Update Apr 6: Report on the event from the Chronicle

Today at 2 p.m., U.C. Berkeley will webcast a media briefing by “leading West Coast seismologists who will discuss their recommendations for establishing an earthquake early warning system in California, Oregon and Washington.”

From the media advisory:

Earthquake scientists from Washington, Oregon and California are meeting today and tomorrow, April 4 -5, to discuss the feasibility of establishing an earthquake early warning system for the West Coast similar to the one that gave a valuable heads-up in the recent giant quake in Japan. Such a system would place seismic monitors in a dense arrangement in fault zones and could begin sending warnings of impending ground-shaking within five seconds after an earthquake is detected by the nearest seismometer.

“Japan’s earthquake early warning system undoubtedly saved thousands of lives, and will reduce the long-term impact of the earthquake on the economy,” said Allen, who has been working for nearly a decade to develop and test an earthquake early warning system in the United States. “A similar system in California could provide as much as a minute warning – and in Washington, as much as two-to-three minutes’ warning – so that some actions, many of them automated, can be taken before the destructive waves arrive.”

Even a warning of 30 seconds could be enough for a doctor to halt surgery, a factory to shut down sensitive equipment, for a train to stop before it reaches a vulnerable bridge or prevent airplanes from landing or taking off. That could save many lives and potentially prevent millions of dollars in damage, Allen said.
