at worst that sinking will only be a few meters.

Is Vancouver going to sink?

Is Vancouver protected from tsunami?
Tsunamis can happen in Vancouver if underwater landslides cause earthquakes in the Fraser River delta or if any are present within the Strait of Georgia.However, for the most part, Vancouver is protected by the Olympic Peninsula and Vancouver Island.
