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.

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.
WEE R.
East coast could get hit. Collapsing volcanoes in the Atlantic. We’re all gonna die, again.
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?
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.
Eat, bookmark and be merry.
And according to Al Gore, New York, Oh Nozzzzze!
Who is the “Tsunami Czar”?
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.
