Comparison of Rayleigh-wave phase-velocity dispersion curves of the selected station pairs for different paths: a five BB station pairs with approximate interstation distances of 50 km transect different portions of the study region; and b six BB and SP station pairs with approximate interstation distances of 10 km transect different portions of Aso caldera. The solid black line with circle markers represents the average Rayleigh-wave phase-velocity dispersion curve displayed in Fig. 7
