California has been struck by a fairly strong M5.0 (M4.6) earthquake which has currently broken out into a swarm along the San Andreas fault.

Above: November 13, 2017 – The expected near M5.0 earthquake and swarm struck in central California along the creeping section of the San Andreas Fault.


Please keep in mind, this weeks earthquake forecast called for a M5.0 to strike near Southern California.  The forecast was issued Sunday November 12, 2017.

Today, November 13, 2017 the expected earthquake struck in California.

The earthquake was fairly powerful, and was felt by many thousands of people across the region.  Thousands of shake reports were made to the USGS on their website, which indicates heavy surface movement occurred across Central California.

Felt Report – Tell Us!

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.
