5/03/2015 — 4.0M earthquake strikes San Francisco Northern California

After the announcement of a new volcanic eruption off the West coast of Oregon this past week (May 1 2015), we are now beginning to see seismic movement occur in adjacent areas to this volcanic upheaval.

A magnitude 4.0 earthquake has struck near downtown San Francisco California.

This movement in Northern and Southern California , which was forecast to happen, has now begun to occur in the expected areas.

This morning (May 3 2015), a series of earthquakes struck at a Los Angeles , CA fracking operations located in downtown LA, and in downtown Dallas Texas.   These fracking operation earthquakes, were accompanied by an earthquake at a dormant volcanic complex near Mono Lake, CA.

Now this 4.0 magnitude (and subsequent earthquake swarm) strikes the Northern area experiencing seismic stress, the Bay Area of San Francisco.

This Northern seismic stress has been building over the past 2 weeks, and has shown up via multiple steam plume events occurring at dormant volcanoes, hot springs, and cold springs.  Also multiple earthquakes at volcanic locations.

Over the past 2 weeks, we saw a 5.5 magnitude strike off the shores of Northern California directly along the Gorda escarpment, and an additional 6.2 magnitude event off the shores of Vancouver BC.
