- W2392291815 abstract "Based on 155 horizontal-component digital seismograms of 23 earthquakes recorded by 7 stationsof Urumqi Digital Tele-seismic Network and the Kuerle regional station, which have been formally runsince 2001, the inelastic attenuation, geometric spreading pattern of the central and eastern Tianshan re-gion, as well as the site response of each station were investigated. Firstly, the signals were corrected forinstrumental responses. Then, we adopted a lag-window spectral technique to obtain a stable Fourier spec-trum of the signals and noises. By subtracting the noise spectrum from the signal spectrum, the noise-cor-rected Fourier amplitude of displacement was obtained. Assuming a hinged tri-linear geometrical spreadingmodel directly following Atkinson, we corrected the spectra, and furthermore used the joint-inversion todetermine the inelastic attenuation co-efficiency C(f) and Q(f) by performing regression iteratively. Final-ly, the tri-linear geometrical spreading pattern were obtained. When hypocenter distance, R, is less than68 km, which corresponds to attenuation of the direct-wave, the wave attenuated with R~(-1). When R is be-tween 68 and 113 km, which corresponds to a transition zone as the direct-wave is joined by post-criticalreflections from mid-crustal interfaces and Moho discontinuity, the energy of S almost does not attenuate.When R is greater than 113 km, which corresponds to attenuation of multiply reflected and refracted Swaves, the wave attenuated with R~(-0.5). The frequency-dependent Q in this region is estimated as Q(f)=344·f~(0.55), which is consistent with the seismic activity in this area, characterized by frequently small tomoderate earthquakes but lack of large earthquakes. This study pays the way for the future seismologicalresearches in this area, including recovering the real source spectrum, modeling the ground motion,etc." @default.
