Ha… it’s not like the earthquake will stop at I-5 like it’s a magic shield. If the quake knocks out utilities and services everywhere west of the cascades, this I-5 ‘line’ is meaningless.

I believe they are referring to the tsunami that follows the earthquake, based on evidence from before the Europeans colonized the continent.

They are not—simply the shaking. The tsunami will only be a few feet tall at most in that part of Puget Sound.

Don't get too comfortable if you're on the East Coast. Whatever survives sea level rise due to global heating, will be wiped out by the megatsunami caused by the ensuing landslide when La Palma erupts.

My East Coast tsunami money is on a submarine landslide. Long odds but what a payout.

In theory tho, a well placed earthquake could bump those odds https://geology.com/noaa/atlantic-ocean-tsunami/

At least in Oregon, I-5 is 50 miles away from the coast and separated from it by a small mountain range. I don't think we're too worried about tsunamis getting all the way to I-5. Definitely will get to Highway 101 in some spots, however. But a lot of the coastline is tall enough that you can usually find a safe place nearby if a tsunami warning sounds.

What is Microsoft's contingency plan for this? Or, in fact, the FAANG's and other west-coast tech companies? The effects of a Cascadia earthquake on the US and world economy would be "interesting".

I suppose it depends on data centre locations. Data centre on the west coast? I'd be wary, mostly central and east coast? Less of a worry.

All the clouds will go down at the same time. The control planes for all them are heavily managed in Seattle.

From a cloud perspective, I'd hope everything just carries on.

But from a 'shareholder' perspective I expect the stock markets will go silly at the first sign of shaking.

separately, there’s risk from lahars from mt. Baker and mt. Rainier. Catastrophic Baker lahars could potentially bury even Renton based on some estimates.
