Hundreds of Quakes Continue at Salton Buttes Volcano in Southern California

There have been today about 80 or so small to moderate earthquakes at the Salton Buttes Volcano at the Salton Sea in Southern California. This is an earthquake swarm because the events are highly localized. What is very interesting about this, that that most of the events are on near surface, which makes me wonder if this has got something to do with some drilling in the area, or the release of steam. There are some events 8 miles down, which is within the magma chamber.

Indeed Salton Buttes has a hot magma chamber under it, and like I say all the time, this chamber is extensive and stretches a good 20 miles.

Here is a USGS link to the list of earthquakes as of this writing: http://earthquake.usgs.gov/earthquakes/recenteqscanv/FaultMaps/115-33_eqs.html
