Abstract: In this study, the seismic events (> M L 2.0 earthquake motion records recorded by China earthquake net stations) in Western China are calculated and the source parameters of several hundreds of seismic events are obtained, such as corner frequency f c , zero frequency limit Ω 0 , seismic moment M 0 , stress drop ∆ σ , and apparent stress σ app . The 95% confidence interval of each parameter of each earthquake is obtained. The sample area is about 100 km × 400 km. Then, the calculation results are compared with statistical results, which shows that the correctness and feasibility of the fitting analysis are feasible and correct. Finally, several conclusions and prospects are presented and discussed.
