Medium to large quakes peak every three years on central San Andreas Fault

Researchers found a periodic increase in slip rate every three years along the northern half of the central San Andreas Fault, indicating a higher probability of moderate to large quakes. This cycle is characterized by an upswing of microquakes, followed by moderate to large earthquakes six to seven times more likely to occur.
