The Hayward fault, part of the larger San Andreas fault system, runs 74 miles through the East Bay of the San Francisco Bay Area. The fault is overdue for an earthquake that could cause extensive ...

In computer simulations of the Big One—a large-magnitude earthquake that may occur along the San Andreas Fault in California—seismic waves ripple from the epicenter of a magnitude 7.8 earthquake near ...

The Hayward fault line has not had a major earthquake since 1868, but new simulations designed by Lawrence Livermore National Laboratory and Lawrence Berkeley National Laboratory have found the Bay ...

According to Ceferino, preliminary findings showed that people’s responses were not linear. “The risk perception at some point increases dramatically because things are falling and the shaking is so ...

Sustained supershear earthquake ruptures produce distinct ground-motion characteristics compared with subshear earthquakes, according to a study published in the Bulletin of the Seismological Society ...

An earthquake typically sets off ruptures that ripple out from its underground origins. But on rare occasions, seismologists have observed quakes that reverse course, further shaking up areas that ...

On January 1, 2008, at 1:59 am in Calipatria, California, an earthquake happened. You haven’t heard of this earthquake; even if you had been living in Calipatria, you wouldn’t have felt anything. It ...
