The amplitude of the Fourier acceleration spectrum decays rapidly at high frequencies. This has been modeled by the parameter κr (Anderson and Hough, 1984). The site-specific component of κr, named κ0, describes the contribution of the first few km of the geological profile beneath a certain site. κ...
