dc.description.abstract	Site characterization surveying is one of the key efforts for the understanding of local amplification effects in earthquake engineering. In this perspective, geophysical measurements for the estimation of the physical properties of the subsurface at instrumented sites are particularly important. For instance, the comparison between simulated site amplification based on the retrieved Vs profile and empirical local response observed at the station allows assessing whether the site is characterized by a purely 1D response or additional 2D-3D effects are present. We present a case study involving a site characterization measurement at a station of the Swiss strong-motion network. The survey includes active seismic data acquisition along two geophone lines, of 15 and 115 m length, for the imaging of the near-surface and deeper layers, respectively. The acquired data were interpreted in terms of P-wave refraction and Rayleigh-wave multi-modal propagation analysis. The reconstructed Vs-Vp profiles achieve a high level of accuracy over a wide depth range and allow modelling the SH-transfer function of the local soil column; the latter is in excellent agreement with the local amplification function estimated by means of empirical spectral modelling of the station’s recordings. The agreement confirms a purely 1D site response for the surveyed station.	de_CH
