In many people’s minds, the Bay Area and earthquakes are inextricably linked. In the East Bay, the Hayward Fault (part of the larger San Andreas Fault system) runs 70-plus miles through densely populated cities such as: Richmond, El Cerrito, Berkeley (including directly through Cal’s football stadium), Oakland, San Leandro, Castro Valley, Hayward, Union City, Fremont, and San Jose. The last big earthquake along this fault was a magnitude 6.8 quake that hit in 1868, destroying the city of Hayward, killing five people and injuring thirty. Scientists studying the fault found that the past five major earthquakes affecting it occurred every 140 years or so. Using this data in a model, a large earthquake should have struck this fault around 2008. Many scientists still believe this fault will get a major quake in the next 30 years.

There are also several minor faults in this area. If geology is your thing, check out Las Trampas Regional Wilderness (Hike 33), as the park lies on the Las Trampas and Bollinger Faults.
