- Abstract:
-
According to 437 horizontal-component seismograms recorded at 21 stations of Gansu Digital Seismic Network,we used Genetic Algorithm and Atkinsons method to study the inelastic attenuation value Q of the northeastern margin of Qinghai-Tibet plateau and the site response of each station based on the trilinear geometrical spreading model.The results indicate that the frequency-dependent of inelastic attenuation value Q in the studied area is estimated as:Q(f)=564.7f 0.3.The site response shows significant amplification at every station except for the Wudu,Hezuo,Huangyuan,Dingxi,Diebu stations.
