Hawaii Study Warns San Andreas–San Jacinto System Near 1,000-Year Stress Peak

New research from the University of Hawaii at Manoa finds stress along the San Andreas and San Jacinto faults at the highest levels in 1,000 years, suggesting a greater chance of a large, possibly joint rupture and noting Cajon Pass as a potential 'earthquake gate' that could either block or enable ruptures into both fault systems, with major Southern California cities like Los Angeles at risk.
