A fault line beneath Lake Tahoe could rupture at any time and unleash a massive earthquake that triggers an underwater landslide and sends 30-foot waves crashing into nearby parks, campgrounds, homes and marinas, researchers said.
Such an event along the West Tahoe Fault, the biggest of Lake Tahoe's three geologic faults, could also send waves over a dam that regulates water flow into the Truckee River, according to research presented last week at a meeting of the American Geophysical Union in San Francisco.
The West Tahoe Fault, which skirts the lake's western shore and runs through Fallen Leaf Lake and beyond to the south, is large enough to deliver a temblor of magnitude 7 or higher, according to the researchers.
However, it's unclear when a large quake might strike. The last big earthquake along the fault appears to have occurred between 4,000 and 6,000 years ago, and the fault appears to produce major earthquakes every 5,000 to 7,000 years, according to the researchers.
Several more years of research is needed to determine the likelihood of a major earthquake on Lake Tahoe, according to the scientists from three universities - University of California at San Diego, San Diego State University and the University of Nevada at Reno - who are conducting the research.
They have conducted much of their research using a boat and a laboratory operated by the University of California at Davis.
Their research is designed to better understand the history of Lake Tahoe's earthquakes and the volatility of its fault lines.
The findings will likely make their way onto federal earthquake hazard maps that help determine building codes and set insurance rates.
"We're keeping an eye on it," said Michael Reichle, chief seismologist at the California Geological Survey. "There are active faults near the lake, under the lake and to the east in Nevada at the base of the hills. We still don't know very much about all those faults."
Nah. All the bigsh*ts with lake Tahoe property will successfully lobby against the earthquake.
Good thing my mother bought her place "up" from the Lake. Several hundred feet up.
Some beautiful views from up there, for sure. Pretty country.
As is always the case....
And generate more government grants to study it.
Wonder how long before they come out with one about this. If they could find a way to blame it on Bush...it would be on next Sunday night.
Let me know when CA slides into the Pacific.
Well we can all aspire to have been fortunate enough to have earned enough to afford lake property on Lake Tahoe. Unlesss we expect the government give it to us.
I do not see it as anything worthy of envy. Scenery is good, but the would-be neighbors already there are not.
Are they expecting Rosie O to take a skiing trip? I can see where a fall from her could set off the end of the world...
It's not nice to find fault with her!!!
Just don't forget... There's enough water stored in that very deep lake to flood CA's huge central valley to a depth of 1 foot!!!
Pelosi's fault.
Sounds as if you have just met the wrong people:)
Well then, Put a bore hole from the South East, under Heavenly Ski Resort, that comes up in the lake, and drain the thing if it is a hazard to human occupancy. Can't have any hazards now, especially waves from earth quakes. Send the water down to where it is needed, maybe Sacramento or Oakland.
Since Schwartzenegger has included the CA portion in the Sierra-Nevada GovernMental Land-Use CONservancy... Anything disastrous is no longer allowed to happen in such a GovernMental paradise. Especially one instituted by a pseudo Republican Governor!!!
This thread might as well be dead because none of this can possible happen now. It's all been prempted by GANG-GREEN groups and their Repellican Governator... SAFE!!!
Having actually read full reports of this nature (something I strongly suspect you've never done) months and even years of painstainking research go into something like this.
And there isn't exactly vast sums of money spent on this stuff - it's not the space program or building a fusion reactor.
Still continuously amazed at the crazed hatred of science and scientists around here.
