The Geysers represents a unique site for analysis of induced seismicity. This vapor-dominated geothermal field is located about 120 km north of San Francisco where the geothermal power production is performed for more than 50 years. Currently, The Geysers is the world’s largest geothermal field operated by Calpine and spanning an area of around 78km2 with the nominal capacity of 1517 MW. It is also an area of intensive induced seismic activity, with the largest event reaching magnitude 5.0. The seismicity is recorded with an extensive seismic monitoring networks operated by Lawrence Berkeley National Laboratory, and broadband regional network.
The availaibility of high quality data triggered our interest in understanding seismo-mechanical processes in this reservoir. This resulted in a number of publications, that I decided to gather in one place – The Geysers resesarch page.
I added a page dedicated to rpgen.m routine. RPGEN.m calculates P-wave, S-wave, SH-wave and SV-wave radiation pattern using shear-tensile source model. Original, it is a part of my paper “Assessment of P and S wave energy radiated from very small shear-tensile seismic events in a deep South African mine” published in Journal of Geophysical Research.
