Site amplification factors with whole wave (SA-W) evaluated from Fourier spectra which were classified by the predominant frequency at TKY007 in Japan in relation to the source locations. The black line indicates SA-S, and the red line indicates SA-W. a Map of the epicenters of the events where strong-motion records were observed at TKY007. The star symbols represent the event with a predominant frequency around 0.125 Hz (8 s in period) in the SA-W and the cross symbols represent the other events. b Distributions of the source parameters with their focal depths and JMA magnitudes. c Site amplification terms with S-wave and whole waves calculated by all observed records used in this study at TKY007. d Site amplification terms with S-wave (SA-S) and whole wave (SA-W) calculated for events with a predominant frequency at 0.125 Hz at TKY007, shown by starts in a. e Site amplifications with S-wave (SA-S) and whole wave (SA-W) calculated for events without a predominant frequency at 0.125 Hz at TKY007, shown by x marks in a
