Comparison of peak frequencies from strong-motions (mainshock) and weak-motions S-to-B spectral ratios for horizontal components at the KiK-net sites (circles) and H-to-V spectral ratios at the K-NET sites (triangles). The data points are color-coded by horizontal vector PGAs at the surface in a, Vs30 values in b, and DNL values based on the S-to-B spectral ratios in c, respectively. The sites where Vs30 values were not estimated are denoted by diamonds (see Table 3 for the Vs10 values at the sites). Some data points that might be of interest to readers are provided with their site codes near the data points
