The past week of earthquakes (up to May 8, 2015) reveals tremendous seismic pressure building in the Southwest / West coast of the United States.
________
On top of all the other dormant volcanic activity happening globally, such as ancient volcanoes waking up in Japan after 800 years of silence, and unexpected eruptions in Chile — we now are seeing movement begin around MULTIPLE dormant volcanoes along the West coast of the United States.
This comes on top of the news of a fresh underwater eruption occurring off the West coast of Oregon.
Most recently, now we see earthquake movement directly at Mono Lake Supervolcano, which is located in Central Eastern California, along the Nevada border.
________
Information on this event at Mono Lake from the USGS:

________
If this movement at Mono Lake, CA was on its own, then we might say it was just “chance” or “coincidence”….. or maybe we might incorrectly think it was just “normal” small seismic activity which one might see at a time of global seismic unrest elsewhere.
But if you knew about the OTHER dormant volcanoes which showed movement this past week, then you might reconsider your definition of “normal”, and thus reconsider what we might be observing take place along the West Coast.
9 out of the 10 past most recent earthquakes on the West coast were DIRECTLY at volcanic locations.
Recent examples below.
