a Illustration of the site amplification factors defined in this study. ‘SA-S’ shows the site amplification factor evaluated from the S-wave portion of the strong-motion records. ‘SA-W’ shows the site amplification factor evaluated from the whole duration of strong-motion records including both S-wave portion and the basin-induce surface-wave contributions (that comes after the S-wave). Note that we call the portion including the S-wave and surface-wave (as well as S-coda) “the whole wave” in this paper. b The velocity waveforms observed at GNM003 and TKY015 on K-NET in Japan (the location of these site is shown in Panel (d) in this figure mentioned later). c The Fourier amplitude spectra of the waveforms observed at GNM003 and TKY015 on K-NET in Japan we mentioned above are shown in this panel. The black lines represent the waveforms observed at GNM003, the red ones represent the waveforms observed at TKY015. d The locations of GNM003 and TKY015 with the seismological bedrock-depth published by HERP (we explained it in detail later) are shown in this panel
