The last huge earthquake, the last really “Big One” to hit the Pacific Northwest Coast, struck around 9 p.m. on Jan. 26, 1700 — 321 years ago.
Called Cascadia, the magnitude 9.0 quake caused the entire Pacific Northwest coastline to suddenly drop 3 to 6 feet and sent a 33-foot high tsunami across the ocean to Japan.

“Japanese sources document this earthquake, which is the earliest documented historical event in Western Washington. Other evidence includes drowned groves of red cedars and Sitka spruces in the Pacific Northwest. Indian legends corroborate the cataclysmic occurrence,” according to HistoryLink.
The earthquake ruptured what is known as the Cascadia subduction zone from British Columbia to northern California — the area of overlap between two of the tectonic plates that make up the earth’s surface, the Juan de Fuca plate and the North American plate.

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

I know. I was being facetios.
In an earthquake-proof phone booth?
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.
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?”.
Speaking of Hawaii, if you really want something to worry about, search for “Hilina Slump”.
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
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).
