Examples of HVSR ratios computed for two stations: a SS5 of KUM-SS1 array and b LL6 of KUM-LL array. Each plot shows results from 39 individual time windows (grey lines) together with their average values (solid lines). In all plots, black line corresponds to EW component and red line to NS component. We marked with 1st, 2nd and 3rd the three main significant peaks observed in the spectral ratios. Plot c shows the average HVSR ratios calculated for all stations deployed around the KUMA station (65 in total). The theoretical 1D transfer function applying the Kennett’s reflectivity coefficient method to the VS model of Fig. 6 is superimposed with the blue thick line
