Recorded by the 31‐station short‐period Berkeley‐Geysers seismic network, the events have duration magnitudes 140 Hz) estimates are obtained compared with the southwest. In contrast, geothermal production rate variations, analyzed for a tight cluster in the northwest, do not influence the QC(f) estimates. Moreover, we compare the QC(f) results with previous estimates of direct S‐wave quality factors (⁠QD⁠). A match for QC results at 7 Hz center frequency with QD estimates is observed. However, QC estimates show lower scattering and thus a higher stability. You do not have access to this content, please speak to your institutional administrator if you feel you should have access.
