A noteworthy series of earthquakes has struck off the West coast of the United States, along the Gorda Escarpment off the shores of Northwest California.
Within another few minutes, the pressure transferred East by Southeast, causing a M3.0 (M2.9 revised) near the Nevada / California border. The smaller event pressing Eastward , releasing near several volcanic fields located around Hawthorne Nevada.

This movement along the coast of NW California was discussed as a possibility in the most recent earthquake update issued 8 days ago on January 21st.
See the video report here:
_______
We now need to be on watch across the Western , Northwestern, Southern, Central, and Eastern portions of the edge of the craton.
We always see movement to the East AFTER we see movement along the West coast. Usually similar magnitudes strike to the East (sometimes 1 magnitude less) along the edge of the craton.
Fracking operations, drilling / injection / pumping operations, deep mines, aquifers, dormant volcanoes usually all show activity AFTER movement off the West coast.
Challis Idaho, Yellowstone / Wyoming, Southern Colorado, Northern Arizona, West , East + North Texas, Oklahoma, Kansas, New Madrid Seismic Zone, Alabama, Mississippi, North + South Carolina, Virginia... not to mention New England (with the mystery booms and rumbles) ....... all these aforementioned areas need to be on watch for movement following this size of activity off the West coast of the USA.
