a S-wave velocity profiles at KUMA in existing 3-D models of deep sedimentary layers. Black, blue and red lines indicate 1D S-wave velocity distributions extracted from J-SHIS (NIED, 2019), Koketsu et al. (2009) and Senna et al. (2018). b Comparison of observed Rayleigh-wave phase velocities (circles) and theoretical ones for S-wave models (lines) in a). Green, blue and red lines indicate 1D S-wave velocity distributions extracted from J-SHIS (NIED, 2019), Koketsu et al. (2009) and Senna et al. (2018). c 1-D S-wave velocity profile of shallow and deep sedimentary layers at KUMA as the “preferred velocity model” in the blind test in ESG6. The shallow part of the profile was constructed from results of S-wave velocity at borehole, while the deep part was imported from Senna et al. (2018)
