Earthquake early warning summitApril 4-5, 2011, UC Berkeley
Delivering earthquake warnings to the U.S. west
coast
Why we are here…The U.S. west coast is a tectonic plate boundaryTherefore we must be ready for big earthquakes
North-south divide in the character of
the earthquakes
Why we are here…The U.S. west coast is a tectonic plate boundaryTherefore we must be ready for big earthquakes
To the north: subduction zone A magnitude 9 earthquake
similar to the one that just occurred in Japan is possible
Why we are here…
To the south: San Andreas FaultNetwork of onshore and offshore faults, including the Hayward FaultExpect an earthquake similar to 1995 Kobe earthquake: 6000 fatalities, $100 billion losses

Warnings can be provided before earthquake shaking
Warnings complement good buildings and planning
In the recent M9 earthquake in Japan a warning was successfully issued in the region of strongest shaking
Areas for improvement of the Japanese system have been identified
Testing of a warning system in the US has been ongoing. Now it the time for broader engagement of users.Sustained and enhanced funding is needed to make warnings a reality
