Its proximity to an enhanced geothermal system site, where high-pressure hydraulic injection had been performed during the previous 2 years, raises the possibility that this earthquake was anthropogenic. We have combined seismological and geodetic analyses to characterize the mainshock and its largest aftershocks, constrain the geometry of this seismic sequence, and shed light on its causal factors. According to our analysis, it seems plausible that the occurrence of this earthquake was influenced by the aforementioned industrial activities. Finally, we found that the earthquake transferred static stress to larger nearby faults, potentially increasing the seismic hazard in the area. date: 2018 publication: Science volume: 360 number: 6392 publisher: American Association for the Advancement of Science pagerange: 1003-1006 id_number: doi:10.1126/science.aat2010 issn: 0036-8075 official_url: http://doi.org/10.1126/science.aat2010 access_IS-EPOS: unlimited owner: Publisher acknowledgments2: SHEER_project citation: Grigoli, Francesco and Cesca, Simone and Rinaldi, Antonio Pio and Manconi, A. and Lopez-Comino, Jose Angel and Clinton, J.
