Most of the BC coast would be toast after these big ones...
What if....A Super disaster? Impact on Canada or the world? Napkin speculation

So I watched a show about Noah's Ark this morning. According to a historian there was an eruption so big it caused a tidal wave with a wave over 400 feet high. Really interesting stuff.

There's this 1958 tidal wave caused by a rockslide that makes that look calm...

Researchers are suggesting that if/when "the big one" hits the Pacific North-West it could quite possibly trigger another "big one" along the San Andreas Fault causing devastation all along the Pacific Coast from BC to California.
They were drilling off Oregon. What they found could shake all of California
Scientists have uncovered evidence that megaquakes in the Pacific Northwest might trigger California’s San Andreas Fault. A research ship’s navigational error revealed paired sediment layers showing both fault systems moved together in the past. This finding hints that the next “Big One” could...

The Most Doomed City in Canada
What the Big One will do to VictoriaVictorians live in one of the most doomed cities in Canada. It is a scientific certainty that the B.C. capital will be visited with a scale of civic destruction not seen in this country since the 1917 Halifax Explosion. Faced with a 50 per cent chance of a major quake happening within the next 80 years, it is more likely than not that many of the future victims of the Big One are already alive. Despite it all, Victoria often continues to act like a city that doesn’t stand on the brink of catastrophe.
The B.C. capital has the unique curse of being simultaneously threatened by several types of earthquakes at once. It is the closest Canadian population centre to the Cascadia Subduction Zone, the coming-together of two major tectonic plates that will eventually slip and yield “the Big One,” an earthquake expected to be a magnitude nine or greater. The city also sits directly atop a fault line, the Leech River fault, that can cause highly destructive shallow earthquakes. Victoria is also imperiled by “inslab” earthquakes—small slips from deep within the subduction zone that can radiate upwards.
Compounding the hazard is that Victoria is one of the oldest cities in Western Canada. The same brick buildings and historic homes that make the city a magnet for tourism are also the most vulnerable to the destructive power of an earthquake. Many of those buildings also stand atop soft soil expected to intensify the effects of any shaking.
A “Big One” level earthquake could be expected to kill up to 1,500 people in B.C., utterly dwarfing any disaster that has yet struck the province in modern times.
Earthquake damage map of Victoria in a worst case scenario. Anything coloured red is expected to suffer “complete” damage, meaning buildings will either collapse or require demolition after the fact.
