国家地震烈度速报江苏子系统震源机制解产出分析
Analysis of Focal Mechanism Solutions Output of the Jiangsu Subsystem in the National Earthquake Intensity Rapid Reporting System
摘要
Abstract
The Jiangsu sub-project of the National Earthquake Intensity Quick Reporting and Early Warning System integrates the TDMT_INV method for rapid reporting of source mechanism parame-ters,enabling direct reading of seismic phases for inversion calculation and production of source mech-anism solutions.To verify the accuracy of this method,this paper selected two earthquakes of magni-tudes 3 or above:the 3.0-magnitude earthquake in Dongtai,Jiangsu on January 17,2024,and the 3.8-magnitude earthquake in Ganyu Sea,Jiangsu on December 7,2023.The TDMT_INV,CAP,and FOCMEC methods were utilized to calculate their source mechanism solutions and to analyze the dif-ferences in results obtained from the three methods.The Donghai 3.0-magnitude earthquake,located within the Jiangsu early warning network,produced relatively stable source mechanism solutions across all three methods.Despite the Ganyu Sea 3.8-magnitude earthquake occurring outside the Jiang-su early warning network,the TDMT_INV method still produced relatively stable source mechanism solutions.关键词
