What
New research suggests that a critical junction of the San Andreas and San Jacinto fault systems, just 50 miles from downtown Los Angeles, has accumulated stress levels matching 1,000-year highs.
When
Tue, 16 Jun 2026 23:54:00 GMT · 10d 5h ago
Where
Cajon Pass, California, United States ·
Why
It has been over 100 years since these faults produced a major earthquake, allowing tectonic stress to build significantly in key areas.
The Frontline Impact
How this affects you
The accumulation of stress in these fault lines increases the likelihood of a dangerous earthquake that could be catastrophic for one of the most densely populated areas in the U.S., potentially spreading across multiple fault systems if it originates in Cajon Pass.
