1. Earthquake early warning summit April 4-5, 2011, UC Berkeley Delivering earthquake warnings to the U.S. west coast

2. Why we are here… The U.S. west coast is a tectonic plate boundary Therefore we must be ready for big earthquakes North-south divide in the character of the earthquakes

3. Why we are here… The U.S. west coast is a tectonic plate boundary Therefore 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

4. Why we are here… To the south: San Andreas Fault Network of onshore and offshore faults, including the Hayward Fault Expect an earthquake similar to 1995 Kobe earthquake: 6000 fatalities, $100 billion losses

7. Summit resolution Yesterday University and government scientists from: Caltech Central Washington University Stanford Southern California Earthquake Center UC Berkeley UC San Diego University of Washington U.S. Geological Survey 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
