水库地震震源深度校核方法研究与应用

采用人工方法对溪洛渡库首区流动台和距离地震震中最近的4~5个台站的原始数据进行重新分析，将获得的地震震源深度与台网目录的震源深度进行对比分析，发现二者存在明显偏差。流动台和距离震中最近的台站确定的震源深度能更合理地解释地震的成因及水库诱发地震的机理，可为其他水电工程研究水库诱发地震成因时运用地震观测数据确定较为可信的地震震源深度方法提供参考。

Research and Application of Reservoir Induced Earthquakes Focal Depth Checking Method

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.
