Stress on the San Andreas fault is at a 1,000-year high, a new study finds

• Tectonic stress on Southern California's San Andreas and San Jacinto faults has climbed to its highest level in 1,000 years, a new study finds, leaving the system in what the researchers call a 'critically loaded state.' The scientists are careful to stress what the finding is not: a prediction of when the next Big One will strike, because earthquakes still cannot be predicted.
