| 摘 要： | Introduction Seismic recording is the information recorded by seismograph when earthquake occurs, which is a kind of comprehensive information, including the characteristics of earthquake focus, propagation path of seismic wave and site response, etc. Therefore, we must try to distinguish source effect, propagation path and site response in the seismic recordings in order to obtain accu-rate parameters. The method of Atkinson has better solved the problem (Atkinson, Mereu, 1992), which is bas…

| Abstract: | Based on 310 horizontal-component digital seismograms recorded at 14 seismic stations in Shanxi Digital Seis-mograph 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 corner frequency on seismic moment, seismic moment on stress drop, source radius on stress drop. |
