Why
Researchers found that stress levels on multiple fault segments are now at or above the highest values seen in the past millennium, suggesting the region may be capable of a large through-going rupture involving both fault systems.
The Frontline Impact
How this affects you
A major earthquake involving both the San Andreas and San Jacinto faults could devastate Southern California, impacting several major cities. This research helps urban planners and policymakers prepare for potential seismic events.
