New Horizons in Science

The Hayward fault runs through Berkeley, Oakland, the Oakland zoo, Hayward and Fremont. For nearly a millennium, researchers have now determined, it has been the site of severe earthquakes every 140 years. The last one was in 1868. (Do the math.) Thomas Brocher will walk us along the fault with new data from an airborne laser, and show us a "shake map" of damage from the 1868 quake, when the population of the Bay Area was 260,000. It is now 7 million.
