Geothermal activity near Clearlake, California
Abstract
Geothermal activity in the region of high heat flow near the city of Clearlake includes hot springs, fumeroles, vents, and areas of hydrothermal alteration. Onshore, the location is controlled by Quaternary longitudinal NNW-trending faults of the San Andreas systems, and the transverse Burns Valley fault. Offshore, an additional control is arcuate graben-forming faults. The city is bracketed by three hydrothermal 'hot spots,' which are Sulphur Bank hot spring, resurgences in Burns Valley, and the Oak Cove hot spot. All three are associated with sharp 'spikes' in the isotherms and locally enhanced heat flow.
