California's Hayward Fault Revealed: Most Dangerous Urban Fault In America?

As the 140th Anniversary of the last big earthquake on the Hayward Fault approaches, new U.S. Geological Survey studies provide mounting evidence that the San Francisco Bay Area should get ready for another big quake soon. The Hayward Fault has ruptured about every 140 years for its previous five large earthquakes. October 21, 2008, marks the 140th Anniversary of the 1868 approximate Magnitude 7 earthquake. Two and half million people now live along the Hayward Fault and seven million people in the region would feel a repeat event of the same magnitude.
