| Abstract: | Based on the data of surface wave magnitudes from the catalog of China Seismograph Network from 1990 to 2016 and moment magnitudes data of the GCMT project, statistical relationship between surface wave magnitude of China Seismograph Network and moment magnitude is studied by weighted least squares method. We analyzed the residual error distributions of the relationships with the data used, and compared them with existing statistical relationships. The research results show that the statistical relationship obtained in this paper has good unbiasedness and can better reflect the corresponding relationship between surface wave magnitude of China Seismograph Network and moment magnitude. |
