Over the past 48 hours the whole of the West coast of the United States has moved on at least a 4.0 magnitude level or greater. Currently, another mid-4.0 magnitude (4.2 M) earthquake has struck the West coast, off the shores of Oregon, near the Axial undersea volcano (which is currently erupting). This is a huge development to see, please pay close attention to the regional seismic activity over the next week (currently May 22 2015). This new West coast earthquake activity is expected, but unwelcome. 

See the earthquake forecast for the West coast of the United States here (issued May 21 2015): This new West coast earthquake unrest began with a 4.2M at the border of Alaska and British Colombia Canada (as expected). The Alaska activity was shortly followed by a new swarm of earthquakes at the Salton Sea Volcanic buttes (located in Southern California). The Southern California volcanic earthquake swarm was shortly followed by a 4.1M event in Napa Vallay / Gorda Escarpment zone near San Francisco, CA.
