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.

If you go up the Coos River, you can find indications of a big tsunami by digging in the hillside above the river by sixty to eighty feet. The hillside was drastically eroded and logs were buried well up above the rivers bed. It seems likely that parts of North Bend and Coos Bay were washed over by the wave.
Fly over country voter don’t count,fema could care less.
There are lots of events in Yellowstone....Old Faithful blows regularly (LOL)...no really. When we were there for a week, the park employees told us, and I’ve read other places since, that it is way overdue....there’s lots of bulging and bubbling places there...ready to move...
Who do you think is going to evacuate and resettle millions of people in a natural ( or unnatural ) disaster?
Do you think the plans to do so need never be tested and tried In an exercise?
Or maybe you believe Jade Helm is about Obama preparing our diminishing military to enter another land war in the Middle East- yeah, that makes sense. All the ammo purchased by the federal Govt is so we can send civilian agencies to a foreign war
Mount Rainier is near the top of the lists for major disasters waiting to happen. It would be small compared to the “big one” in the PNW. As another poster mentioned, the New Madrid fault would be way worse than Cascadia. Back in the 1800’s the New Mardrid eq rang church bells in Boston! And lots of pipelines that run from Texas and feed the NE run through the area.
I’m in the PNW and it WILL be a huge disaster. The local state seismic guy and some other bureaucrat were down-playing the article, but I am guessing that Seattle, which can only be accessed by bridges, will be an island unto itself for quite awhile with probably all of the bridges destroyed if it is a 9.0.
There is a fault scarp visible at a golf course west of Seattle from the last big one (1700). It is 20’ tall. That is a lot of movement to happen all at once!
As a matter of fact, my youngest daughter asked me that very question this evening at dinner when we were talking about this article.
I really didn't know how to answer her.
New Madrid Fault. They’ve been running exercises for the last few years.

Just so it gets Portland
They will blame it on global warming :)
Some of that might be tsunami. But the dead stumps and sand indicate that the coastline dropped in elevation into the ocean. By quite a bit - 10 to 20 feet iirc. Imagine what happens if you take miles of coastline and lower it 20 feet in 10 minutes!
BTW - this news is nothing new. It has been in the geology community for at least 15-20 years. And in the local papers since 2001 when we had the Nisqually eq, and lots of people woke up to the fact of what a large eq can do.
And it WILL happen. Who knows when, but when it does, it will happen in an instant. Be prepared.
Yeah the coast did drop but this is up the river several miles. There are beaches where sand erosion exposes tree stumps that were well above the water line at one time. The upper edge of the subduction zone sank when the earthquake released the tension on the upper side of the fault. The same thing happened at points in the Great Alaska Earthquake. Land settling is common but unpredictable at this point. If we could map and quantify the stress on different sections of the fault, it would help preparations greatly.

"We are awaiting more information from [Seattle Tunnel Partners] about their projected schedule, so we expect to have more information to release within the coming weeks," spokesperson for the tunnel project Laura Newborn said in an email.
With June come and gone, it's now been about a month since new information regarding Bertha the tunnel boring machine has been provided. Repairs on the machine continued in early June, including the installation of a new seal system. Repairs began in April.
The $1.35 billion project is expected to resume in August. The project is part of the $3 billion viaduct replacement program. The tunnel project is already about two years behind schedule. As of March 3 it traveled 1,083 of the needed 9,270 feet.
Before the project's tunnel review panel was eliminated by the Legislature, it reported that the most significant risk to the project was Bertha itself.
"This will remain as the single most significant project risk until the tunnel boring machine breaks through at the north end of the tunnel alignment," the report states.
SOunds like a leftard man-made hole to throw money in to.
Ummm...100 miles east of the ocean and at 3000 ft elevation...I think I’m good. Made it through the Landers/Big Bear quake with only some broken crockery.
Boston big dig part deux.
Jade Helm is SpecOps .. and I seriously doubt they will be doing any evacuating or settling of people.
They will be busy looking after all their own people.
Mount Rainer is a dormant volcano, as was/is mt. St. Helens. Mt Rainer would most likely, according to scientists, produce huge mud flows moving toward Tacoma area. Pretty much wipe out everything in its path. I must say, mt Rainer is a beautiful mountain.
Once uranium is processed to the degree necessary for a nuke it starts emitting tritium. That cannot be hidden.
Israel will bomb them the day after that is discovered. They won’t have a chance to put it in a bomb.
Suggest reading the article. It happens, on average, at the 243 year mark. Thus, we are ~35% past the average.
New one on me, I thought it was Yellowstone in Wyoming that had the magma under it, not Yosemite in California.
