摘要
利用新疆地震台网观测数据,对2024年1月23日乌什MS7.1地震序列进行分析,结果显示乌什地震序列的余震活动丰富,频度衰减较快.通过历史地震序列类比、序列参数(b值、p值、h值)、等待时间、震级差和能量比等参数的跟踪分析,判断此次乌什MS7.1地震序列为主震—余震型.从历史地震序列类型的早期定性判定到地震序列参数定量计算的跟踪判定乌什7.1级地震序列类型,对地震序列类型的跟踪判定有一定参考作用.
Abstract
Based on the observation data of Xinjiang Seismic Network,Wushi MS7.1 earthquake se-quence on January 23,2024 is analyzed.The results show that the aftershock activity of Wushi earth-quake sequence is rich and the frequency attenuation is fast.Based on the historical earthquake se-quence analogy,sequence parameters(b value,p value,h value),waiting time,magnitude differ-ence and energy ratio,Wushi MS7.1 earthquake sequence is judged as the main shock-aftershock type.From the early qualitative determination of historical earthquake sequence types to the tracking and determination of Wushi MS7.1 earthquake sequence types by quantitative calculation of earth-quake sequence parameters,it has certain reference function for the tracking and determination of earthquake sequence types.
