- Abstract:
- Yingjiang MS5.9 earthquake On August 21,2008 occurred in Yunnan.Using waveforms of the ML≥2.5 earthquakes recorded by Yunnan Regional Digital Network.By removing propagation,site and instrument effects from the displacement spectra of the S-wave recordings,we obtain the source parameters of 196 ML≥2.5 earthquakes based on the Brune disc model and Genetic algorithm,namely,the seismic moment M0,stress drop Δσ and rupture radius r.The results show that there is a good linear relation between M0(1012～1016 N·m)and local magnitude ML,M0 and rupture radius r.Δσ seems dependent on ML; fc increases with M0 decreasing according to the lgfc-M0 relation.
