Abstract

In this study, the seismic events (>ML 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 fc, zero frequency limit Ω0, seismic moment M0, stress drop ∆σ, and apparent stress σapp. 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.
