| Abstract: | Based on digital seismograms recorded at 17 stations of XinJiang,the inelastic attenuation coefficient of seismic waves is calculated using genetic algorithm and the method proposed by Atkinson and Mereu.Then,the station site response and source parameters are investigated with the approach of Moya and Jorge.The frequency-dependent S wave Q in Xinjiang region is estimated as Q(f)=460.7f0.515.Site responses of 17 stations show different amplifications.In semi-logrithmic coordinate magnitudes are positively c... |
