Recent research indicates that the San Andreas and San Jacinto fault systems in Southern California have reached their peak tectonic stress in a millennium, heightening fears of a potential multi-fault earthquake. Experts suggest that Cajon Pass may serve as an 'earthquake gate,' potentially either preventing or allowing a rupture to spread across fault lines. This threat could impact Los Angeles, San Bernardino, Riverside, and the Coachella Valley, where vital highways, railways, and energy routes are at risk. Scientists emphasize this is not a prediction of an earthquake, but rather a call for immediate readiness.
