Comparison of the estimated HSAF at the nearest (~ 1.2 km away) JMA station, EEB by GIT (Nakano et al., 2015), with the theoretical one-dimensional HSAFs by the inverted S-wave velocity profiles from EHVR and pEHVR, together with the HSAF by the preferred model. A geological map by Geological Survey of Japan (https://gbank.gsj.jp/seamless/) on the top shows the location of EEB relative to KUMA. The constant damping ratio of 1.1% is assumed for the pEHVR profile and preferred model, while the Vs-dependent damping (Table 3) is assumed for the EHVR profile
