Most dangerous 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 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.

The date Oct. 21, 2008, marks the 140th anniversary of the 1868 earthquake that had an approximate 7 magnitude. Now 2.5 million people live along the Hayward Fault and 7 million people in the region would feel a repeat event of the same magnitude.

The U.S. Geological Survey presented new studies to partners, colleagues and media at the American Geophysical Unions annual conference in San Francisco on Dec. 11. Scientists explained the significance of new high resolution elevation models, imagery of active deformation and creep, and new results of age-dating studies, plus ground motion simulations showing rupture along the fault.
