2 days agoWhich fault line do you live on? An earthquake guide for California.
The infamous San Andreas Fault Zone - a system with the main fault and many near-parallel faults - runs across much of California, dividing the Pacific tectonic plate from the North American one. The Pacific plate moves northwest about 2 inches per year, meaning Los Angeles is creeping toward San Francisco. The unsteady sliding between the two plates plays out in fits and starts. Sudden slips lead to earthquakes, which release the pent-up energy.
