Abstract
The expansion of geothermal development into the SE part of The Geysers field has been accompanied by the introduction of induced seismicity. Over 1000 microearthquake events are now recorded annually. One major cause appears to be injection, which results in the reservoir rock being rapidly cooled. A recent doubling in injection has increased by about 50% the number of M.2.4 events being recorded, with no increase observed in M]2.5 events.
