If a giant magnitude 9 earthquake strikes someday along the coast of the Pacific Northwest, or if, against all odds, an errant asteroid plunges into the ocean many miles off California, a monstrous tsunami could drown low- lying lands all up and down the continent's western edge -- and now a UC Santa Cruz scientist has calculated the sweep of such an event.....
...To model the event's effects, Ward assumes that in a huge quake on the Cascadia subduction zone, the two crustal plates would abruptly slip apart vertically by at least 50 feet in three successive blocks from south to north, generating a 9.2 magnitude quake. Aside from enormous quake damage on land for hundreds of miles, Ward estimates the resulting tsunami would pile a wave more than 20 feet high crashing onto the Oregon-Washington coast, inundating Seattle and the entire Puget Sound region as well as Portland and the mouth of the Columbia River.

Well, then I guess I'm not moving there. Way too dangerous.
BTW, what makes the asteroid "errant"? How does the author know the correct course?
What is this "Oregon" I keep hearing about?
"If Big Quake Hits off Coast, Tsunami Could be Gigantic (Washington, Oregon, California)"
A 20 foot wave would not be "Gigantic". I saw a Discover or History program earlier this year that talked about the effects of a huge landslide off of an island off the coast of Africa -- this would result in a 300 FOOT TSUNAMI hitting the East Coast of the US.
Now THAT would be GIGANTIC.
Dang, Freeprs are so negative.
There is no disaster that cannot have an opportunity. Think about it.
If you acquire ocean front property, maybe we could all come for a weekend bbq... how about if everyone brings beer and goodies from their own towns? That will be fun.
You can't fool me. I've never met anyone who has.
Oh well.
Veto in Puget Sound
Now cut that out.....
I'm with you but add the freaks & crazies in Seattle. So where's the problem?
Viva Marina Las Vegas!!!!
The author is "errant". :)
But if Congress is going to pass a law against eathquakes/tsunamis/hurricanes/asteroids/etc - we'll be just fine. All they need is some funding.....
Also, the following needs to be said......Bush's fault, minorities, children most affected.
sounds good to me. When the tsunami happens I'll ping ya to send out the invites. :o)
Thanks CH. I'l check it out and then see of CA has one since that's were I am. But the gov site should be about the same, right?
There was a 200 foot Tsunami in some Alaska inlet and there were witnesses. A small fishing boat went for a ride.
A landslide (actually a portion of a mountain broke off) into the head of the inlet created a 200 foot wave. And it wasn't the first time it's happened.
Discovery Channel had a program about it.
Thanks for the reminder about the tsunami flooding Portland too. Tidal affects are found all the way up the Columbia and Willamete rivers past Portland to Oregon City.
I don't see a problem here.
