Geophysicists at the University of California, Riverside have received a $4.6 million grant from the National Science Foundation to study the dynamics of earthquake fault systems. Such systems occur ...

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 ...

A groundbreaking 1,000-year simulation reveals tectonic stress along the San Andreas and San Jacinto faults has reached a ...

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 ...

Earthquake early warning times for a magnitude-9 event with an epicenter in southern Oregon. With a lower alert threshold (left) some locations closest to the source feel the ground shake before the ...

Stress levels beneath Southern California’s two most dangerous fault systems have climbed to their highest in at least 1,000 ...
