Computer error signals erroneous report of earthquake in Northern
California

SAN FRANCISCO - The U.S. Geological Survey says a computer at its
Berkeley station mistakenly concluded the Napa area of Northern
California had been hit by a magnitude-5.0 earthquake.
Richard Buckmaster, a geophysicist at the agency's National Earthquake
Reporting Center, says officials are trying to determine why the
computer generated the "dubious or erroneous" alert Friday.
He says the centre's equipment saw no evidence that Napa had
experienced even a much smaller quake.
The false alarm created a flurry of activity for earthquake watchers
and news media but otherwise disappeared from the USGS system with the
strike of a delete button.
Buckmaster says such inaccurate reports are rare in California.
