【摘要】 应用Jeanne L.Hardebeck和Peter M.Shearer编制的利用P波初动和振幅比计算地震震源机制解的程序,使用九江—瑞昌流动地震台观测的地震资料,初步计算了九江—瑞昌地震余震的震源机制;并对单独利用P波初动和利用初动及振幅比这两种计算方法进行了比较。综合最优计算结果,九江—瑞昌地震余震震源机制解为:走向174°,倾角62°,滑动角43°。更多还原

【Abstract】 The focal mechanism solution of the aftershocks of Jiujiang-Ruichang earthquake occurred on Nov.26,2005 is calculated by using the seismic wave data of the Jiujiang-Ruichang motion seismograph network based on the soft package of focal mechanism solution combining the first motion and S/P amplitude ratio,which is developed by professor Jeanne and Peter M.The results obtained are compared with those got only by P first motion.It shows that the focal mechanism of the aftershocks is strike 1740,dip angle 620 and slip angle 430 referenced to scientific expedition of the earthquake and the average result.更多还原
