The above in the blue squares, are today's earthquakes. You can see the swarm at the south end of the bean shaped lake. That's Salton Buttes volcano. This is from the USGS website.
Here is an example of today's earthquakes, in waveform. This is from the USGS.
Above is a map of the Eastern California Shear Zone, where there is a plate boundry, a good many faults and a rifting zone that will eventually separate California from the North American mainland. It has already done so further to the south, where Baja California is drifting away from mainland Mexico (North American Plate). Salton Buttes Volcano is at the southern tip of the pinkish area.
Here I am going nuts with my two favorite cameras, a Sony FX-1 and a Holga 120 format film still camera. This is at some vents and mud volcanos just east of the lava dome called Obsidian Butte, at the Salton Buttes volcano.
Here is a couple of vents at Salton Butte volcano, where brine is super heated by cooling magma about a mile and a half down, and brought to the surface, along with Co2 and Sulfur.
Here is a USGS example of the waveform on just one of the quakes on Feb. 11, 2012, at the volcano.
Here is a map of Southern California. The blue squares are earthquakes within 24 hours on Feb. 11, 2012, and the ones at the south end of the big bean shaped lake are the Salton Buttes events.There has been over a hundred small earthquakes at Salton Buttes volcano, on the Salton Sea, in the Southern California desert. They range from around 20 miles deep to under a mile deep. Much of the swarm is within a mile or two of the volcano, and then there is some more wide spread activity. One spring just outside of Indio has kicked into increased micro quakes as well, and usually does that when Salton Buttes has a swarm.
