摘　　要：2019年12月9日12时29分,北京市、河北省、天津市地震台网同时记录到河北三河——北京平谷交界发生非天然地震,震级MS1.0。由于同样的经纬度在不同版本地图更新情况下不同、数据的不完全性及人工测量存在一定误差等特殊原因,地震类型识别困难,因此用地震波型来识别该地区发生的地震事件类别这一手段具有十分重要的意义。基于北京市台网地震台站的实时波形记录记录数据,使用了LOCSAT定位法对该事件进行了识别与分析,研究结果表明,此次地震事件为三河地区的一次爆破地震。An unnatural MS1.0 earthquake occurred at the junction of Sanhe of Hebei and Pinggu of Beijing at 12:29 on Dec.9,2019,which was recorded by the seismic networks of Beijing,Hebei and Tianjin simultaneously.Due to such special factors as differences of same longitude and latitude in different versions of map updating,incomplete data,and errors in manual measurement,it is difficult to identify the earthquake types.Therefore,it is of great significance to apply wave types in identifying the types of seismic incidents in the study region.Based on the real-time waveform recording data in Beijing Seismic Network,we used the LOCSAT positioning method to identify and analyze this incident.And the results show that this earthquake is a blasting earthquake in Sanhe area.
