a Observed phase velocity dispersion curves (upper panel) and the real part of the cross-correlation spectrum (lower panel). Red and black circles in the upper panel represent the selected points of the dispersion curve and the average phase velocity dispersion curve for the region, respectively. b Location of the station pair for which dispersion data are displayed in panel a. c Phase-velocity–frequency plot showing the 23,647 selected dispersion curves for all the station pairs used
