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 dangerous millennial high, threatening LA with a 7.5+ mega-quake.

PORTLAND, Ore. — Portland State University researchers simulated an earthquake on Friday, testing the effectiveness of a potentially revolutionary soil treatment. Researchers used a mobile field ...

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 ...

Residents along the West Coast were left shaken when a 7.0 magnitude earthquake rattled the region last week, resulting in a tsunami warning and a scary couple of hours for more than 5 million people.

A new study suggests stress levels along Southern California's San Andreas and San Jacinto fault systems are at their highest point in 1,000 years, placing the region in a "critically loaded state." ...
