To the north of California's famous San Andreas fault is a less known, but possibly more deadly, fault line. The Cascadia subduction zone runs some 700 miles from northern California to Vancouver.
In a deeply reported article for The New Yorker, Kathryn Schulz tells the tale of how this fault lies dormant for periods of 243 years, on average, before unleashing monstrous tremors. The Pacific Northwest is 72 years overdue for the next quake, which is expected to be between 8.0 and 9.2 in magnitude.

Well the, that would point to being, on average, overdue.
Now I am going to be the devil’s advocate here: 13 “recent “ earthquakes is not significant over the life of the continent.
It is akin to predicting global temperatures using just the past 13 years.
If the study went back millions of years, there would be hundreds or thousands of observations.
I hope you understand my point. I am not trying to be obtuse.
I don’t think we ever expected the 82d airborne to evacuate and patrol New Orleans, either
But the precedent was established
Or again , you must expect jade helm is about obama planning for the contingency of a large scale insertion of spec ops into a middle eastern country or other foreign country ....
Won't happen. The only times DC floods is water coming downstream on the Potomac and occasionally with the right winds coming up from the bay. Most of the time the 180 degree turn in the lower Potomac blocks the surges. That bend in the river would definitely absorb any energy left from a tsunami.
The flood to end all floods (ha) was in ‘98.
I was there in ‘79 too, attending UND. I guess you and I must have been students there at the same time?
My brother and his family lived along the English Coulee and their house was badly damaged.
I helped sandbag in ‘79 and I remember a Saturday morning when things were under control and for some reason I was strolling across the empty campus, just kind of trying to unkink a little.
I happened to walk past the law school and suddenly recalled that I had been scheduled to take the LSAT exam that weekend. What the hell, I thought, I’ll catch it next time.
Never did, to the eternal gratitude of the legal profession and myself as well.
That video is interesting. I was a Ph.D. student in Seattle when the SF World Series earthquake hit. The highway that collapsed there was of the same design as the Alaskan Way Viaduct. Always made me nervous when I drove over the viaduct. Wouldn’t want to be under it or on either level when the big one hit.
Apparently, the tsunami danger depends on the epicenter of the quake. The simulated quake in the video didn’t trigger one but I have seen some projections about tsunamis when the epicenter is just off the coast near the mouth of the Strait of Juan de Fuca. With little warning, tsunamis could race up the Strait and down the Puget Sound causing horrific damage to the cities along the shores including Vancouver, BC, and Seattle/Tacoma area. Apparently, the geologic record in the area shows a history of massive tsunamis.
Why yes, Jade Helm is the answer to everything! UFO’s will have to wait their turn.
The Tsunami we are talkin about would simply roll over that turn.
Don’t bring me down....we are dreaming here, remember.
We are all Dreamers now.
I’m well aware of Ezekiel 38-39...
Isaiah 17:1
Psalm 83
I'm not an engineer but it seems to me that the floating bridges across Lake Washington would be more likely to survive a quake than a traditional span bridge. If those bridges survived, Ship Canal Bridge could be by-passed using them and I-405 on the east side of Lake Washington. Very inefficient but possible.
The best way to think of Seattle is not as an island but as two peninsulas whose tips almost touch, only the separated by the ship canal. Access from the west is hindered by the Puget Sound and from the east by Lake Washington.
That’s funny, where is my check?
Thanks BenLurkin. Apropos of nothing, there's some flakery on YT and elsewhere that the end of the world is coming in September.

FERMA didn’t arrange it, but there was one in DC. Caused millions of damage to National Cathedral and to the Washington Monument which was closed over a year for repairs. Also friends told me they had chimney damage and other minor repairs to stone and brickwork. Some had doors that stuck or unstuck. Off to see San Andreas, will report back.
Having watched live on camera what the tsunami did in Japan, traveling over the coastline and then up the rivers for 70 miles or more, I would not be too sanguine about Washington DC being immune from a big one that crosses the Atlantic, as from La Palma
a 5oo footer would go over the eastern shore and up the Chesapeake Bay, then up the Potomac
What’s the highest elevation between the Atlantic coast and DC?
If I was running away from a wave I wouldn’t stop in Washington DC!
For disaster afficianados!

One commentor noted when this was released in the USA the part about the Yellowstone supervolcano was cut
Charlie Frost: You'd have to keep a thing like this underwraps. I mean, just think about it, okay? First, the stock market would go. Then the economy, boom! The dollar, boom! And then pandemonium in the streets. War, genocide, ba-ba-ba-ba, boom, boom, boom!
Jackson Curtis: Bullshit. Nobody could keep that big a secret, Charlie. Somebody would blow the whistle.
“Thanks to that work, we now know that the Pacific Northwest has experienced forty-one subduction-zone earthquakes in the past ten thousand years. If you divide ten thousand by forty-one, you get two hundred and forty-three, which is Cascadias recurrence interval: the average amount of time that elapses between earthquakes.”
“Counting from the earthquake of 1700, we are now three hundred and fifteen years into a two-hundred-and-forty-three-year cycle.
It is possible to quibble with that number. Recurrence intervals are averages, and averages are tricky: ten is the average of nine and eleven, but also of eighteen and two. It is not possible, however, to dispute the scale of the problem.”
I’m glad that I don’t live on the “Pacific” ocean. The Atlantic is far more peaceful.
Mount St. Helens was enough of a teaching moment for me to take these kinds of things seriously.
