统计整理小浪底库区近场地震，对地震位置进行精确定位，并计算较大地震的震源机制解，结合水库地震的活动特点，对地震活动和震源机制特征进行分析，认为小浪底库区地震活动具有水库地震特征，且同时受区域地质构造影响。
Through the arrangement of the seismic records of the near-field earthquakes in Xiaolangdi reservoir area, the earthquakes are relocated and the focal mechanism solutions of the larger earthquakes are calculated. Combining with the characteristics of reservoir earthquake activity, the characteristic of seismicity and focal mechanism are analyzed. It is considered that the seismic activity in Xiaolangdi reservoir area has the characteristics of reservoir earthquakes and also affected by regional structure.
