California's Faults at a 1,000-Year Stress High
13:02
By reconstructing a millennium of earthquake history, a University of Bern team finds the San Andreas and San Jacinto faults at unprecedented stress levels. Using Coulomb failure stress, they show faults act as a coupled system that can transfer force and trigger multi-fault ruptures, as seen at the Cajon Pass gate. The takeaway is sober but practical: elevated long-term risk, normal recent…
