Tensional faults, on which the magnitude-4.6 occurred, run approximately NNE-SSW and transfer plate motion from the Imperial Fault to the San Andreas. So far, the earthquakes in the Salton Sea Swarm have not migrated onto the San Andreas, but they are close to a southern extension of San Andreas into the Salton Sea. Credit: Temblor.
