Abstract:Based on the Brune model (1970) and the seismic data of Wencheng-Taishun earthquake sequence recorded by the regional digital seismic network of Zhejiang,the paper calculated the corner frequency,zero frequency,source radius and seismic moment with genetic algorithm,and systematically analyzed the relationships between them.The paper studied 165 earthquakes with ML 2.0~4.4 from September to November in 2017.The result shows that the seismic moments are 101-1015 N·mand;rupture radius are 72~594 m;seismic stress drops range from 0.06 MPa to 3.12 MPa.No correlation wasfound between stress drop and hypocenter radius.log-linear and semi-log-linear relationships were found between seismic moment,corner frequency and body-wave magnitude.
