Figure 7

Sedimentary structure in the area of the red solid square in Figure 1 . (a) Distribution of the 190 stations that were used for the estimation of the spatial variations of V 0 and α, (b) bedrock depth, (c) spatial variations of V 0 and α, and (d) examples of local S-wave structures at three sites. Open circles, squares, bold triangles, and bold diamonds are data points from VSP measurements (Yamamizu 1996, 2004; Yoshimoto and Takemura 2014a), the waveform analysis using the initial model (Figure 3), the JIVSM (Koketsu et al. 2008, 2009), and microtremor surveys (Matsuoka and Shiraishi 2002; Yamanaka et al. 2005; Senna et al. 2013), respectively.
