An earthquake is overdue along Southern California’s “critically stressed” San Andreas and San Jacinto faults, according to a new study.
As stress builds on a fault over centuries, it builds pressure that has to be released in an earthquake. In the study, scientists found that the San Andreas and San Jacinto faults are under more stress than at any point in the last 1,000 years, meaning that a massive earthquake could be on the way.
“Because it’s been quite a long time since the Southern San Andreas or the San Jacinto have had a large earthquake, we’ve accumulated a lot of stress,” said Kate Scharer, a co-author of the study and a geologist with the U.S. Geological Survey…
