Qianguo—Qianan M_S4.8 Earthquake Sequence on March 31,2006 in Jilin Province
【摘要】 2006年3月31日,吉林省前郭县与乾安县之间发生4.8级地震,极震区有一定破坏,但无人员伤亡。本文对此次地震的余震监测及现场地震趋势跟踪分析进行了回顾,对3.7级余震前产生的微破裂机制进行了初步探讨,分析了震源破裂性质对余震序列强度的影响。
【Abstract】 An earthquake of M_S4.8 occurred between Qianguo county and Qian county in Jilin on March 31,2006,It caused some damages,but no casualties.In this paper,the earthquake monitoring and seismic tendency analysis have been reviewed,the micro failure mechanism prior to magnitude 3.7 aftershock are discussed.The influence of the characteristic of source mechanism to the strength of aftershock has been analysed also.
