Evaluation of the results of automatic earthquake location systems of Anhui network

  • 摘要: 目前,安徽台网正在运行的自动地震定位系统包括中国地震局自动地震速报系统(AU)、江苏省地震局自动定位系统、福建省地震局自动定位系统和安徽区域地震预警系统。以2015—2019年安徽及周边省份发生的地震实例为研究对象,将上述4套系统产出的结果分别与中国地震局统一正式目录对比,结果表明这4套系统产出的结果均在地震速报要求所允许的误差范围内,在安徽区域具备适用性和实用性,但在识别双震等方面存在缺陷。同时,这几套系统之间的对比结果表明,安徽区域预警系统产出结果参数的平均发震时刻差、平均震中位置差和平均震级差都相对较小。
