September 25th into 26th, 2014
A noteworthy earthquake swarm began a few hours ago ( late afternoon September 25 2014 ) at the base of Mammoth Mountain, located on the flank of the Mono Lake California supervolcano caldera.
So far, as of 5am PDT, there have been over 500 separate small earthquakes at this location.
Screenshot below shows the 2.5M+ events up to 2am PDT:
The whole volcanic complex is known as the “Long Valley Caldera”. Originally formed 760,000 years ago, supposedly erupting every 200,000 years.
New activity being monitored starting in 2014.
Quote the USGS..
“In July 2014, USGS Scientists Peter Kelly (Cascades Volcano Observatory) and Stuart Wilkinson (California Volcano Observatory) installed an automated volcanic-gas monitoring station on Mammoth Mountain, located on the SW rim of Long Valley Caldera (CA). The station tracks the temperature and concentrations of carbon dioxide and other gases at a steaming vent high on the north flank of the mountain known as Mammoth Mountain Fumarole.”
In 1980, the volcano experienced uplift and major movement, ironically very close to the same time as the eruption of Mt. Saint Helens.
Today, in 2014, this past week, we saw movement at Mt. Saint Helens, Yellowstone, and several other dormant volcanoes in California, Nevada, and Arizona.
This is ON TOP of the movement at Mount Shasta California , resulting in a glacier fracture mudslide earlier this week, and in addition to last months major earthquake in Napa, CA.

I covered the recent volcanic activity in my most recent earthquake post. Watch the update here:
Also, worthy to note the multiple 6.0M+ movement occurring internationally. Alaska on the NW edge of the craton, showing major pressure building.
