Although increased seismicity commonly accompanies geothermal production, induced earthquake rate cannot currently be forecast on the basis of fluid injection volumes or any other operational parameters. We show that at the Salton Sea Geothermal Field, the total volume of fluid extracted or injected tracks the long-term evolution of seismicity. After correcting for the aftershock rate, the net fluid volume (extracted-injected) provides the best correlation with seismicity in recent years. We model the background earthquake rate with a linear combination of injection and net production rates that allows us to track the secular development of the field as the number of earthquakes per fluid volume injected decreases over time. date: 2013-07-11 date_type: published publication: Science volume: 341 number: 6145 publisher: American Association for the Advancement of Science pagerange: 543-546 id_number: doi:10.1126/science.1239213 refereed: TRUE issn: 0036-8075 official_url: http://dx.doi.org/10.1126/science.1239213 access_IS-EPOS: limited owner: Publisher citation: Brodsky, Emily E. and Lajoie, L.
