The National Science Foundation funded work reveals unexpected brine deposits beneath the seafloor near the fault, which could change the way we conceptualize oceanic transform faults. The Gofar fault ...

A fault line does not keep a calendar, no matter how often people ask it to. That simple limitation shapes nearly everything scientists say about the San Andreas Fault. Researchers can measure strain, ...

“Neither the USGS nor any other scientists have ever predicted a major earthquake.” That blunt reminder still frames the public conversation around the San Andreas fault more clearly than any dramatic ...

When we think of earthquakes, we imagine sudden, violent shaking. But deep beneath the Earth's surface, some faults move in near silence. These slow, shuffling slips and their accompanying hum -- ...

Scientists have warned that last year’s Ridgecrest quakes in Southern California have increased the risk of a major San Andreas Fault earthquake. The quakes, warn catastrophe modeling company Temblor, ...

Meet the San Andreas Fault’s newfound neighbor. Mapping deformations deep underground along the shoreline of a Southern California lake called the Salton Sea, seismologists discovered a fault that ...

The Hayward Fault, a long and lethal crack in the Earth, slices along the base of the Berkeley Hills and directly through the University of California. It passes under a theater and a couple of ...
