In addition to the larger movement in the Pacific Northwest, there were multiple earthquakes which struck near “Red Mountain” Volcano in Central East California.

Screenshots below from Google Earth show the multiple dormant volcanoes located near this earthquake swarm epicenter.

The nearest volcanic cone is Red Mountain, part of the lower Inyo crater complex associated with Mono Lake supervolcano.  Just to the North of Red Mountain is “Crater Mountain”, which was a previous earthquake swarm location.
