Fig. 3

Comparison of local amplitude corrections \({s}_{i}\) at different frequency bands. Circle colors represent the logarithm of observed amplitudes without corrections \({E}_{i}\) (top row) and the corrected ones \({\widetilde{E}}_{i}\) (bottom row). Background colors show the theoretical amplitudes (theoretical attenuation) assuming isotropic radiation of surface waves from Anak Krakatau
