Fresh warnings over 'The Big One' as study finds seafloor sediments off the Pacific Northwest could unleash a megaquake

[DP]

Whew! Long headline. Anyone in the PNW read this? Or is it the same old, same old...

The threat of ‘The Big One’ has long loomed over the Pacific Northwest, where several major cities from Vancouver down to northern California are cradled by the 620-mile-long Cascadia Subduction Zone.
The geological record shows the area is due for a major earthquake, which would likely be followed by a massive tsunami.
Now, a new study has confirmed the region just off the coast of Washington has the ingredients for a megaquake.

In the study, led by a team at the University of Texas at Austin, researchers found that such a quake may be more likely to strike off the coast of Washington and northern Oregon than regions further south along the subduction zone.

I've been reading about the big one in the PNW for years. It's overdue, and when it happens pretty much no one is prepared or can escape it if they're west of the Cascades. if it's big enough, perhaps it will cause problems east of the Cascades too, but I choose not think about that. There was an article in Outside Magazine about 5-10 years ago that covered this pretty thoroughly. The casualty count would be in the hundreds of thousands within hours of the quakenami.

Just watch a few videos of the Fukishima quake and wave, wont take much convincing.

.....is this the 'Big One' that Kirstie Alley was referring to in her thank you speech [ with regard to her then husband Parker Stevenson - 'Hardy Boy' ].......???

Old news.
Click bait.

Next will be a "new" report about the Yellowstone Supervolcano.
Either disaster, I'm screwed.

Que sera, sera.

Excellent read, thanks for posting it.

My stepbrother used to live in San Jose, CA. He would give me grief about living in Florida with all the hurricanes. my answer was simple - at least I didn't have to worry about waking up at a new address.

Good read, the article won a Pulitzer.

Living at the south end of the Cascadia "zone" and the north end of the "san andreas" zone, and west of the Gorda plate "triple junction"... this is not news, really.

The Cascadia zone is capable of 9-point quakes, along HUNDREDS of miles of the subduction fault at once. Think Indonesia 2004, only bigger and more populated.

If a quake like that happens, and you hear about it on the radio, and you're near a coast anywhere on the pacific rim? Get to high ground immediately...
A few years ago when house hunting, I passed up a place about 200 yards from the bay. This was one of the reasons (well, it being $20,000 higher than my budget was another reason).

Count on MINUTES before the wave hits the West Coast.

If it happens in our lifetime, well, it will be worse than anything this country hass seen in 250 years, wth the possible exception of the Civil War.
