f S-Wave velocities and shallow layering in a Campi Flegrei site (Naples) through R-wave spectral analysis

The Spectral Analysis of Surface Waves (SASW) method is a nondistructive seismic testing aimed to determine shear wave velocities and layering from surface measurements of artificially generated Rayleigh waves (R-Waves). The SASW method has been mostly employed in the evaluation of the elastic properties of pavements (Heysey et al. 1982; Nazarian and Stokoe, 1983) and was also experimented for determining shear wave velocity profiles in a liquefaction susceptible site.
