PreHmiuary analysis of the source parameters show that there is a high correlation between seismic moment Mo and local scale ML, which is lgtoMo = 0.92ML ＋ 10.24,correlation coefficient R is 0.86; Investigation of the relationship between stress drop and local scale ML indicates that the stress drop seems to be independent of ML.展开更多
