Fig. 9

DFA-SW (red) and DSS-SW (blue) H/Vs of cap-layered media at six KiK-net strong-motion stations. The underground velocity structures from surface to cap layer are used to evaluate DFA-SW and DSS-SW H/Vs. Smoothing (Konno and Ohmachi 1998) is applied on DSS-SW H/Vs, but not DFA-SW H/V which is already smoothed
