U.S. tsunami threat higher than thought (Ca, Or, Wa)

The threat of a devastating tsunami hitting the U.S. West Coast might be higher than previously thought, scientists say, based on a new study of earthquake faults off the coast of Alaska.

Tsunamis are often triggered by earthquakes, as was the case with the 2004 Indian Ocean tsunami, which was sparked by the 9.3-magnitude Sumatra-Andaman subduction quake in the same ocean. The tsunami killed nearly a quarter of a million people.

The new research suggests that future tsunamis could reach a scale far beyond that suffered in a 1964 tsunami generated by the great 9.2-magnitude Alaskan earthquake — "the most devastating seismic sea wave to impact the northwestern coast of the U.S. in historical time," said study team member Ron Bruhn, a geologist at the University of Utah.

IOW, you Westies are screwed.

Catch a wave ping.

This truck at Lowell Point, 2 miles from Seward, Alaska, was bent around a tree by the surge waves generated by the underwater landslides along the Seward waterfront. The truck was about 32 feet above water level at the time of the earthquake.

WEER DUMED.

The only disasters we have here in the center of Michigan are manmade. The epicenter is usually in Lansing.

WEER DUMED.

WEE R.

East coast could get hit. Collapsing volcanoes in the Atlantic. We’re all gonna die, again.

[Bigg Red]

Well, one would hope that there would be advance warning. Can’t prevent property loss, but it can save lives.

Isn’t a tsunami a tidal wave? Why don’t we just say tidal wave?

[allmost]

Frantic people clogging the escape routes. Don’t know how much warning is needed.

When it's not a tidal surge.

A few of these killer waves might help 0b0z0’s health care plans.

That question was not your high water, Mark.

Anybody got any idea where I might find some information regarding the predicted propagation of a Tsunami into Puget Sound?

I’m wondering... if there’s a Tsunami that comes across the Pacific and strikes the WA coast... how far will it ingress up the Straits and around into the sound? I don’t think Tsunamis turn corners very well, but they do a little bit... and there could be a channelling effect as it came throught the Strait of Juan de Fuca.

Curious...

Because there is nothing tidal about a wave generated by a large water displacement. Tidal bores such as the waves on the Amazon and Severn rivers are actual waves caused by the tide coming up a river this could be considered a tidal wave which is much different than a tsunami.

Yes, Obama could mandate that all senior citizen housing and nursing homes be situated on earthquake faults and high-risk coastal areas thus negating the need for mandatory meetings every five years for senior citizens where they’ll be asked to do everyone a favor and kill themselves.

I did a search on "tsunami puget sound" and got a bunch of hits.

Yah... I did too. Seems most of the studies seem to focus on propagation of a tsunami resulting from an quake on the Seattle fault, not so much a tsunami coming in from the sea. But the propagation patterns are interesting, and probably are a useful analog for how the waves will move around the sound.

[ThisLittleLightofMine]

Because it is the pacific ocean not the atlantic.

[ThisLittleLightofMine]

I was always told that but I guess I was wrong.

[Grampa Dave]

Careful don’t Rohm and the other 0b0z0 thugs any suggestions on how to handle the senior citizen health issues.

Careful don’t Rohm...

Thanks for the ping.

My pleasure. [waves]

What with quakes, tsunami’s and volcanoes . . . the beautiful Pacific NW could be in for some . . . interesting times . . . as the Chinese say.

I’ve got advance warning, I live in Kentucky (LOL).

Wrong! America always used the term tidal wave, which is not an accurate description of what we now know is actually happening. The ‘hate America’ crowd decided to use the Japanese term tsunami as an alternative. However, the term tsunami means harbor wave, which in my estimation is even more inaccurate that tidal wave.

[dirtymac]

Exactly! Because we now know that the term tidal wave does not accurately describe the event. So the hate America crowd decided to not use our term but use the Japanese term. Unfortunately the term tsunami means harbor wave, which is even more inaccurate than tidal wave. I am just pointing out the blatant hypocrisy of our ‘scientific’ community.

Surf’s up!
