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.

the tsunami is almost certainly not going to reach i95. the shaking is the bigger issue for most of WA and OR.

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.

What’s the bad news for chicago?

The last several years, every time I consider the idea of someday moving back to Portland, I always think of this "The Big One" article. (With my mixed luck, the PNW mega-shark-quake-nami is just waiting for me to move back, so that'd really be irresponsible of me.)

Are there not natural disaster risks everywhere? Floods, fires, tornadoes, hurricanes...

> But a lot of the coastline is tall enough that you can usually find a safe place nearby if a tsunami warning sounds. I recall driving US-101 in Oregon some years back and kept seeing "Tsunami evacuation route" signs. https://www.oregon.gov/oem/Documents/Tsunami_Evacuation_Sign...

We have those all along the Pacific coast.

Yep. I only recall seeing them in Oregon though - not California or Washington (Washington has warning signs for everything else though - including no warning signs - https://i.imgur.com/T868pkg.jpg )

Floods, fires, tornadoes, and hurricanes only produce grave threats to the individual towns, cities, and maybe some multi-county regions that they cross. For individual incidents, we're relatively prepared beforehand and we know how to respond afterward.

There's no comparison to having nearly everything in multiple states obliterated to the point that rescue takes weeks or months to arrive. We're not equipped to instantly support millions of refugees in the US. Moving hundreds of thousands of people for Katrina was probably at the upper limit of what we can effectively do (for various definitions of "effectively"). A killer quake out west could have 10 million refugees.

Washington has them, it was one of the first things I noticed when I got the motorcycle out for a coastal ride when I first moved here 20-some years ago. Couldn't tell you exactly where, but they're there and within an easy Saturday ride from Redmond. (Westport or Grayland, maybe?)

Except for an occasional mild snowstorm, Antarctica looks pretty safe (as long as you're upwind from Mt. Erebus.)

The northeast is pretty damn 'safe', as long as you can handle the occassional downed tree and subsequent power outage.
