Several integrated geophysical surveys are performed by OGS in different sites located in the Friuli Venezia-Giulia region (North-East of Italy) to characterise the near surface subsoil for seismological applications. For this purpose we used seismic geoelectric and ground penetrating radar (GPR) methods. The first meters are described in details by GPR measurements the fifty meters by electric data and the layers until the basement are illuminated by seismic surveys. The results obtained at different resolution are in very good agreement and the direct measurements (downhole and cross-hole)
