本文介绍一种利用近震P、S波到时,在任意垂直非均匀介质中利用广义反演理论确定地震事件空间位置的概率分布的方法及计算程序。做为一个例子,给出了用这个方法对滦县近场地震观测资料的数值计算结果,并与程序HYPO81所得的结果作了比较。
This paper presents a method and calculation program for using the generalized inversion theory to determine the probability distribution of seismic event location in any vertical inhomogeneous media using near-P and S-wave arrival. As an example, the numerical results of the near-field seismic observation data of Luanxian by this method are given and compared with the results obtained from the program HYPO81.
