1906 Earthquake Centennial Preparing for the Next Big one

The last great earthquake in the Bay Area was the April 18, 1906 San Francisco Earthquake. These large earthquakes happen in cycles: the fault becomes locked and does not move for a period of about 150 years and then breaks in a catastrophic earthquake.

The question is not IF the next big one will occur, but WHEN. The probability is 62% for a magnitude 6.7 or greater earthquake occurring in the Bay Area in the next 30 years.

The USGS [http://pubs.usgs.gov/gip/2005/15/] offers an excellent pamphlet on how to prepare for the next big one. Please take the time to review it.

The Association of Bay Area Governments (ABAG) [http://www.abag.ca.gov/bayarea/eqmaps/] provides shaking intensity maps with enough detail to determine how well your neighborhood will do during the next big one.
