In 1700, the ‘really big one’ — a magnitude 9.0 earthquake — hit Western Washington

An Oregonian article said everything west of I5 would be destroyed or rendered unusable. There is a bill in the Oregon legislature to research where to put the survivors after it hits.

I lived on Guam in 2015 when the 7.1 one struck there. Fun stuff. Our house settled about 8 Inches and we had to have the exterior replumbed because it messed up the slope on the sewer lines

[moehoward]

Yes. Also was in Burbank hills for the Northridge and was set to move north to Lafayette a few days after the Loma Prieta. After those two in Ca, the few here in Wa state were like kiddie rides.

And, how many present politicians were, still, in political office, at the time?

You should have heard what they said about his mama.

Anyone else in the Seattle area in 2001 for the: https://en.wikipedia.org/wiki/2001_Nisqually_earthquake It was only 6.8 but it brought thew city to it’s knees for days.

Yup. Was at my work office in Everett. Was outside seconds after and got to see the barely perceptible rolling motion of the land from me to a few hundred yards off. looked just like an small ocean swell of waves. so amazing. The Earth Is Alive!

In other words, there is no safe space - you’re all going to die.

Man plans. God says, “Really?”

I know. I was being facetios.

In an earthquake-proof phone booth?

[HKMk23]

When the shaking stopped, the Indian chief looked at his medicine man and asked, “What was that?”

The wise, old medicine man look back at the chief and said, “Great Chief, that was Juan.”

The Chief sat awhile in silence, then said, “You tell great spirit, one is enough; we no want two.”

Anyone interested in this should read Cascadia’s Fault.

They can tell a lot from the displacement.

Subduction zone earthquakes can be monsters. The 1960 9.4-6 earthquake was also result of a subduction zone.

Interesting observation in that article: Seismologists know that how long an earthquake lasts is a decent proxy for its magnitude. The 1989 earthquake in Loma Prieta, California, which killed sixty-three people and caused six billion dollars’ worth of damage, lasted about fifteen seconds and had a magnitude of 6.9. A thirty-second earthquake generally has a magnitude in the mid-sevens. A minute-long quake is in the high sevens, a two-minute quake has entered the eights, and a three-minute quake is in the high eights. By four minutes, an earthquake has hit magnitude 9.0.

There is also a bill in the Oregon legislature to confiscate private property in a declared emergency.

Another issue I’ve never seen mentioned in these discussions is “How much of Hawaii is the tsunami from this earthquake going to destroy?”.

[PTBAA]

Speaking of Hawaii, if you really want something to worry about, search for “Hilina Slump”.

[DuncanWaring]

Also amusing, in June of 2019 Oregon repealed a 1995 prohibition on constructing new public facilities within the tsunami-inundation zone.

Municipalities are free to build schools, hospitals, prisons, other high-occupancy buildings, firehouses, and police stations in areas that will be destroyed when the tsunami strikes.

On that thought....now that the obamas live there.....give me a few minutes to contemplate the outcome

[CommerceComet]

LOL. Right. The earthquake will be over in a minute, maybe two or three tops. In an M9, you can’t stand up or walk. You aren’t going to get very far away from cliffs in that short time with the ground violently shaking.

Crawl like hell, I guess. If this struck in the winter, I'm guessing you'll see avalanches in the Cascades in areas where avalanches are not that common. That would be a big perturbance to any snow field on a slope and might break loose snow that would normally just stay put. Once something breaks loose, a cascading effect is unleashed (no pun intended).
