利用小震分布和区域应力场确定磁县1830年7.5级强震断层面参数

摘要

对邯郸地震台网1984-2008年记录的磁县小地震,作双差定位,然后根据定位结果,对磁县历史强震断层参数作反演计算,求解磁县历史强震断层走向、倾角等特征参数,根据当地应力场来估算磁县历史强震断层的滑动角.%In this article, using the seismic data recorded by Handan seismic station net from 1984 to 2008, the Cixian small earthquakes are located with the double difference location method. Then, according to the result of localization, the macroseismic fault parameter of the Cixain history earthquakes is inversed. The macroseismic characteristic parameters of Cixian history earthquakes, such as the strike, inclination of fault, are extracted. The angle of fault slip is also estimated according to the local stress field.
