| Abstract: | 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. |
