Based on 310 horizontal-component digital seismograms recorded at 14 seismic stations in Shanxi Digital Seismograph Network, the inelastic attenuation coefficient in Shanxi region is studied. By the methods of Atkinson and Moya, the site response of each station and several source parameters are obtained and the inversion results from both methods are compared and analyzed. The frequency-dependent inelastic attenuation coefficient Q is estimated as Q(f )=323.2 f 0.506. The site responses of 14 seismic stations do not show significant amplification, which is consistent with their basement on rock. We also found the dependence of comer frequency on seismic moment, seismic moment on stress drop, source radius on stress drop.
