"We talk loosely about faults being 'overdue,' but it's important to see a physics-based estimate that the system is sitting at a 1,000-year high." Scientists have discovered that the southern portion ...

A new study found that California's San Andreas Fault has reached its highest stress level in the last 1,000 years. From the desert of Palm Springs to the San Francisco Bay Area, the 800-mile fault ...

Stress accumulating in the southern San Andreas fault. (Burkhard et. al., J. Geophys. Res. Solid Earth, 2026) It's called California's Big One for a reason. For more than a century, tectonic pressure ...

Stress on the San Andreas Fault System has reached a 1,000-year high, according to new research from the University of Hawaii. Higher stress on a fault means the pressure that causes earthquakes is ...

The ground north and east of Los Angeles holds one of Southern California’s most uneasy meeting points. At Cajon Pass, the San Andreas and San Jacinto fault systems crowd together in a tectonic ...
