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 )

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?)

It's been a few years, but I don't recall them in Kalaloch, La Push, or Ozette... but then that was '09. The picture of the no warning signs warning was on the road to Ozette. It does appear that they are there now, so it might have been me misremembering ( https://goo.gl/maps/ofY3GGHDnuG5GWaZ6 )

> Kenneth Murphy, who directs FEMA’s Region X, the division responsible for Oregon, Washington, Idaho, and Alaska, says, “Our operating assumption is that everything west of Interstate 5 will be toast.” I remember when this article came out, my mom called me and said "you'll be okay, you're east of I-5, right?" "Yeah mom." About 6 blocks east. Plenty of cushion.

This made me laugh as I'm about 2 blocks West of Hwy 5 in wa

They've changed them, though. They used to have a person climbing a hill as the wave comes chasing after them. Can't find a good example on image search. I found the old signs to be morbidly amusing. Like my spindly little legs are going to save me.

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

AWS has lots of engineers in Seattle, but control plane is distributed. I'd personally expect a long delay in getting any fixes to things, but that many sites would be just fine.

I think you overestimate how resilient any of the cloud providers are to a massive gray failure. Lots of west coast infrastructure will flap. The survivors will have other priorities. I am going to revise my statement, I predict! a partial or nearly complete failure of the internet across multiple continents when this earthquake goes off.

I stumbled across one of Nick's Volcano lectures on Youtube about a year ago and was unexpectedly captivated to watch the entire thing, which lasted about an hour! As someone who has always held an interest in Geology and Deep History, I really appreciate his efforts to make his University content available to the public.

Yes, I should have said more about the channel. If only we could all have teachers who are so enthusiastic and makes topics very interesting and easy to follow! All of his content is very good and captivating. If anyone is interested in pacific northwest geology, I'd highly recommend watching more of his stuff. He also has his own personal channel separate from CWU here and still making new content: https://www.youtu…

Nick Z is the king of making it fun and informative to learn about geology. He has dozens of great videos.

Nick Zentner of Central Washington University did a really good talk about this article and some of it seems overblown, specifically the "west of I5 will be toast." They've placed GPS sensors throuout the PNW and one of the more interesting things is that Oregon and Washingtons land is working in a spiral, and the land is moving in a circular pattern. Also that the hot spot that creates Yellowstone used to be off the…

>The hotspot stays in the same spot, but the earths crust moves over it changing it's position over time.

I'm guessing this is why the Hawaiian islands look the way they do: a hotspot was underneath and formed volcanoes over time, which turned into the islands we now have, as the crust moved northwest.

For some reason I had the impression that us-east-1 was kind of the flagship for AWS, although actually typing that out seems quite silly.

It is the flagship.

To me the big takeaway from the article was that it would take two years to restore electric power in much of the region.

The tsunami will be much more limited, and over quickly. Rebuilding so much cannot happen very fast.

It’s actually closer to every 500 years at the latitude Seattle and Portland are at. The 300 year figure only applies to the southern Oregon and Northern California portion of the fault, and is based on turbidities and controversial. Still, this is an under-appreciated risk of living in the northwest. There’s plenty of societies living in subduction zones across the planet. But few with as little awareness of their f…

I transplanted to the PNW back in the 1990s, knowing well about the quakes. Previously I lived up & down the U.S. east coast and also NE Ohio. That latter gets small quakes, too, but mostly we thought it was an heavy vehicle driving by..

Yeah this is what reminded me. Figured I'd revive the "mega earthquake" while the news was buzzing about the "mega flood".

Might as well make it a trifecta: https://www.scientificamerican.com/article/western-megadroug...
