Comparison of vertical-component velocity seismograms obtained by the frequency–wavenumber integral method of Saikia (1994) (black curve) and OpenSWPC (red curve) in the frequency range of 0.01–0.5 Hz under the laterally homogeneous structure of Kubo et al. (2002). The amplitude at each distance is normalized by the maximum amplitude of the trace obtained by the frequency–wavenumber integral method. Note that the two traces at the same distance are slightly shifted vertically so that they do not overlap
