Rayleigh waves phase velocity from synthetic vertical velocity in Fig. 14 for model C. Synthetic waveforms are analyzed in ranges of 5 m from the source: 5–10 m, 8–13 m, 11–16 m, 14–19 m, 17–22 m and 20–25 m. Plotted points represent the observed phase velocity recorded at each source distance. The solid line represents the theoretical dispersion curve of the fundamental mode Rayleigh wave for the model. The two dotted lines indicate the maximum and minimum wavelengths resolved by the linear array, respectively. The frequency bands of capable wavelength are focused
