摘要
本文介绍了一种横向不均匀介质中地震参数的修定方法。该方法以渤海及其邻区地壳、上地幔结构的最新成果为基础构造速度模型,集中起可利用的渤海周边地区的山东、河北,北京和辽宁等台网的资料,统一修定了近年来渤海及其邻区598个地震的震源参数。所有地震都给出了震源深度并且讨论了地震定位的精度。文中给出了近年来渤海内M_L≥4.0级的地震震源参数修定结果,讨论了该区震源深度分布的特征。
A method of revising earthquake parameters in inhomogeneous medium has been proposed. Based on the data recorded by Shandong, Hebei, Beijing, and Liaoning station nets around Bohai sea,we applied the method to revise 598 earthquakes occurring in Bohai sea and its adjacent areas and obtained their parameters including focal depths by using the latest results about the crust and mantle structure of the area to form the velocity model. The accuracy of earthquake location and the distribution of focal depths have been discussed. The results which occurred in Bohai sea in recent years and satisfied M1 ≥4. 0 have been presented.
