Surface wave propagation – semblance analysis. Left upper panel: The synthetics band passed for the semblance analysis (0.2–0.38 Hz) for model Vsmin500 at a particular station of each of the FD arrays used for semblance analysis. The right panel shows the time series of the slowness vectors (in black) with detected slowness in m/s (from semblance technique). The corresponding polarization azimuths are represented by the red sticks. See also Fig. 4
