The M4.6 (M5.0) earthquake struck Central California on the creeping section of the San Andreas fault, and has been accompanied by a swarm of several smaller events in the same location along the fault.

This new larger earthquake , and accompanying seismic swarm means the “creep” of the fault, or the “plate movement” of the fault is picking up in pace.

With the ‘slow slip’ of the plate boundary now taking place from Southern California (Anza Gap) all the way North to Seattle, a potential for larger movement on the West coast is not only present but a substantial risk over the next week.

Above: November 12, 2017 – University of Washington realtime tremor map shows clusters of tremors across three states all within 48 hours , indicating a full plate slow slip event is underway from Seattle to Southern California near Anza Gap.
