USGS Earthquake Swarms Information

There appears to be the beginnings of a small swarm of earthquakes in the Brawley Seismic Zone, this time in the town of Brawley, California. The USGS has a great website on swarms and why they occur.

Site Expansion Coming Soon – Imperial Valley Geology

As an extension of my coverage of the geology here in Southern California, I intend to add a page on the geology in the Imperial Valley region. Subjects such as the Salton Sea, mud pots, Lake Cahuilla, the Colorado River Delta, and more as time permits. There is a lot to cover and more to the region than normally meets the eye.
