Scientists find an “earthquake gate” as California fault stress hits a 1,000-year high

Researchers say stress on Southern California’s San Andreas and San Jacinto faults has reached some of the highest levels seen in a 1,000-year simulation. Because both faults are highly stressed at the same time, the Cajon Pass junction may be increasingly primed for a rupture that could cross both systems, although the study does not predict when an earthquake will happen.
