9/25/2014 -- California SUPERVOLCANO Earthquake Swarm -- Mono Lake / Mammoth Mountain 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. The whole volcanic complex is known as the Long Valley Caldera. Originally formed 760,000 years ago, supposedly erupting every 200,000 years. 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.
