Abstract:In this study, we reanalyze the wave records from temporary seismic monitoring stations and the 4 to 5 permanent stations closest to the epicenter in the head region of Xiluodu Reservoir. The focal depth of the relocated earthquakes is compared with the network catalogue, and there is a clear deviation. The focal depth determined by the temporary stations and the permanent stations closest to the epicenter can explain the cause of the earthquake and the mechanism of the reservoir induced earthquake. It can provide references for other hydropower projects in the study of reservoir induced seismicity, and how to use seismic observation data to determine more credible seismic focal depth.
