摘要:
利用广东省地震局地震监测技术及软件研发创新团队研发的两套地震自动编目处理系统,对2023年2月11日广东河源M4.3地震主震前1天以及后7天广东台网记录的连续波形数据进行了处理,并结合人工编目结果,对该时段内系统自动检测结果进行详细对比分析。结果表明:系统1自动检测的地震数量是人工目录的2.67倍,事件匹配率较高,而系统2自动检测的地震数量约为人工目录的二分之一,ML1.0级以下地震事件匹配率较低。两套系统自动检测结果均为地震事件,无误触发,自动检测事件真实率为100%。与人工目录结果对比,两套系统产出的发震时刻、震中位置、震源深度、Pg和Sg震相到时等均偏差较小,可靠度较高。综合来看,两套系统都具备地震自动编目的能力;其中,系统1处理大震后较密集余震的能力较强,可以产出完备性较好的地震目录。
Abstract:
Two sets of seismic automatic cataloguing processing systems developed by the earthquake monitoring technology and software R & D innovation team of Guangdong Earthquake Agency were used to process the continuous waveform data recorded by Guangdong seismic network one day before and seven days after the main earthquake of Heyuan M4.3 earthquake on February 11,2023. Combined with the manual cataloguing results,the automatic detection results of the system during this period were analyzed in detail. The results show that the number of earthquakes automatically detected by system 1 is 2.67 times that of the manual catalog,and the event matching rate is high,while the number of earthquakes automatically detected by system 2 is about half that of the manual catalog,and the matching rate of earthquake events with ML≤1.0 is low. The automatic detection results of the two systems are all seismic events,the real rate of automatic detection events is 100%. The deviation between the automatic catalog and the manual catalog produced by the two systems is small in the earthquake origin time,epicenter location,the focal depth,the arrival time of Pg and Sg phase,and the reliability is high. On the whole,the two systems have the ability of seismic automatic cataloging. In contrast,system 1 has a stronger ability to handle dense aftershocks after a large earthquake and can produce a relatively complete earthquake catalog.
