Scientists may be cracking mystery of big 1872 earthquake

Geologists may be close to cracking one of the biggest seismological mysteries in the Pacific Northwest: the origin of a powerful earthquake that rattled seven states and provinces when Ulysses S. Grant was president.

Preliminary evidence points to a newly discovered fault near the town of Entiat in Chelan County, Wash. The find adds to a growing body of evidence that Central and Eastern Washington are more quake-prone than previously thought, and will help refine seismic risks in an area that's home to 1.5 million people, more than a dozen hydropower dams and the Hanford nuclear reservation, said Craig Weaver, regional chief of the U.S. Geological Survey's earthquake programs

At the source, there are some interesting written accounts from the time of the earthquake. Be careful when you say you don't live in an earthquake zone!

[JimSEA]

Possibly of some interest.

[Darksheare]

Not my fault.

[cogito3]

Bush’s fault, of course.

[Red Badger]

FRACKING?...................

[wally_bert]

How about Doctor Loveless? Maybe he had a hand in it too.

You don't want to know, Mr. President...

[Darksheare]

No, no.
SUV’s and logging.
And McDonalds not having calorie labels.
Obviously.

The Last Cascadia Great Earthquake and Tsunami; 313 Years and Ticking

We now know a ~magnitude 9 earthquake struck our region on January 26, 1700 at ~9:00 PM.

Neat!

Seems though that it's a little late to do anything about the dams and nuclear facilities that are already there. Looks like Hanford nuclear site is 100 miles SE of the epicenter.

[Red Badger]

9:00 PM?

Was that Pacific Standard time?...............8^)

[Darksheare]

Or them bigfeets out there squatchin around!

(Sidenote, there is a small faultline to my west. It jiggled a bit when that one quake hit upper NY a few years back. Shook the house we were in a bit.)

[thackney]

Yep.

Most of the time is calculated off the written records of the arrival time in Japan of the Tsunami.

We're going to need a big push to
wrap this up. Let's git 'er done.

[Zathras]

The most dangerous fault in the USA.
A sizable quake would damage Seattle, Vancouver and much of the Oregon coast

[Flag_This]

"The most dangerous fault in the USA."

More dangerous than New Madrid?

[Lurker]

“The most dangerous fault in the USA.”

Actually that would be New Madrid.

[Jonah Hex]

"I admit it, it's my fault!"

[JimSEA]

We have an unfortunately short attention span. That 1700 tsunami always nags at the back of my mind when we drive over to the Oregon coast.
