What
A new study found that stress along Southern California's San Andreas and San Jacinto faults has reached its highest point in 1,000 years.
When
Tue, 16 Jun 2026 22:08:35 GMT · 1h 47m ago
Where
Southern California, Los Angeles, San Bernardino, Riverside, Coachella Valley, Cajon Pass ·
Why
Stress levels on multiple fault segments are now at or above the highest values seen in the past millennium, and more than 160 years have elapsed since the last major rupture.
The Frontline Impact
How this affects you
The unprecedented stress levels on the San Andreas and San Jacinto faults in Southern California could lead to a large rupture involving both fault systems, potentially causing significantly more damage in densely populated areas like Los Angeles than a single-fault event. This puts approximately 13 million people in the greater Los Angeles region at increased risk.
