Dataset: Stress drops and its probability density functions of events from Prati-9 and Prati-29 seismicity cluster at The Geysers geothermal field, California
Stress drops and its probability density functions calculated for 328 events from Prati-9 and Prati-29 seismicity cluster at The Geysers geothermal field with mesh spectral ratio technique. The dataset was produced by Staszek et al. (2017) and was further analysed by Staszek et al. (2021) and Staszek et al. (2025).
