Moment Tensors of Induced Microearthquakes in The Geysers Geothermal Reservoir From Broadband Seismic Recordings: Implications for Faulting Regime, Stress Tensor, and Fluid Pressure

Abstract: Full moment tensors of 1,421 microearthquakes in The Geysers geothermal field were calculated using waveform data from a field‐wide broadband network and the approach based on the principal component analysis. Spatial characteristics of faulting regime, stress tensor and the isotropic component (ISO) of moment tensors were investigated. The studied events form different clusters dominated by normal faults (NF) and strike‐slip (SS) faults, respectively. The SS‐dominated clusters are related to the SS stress sta… Show more

“…The recorded broadband, high‐density, and good azimuthal coverage continuous recordings resulted in one of the highest‐quality data sets for geothermally induced seismicity. Main noise components were found to be microseism (0.16 Hz) and anthropogenic noise (10–20 Hz; Yu et al, ).…”

“…Consequently, the local seismicity rate was significantly enhanced Dellinger et al, 2017;Majer & Peterson, 2007). In Yu et al (2018), the field-wide variations of faulting regime, stress tensor, and ISO component were investigated using the full MTs of 1,421 induced microearthquakes recorded by a broadband seismic network. R. Johnson, 2014b;Kwiatek et al, 2015;Martínez-Garzón et al, 2014.…”

“…In order to get robust results, ranges of five parameters; the DC, CLVD, and ISO percentages; and the orientations of P/T axes are calculated for a set of eight optimal MTs of each event (see Figure S2 in the supporting information). According to the statistical distributions (see Figures 5 and 10 in Yu et al, 2018), the total variations of the DC, CLVD, and ISO percentages and of the orientations of the P/T axes are determined at the 95% confidence levels.
