Nevada Earthquake Swarm

A recent swarm of earthquakes near Hawthorne, Nevada has quite a few scientists concerned. While most of the quakes have been small they are occurring in an area with no known fault line. This area is also just north of the Long Valley Caldera or otherwise known as a super volcano. As I am writing this it still seems unclear whether the quakes are from the movement of magma, possible fore shocks to a larger quake yet to come, or possibly just a regular swarm on a fault line which no one knew existed.
