Fig. 14

Plots of H-to-V spectral ratios of surface recordings during weak-motions (gray lines) and those during the mainshock (red lines) at K-NET sites. See Fig. 3 for site location. The plots are arranged in order of decreasing horizontal vector PGAs in panels ap, respectively. Solid black line denotes mean spectral ratios for weak-motions, and dashed gray lines denote one standard deviation. The horizontal vector PGA in units of cm/s2, horizontal vector PGV in units of cm/s, Vs30 in units of m/s, DNL values, and fault-to-site distance (R) in units of km are also included for each site
