Multiple fault lines increase earthquake risk in California

Guardian : Although California is known for its frequent earthquakes along the San Andreas Fault, another large nearby fault could add to the threat. Julian Lozos of California State University, Northridge, has found that at least one of the state’s larger earthquakes, which occurred in 1812, was probably the result of both the San Andreas and San Jacinto faults rupturing at the same time. The earthquake caused damage as far north as San Buenaventura and as far south as San Diego. Lozos pinned the devastating event on both faults after analyzing historical records and geological evidence collected directly at the fault lines. He warns that similar joint ruptures are possible in the future, and he hopes that better understanding of the danger can help people better prepare for it.
