396 GNGTS 2018 S essione 2.2 any literature data; 4) two seismo-stratigraphic cross sections, that show a great match with the 2D HVSR contours obtained after the interpolation of the HVSR results. Further acquisition of 2D arrays will be necessary to better constrain the shear-wave velocity profile in the Southern sector of the basin, as well an accurate and reasoned integration of all the geological, structural and geophysical data gathers. Such a process would be useful in order to create a geological model of the entire basin aiming to clearly display the depth variations of the deposits/bedrock interface, that may bring onto a better the understanding of a possible link with the seismic response of the basin.
