The middle diagram is the global map of the Rayleigh-wave phase-velocity at a period of 100 s (Trampert and Woodhouse, 2001). Triangles denote the used stations in this study. Also included are travel-times (open circles) and the Fourier spectrum from several stations. Closed circles are the travel-times of the 100-s Rayleigh wave calculated from the global map of 100-s Rayleigh-wave phase-velocity. Numbers within the diagram of the Fourier spectrum denote the spectral-node period.
