实时智能地震处理系统在2013年福建仙游ML5.0地震序列中的应用研究
Application of Real-time Intelligent Seismic Processor in Xianyou ML5.0 Earthquake Sequence in Fujian Province in 2013
摘要
Abstract
In this paper,the Real-time Intelligent Seismic Processor(RISP),an artificial intelligent(AI)based processing system was applied to the Xianyou earthquake sequence in Fujian to process the continuous waveform data of the Fujian network from August to December 2013.The automatic results were compared with the manual seismic catalogs to evaluate the processing capacities of the RISP system.During the period,a total of 615 earthquakes were processed by the system,fewer than the number of manual results.Among the automatic results,462 events were matched with manual results,the matching rate reached 96.4%for events with ML≥1.0;282 events were missed and 94.7%of them with ML<1.0;162 more events were detected,which were all belonged to Xianyou earthquake sequence.The statistical results of the source parameters showed that the proportion of data with the earthquake origin time deviation less than 1.0 s was 99.13%;the proportion of data with epicenter position deviation less than 5 km was 98.69%;the proportion of data with a depth deviation of the focal point less than 5 km was 91.5%;the proportion of data with a magnitude deviation less than 0.5 was 89.54%.This result shows that under the existing observation conditions,the RISP system can quickly produce catalogs of earthquake sequences with ML≥1.0,and the completeness of the earthquake catalogue is high.The accuracy of seismic parameters produced by RISP system is equivalent to that of manual processing,which can be applied to emergency response of large earthquake and post-earthquake trend determination关键词
