Originally proposed by Nogoshi and Igarashi (1970, 1971), the ambient vibration H/V spectral ratio (HVSR) method consists of estimating the ratio between the Fourier amplitude spectra of the horizontal (H) to vertical (V) components of ambient noise vibrations recorded at a single station. This method, widespread by Nakamura (1989, 2000), is now widely used for evaluation of site effects and in seismic micro‐zoning studies (e.g., Guéguen et al., 2000; Alfaro et al., 2001; Duval et al., 2001; Guillier et al., 2004; Panou et al., 2005; Chatelain...
