Session 3.2 GNGTS 2024 substrate depths identfed in the nearby boreholes. This empirical relatonship is valid for the shallow subsurface within the depth range used for the regression analysis (say, from -60 to -230 m), which allows the conversion from the frequency to the depth domain of the HVSR curves. These results have several practcal applicatons: frstly, they help identfying areas that are likely to experience greater ground moton amplifcaton during an earthquake; secondly, they enable the development of empirical formulas for estmatng the depth of the seismic bedrock based on HVSR outcomes (Martelli, 2021) with high accuracy; and thirdly, they highlight signifcant stratgraphic and structural diferences between the Mirandola and Casaglia areas.
