WASHINGTON Using sophisticated seismometers and GPS devices, scientists have been able to track minute movements along two massive tectonic plates colliding 25 miles or so underneath Washington state's Puget Sound basin.

By comparison, the largest earthquake ever recorded was 9.5 on the Richter scale, in Chile in 1960. The largest in North America was the 9.2 Great Alaska Earthquake in 1964, which killed nine people and spawned a tsunami that struck the Northwest coast. The 1906 San Francisco earthquake, which killed 750 to 2,500 people, was estimated to be an 8.2.

Did I leave anyone or anything out?
We’re all gonna DIE ping!
Cheers!

Yea you left out Rush. You know how he is on mother nature.
Del, you and Velveeta - even Maurice - are phockhosed....finito.
You forgot white, angry, Christian males.

No problem, they will float with all of their puffed up self importance.
Why is it that liberals gravitate towards earthquake zones?
Must be all that caffeine.
Don’t forget Sugar and Spice and Everything Nice are now on the

The article said, in part...
The last mega-thrust earthquake along the Cascadia subduction zone, estimated at 9.2, was in January 1700 . It produced a tsunami that reached Japan . Cascadia subduction zone mega-thrust earthquakes happen on average every 400 to 500 years, but they can happen as little as 300 years apart or as much as 800.

Since the deep tremors were first detected 15 years ago, scientists have been trying to determine what was causing them along the Cascadia subduction zone. Eventually, they concluded that the tremors reflected the slippage of the Juan de Fuca plate under the North American plate.
I remember when the scientists discovered the huge earthquakes from the Cascadia subduction zone, from when I was in Portland (at the time). Shortly thereafter, I saw the freeway bridges getting retrofitted with cable anchors to keep them from tumbling down in such an earthquake.
Now, it seems all along that area (of the Cascadia subduction zone) it’s possible to have an earthquake of “possibly” up to a magnitude 10, or at least larger than any earthquake recorded in US history in the lower 48.
I was reading articles in the paper on how Portland would turn into “two cities” (instead of being just one) after such an earthquake (because the two halves are joined by a lot of bridges).
The two largest earthquakes in US history (in the lower 48) were not in California (not even the San Francisco one) but from the New Madrid fault in the middle of the US, which supposedly made the Mississippi River flow backwards for a short while.
Oh..., and also, it wouldn’t pay to live on the coast of Oregon, if it were to happen right offshore. It might produce a 100-foot tsunami, which would be about impossible to get away from... hoo-boy!
Sandy, I wish you well and when it hit’s, feel free to find a way to ping me and I help you out.
I live in PA, about a 3 hour drive to the west of Seattle. I’m at the top of my mountain and will be able to see the Straights rise from my house.
I figure that I’ll be able to collect some nice stuff from our beaches as the tide goes back out... this could be fun.

Yes, assault weapons.
Only if you are in Seattle.....Oh! Sorry. (:o)
Un til the pyraclastic flow from Mt Rainier surrounds your mountain, you might be safe
