• The Hayward Fault: A Tectonic Timebomb

  19 years ago the 6.9 Loma Prieta earthquake was a stark reminder that we live in earthquake country. Even though we generally are aloof to the possibility of a major temblor, the reality is we are surrounded by active faults and one East Bay faultline has geologists particularly worried.

  You probably know that the San Andreas Fault runs nearly the length of the state. But did you know that you can see the fault for yourself? Take a hike at Los Trancos Open Space Preserve in the Santa Cruz Mountains above Palo Alto.

  It was 140 years ago, in October 1868, that the Hayward Fault unleashed the magnitude 6.8 temblor that put the fault on the map. The quake shook the entire region and virtually leveled the then-small hamlets of Hayward and San Leandro. Now, the land along the fault line is among the most densely populated in the region, a sobering situation given the likelihood of a repeat performance in the near future.
