Fig. 8

Phase velocities of Rayleigh waves at HKD126. The open circles denote the observed phase velocities using the SPAC method and the open squares denote those obtained using the MASW method. The solid lines denote the theoretical phase velocities for the AIST, J-SHIS V2 and Hatayama et al. (2007) models. The right panel shows the details of the low velocity part
