We present an in-depth characterization of the shallow subsurface in a coastal area of the northern Adriatic. In this research, we integrated the results from the processing of active seismic data (P-, SH-, SV- wavefields, and surface waves) with those obtained from electrical resistivity tomography. Seismic data analysis provided stacked sections as well as velocity profiles from first-break tomography. Furthermore, surface-wave analysis was performed to obtain a S-wave velocity model. The results show a highly heterogeneous subsurface, due to changes in water saturation, as well as in the properties of the sediments. This is consistent with the geology of the area, characterized by sand deposits and clay sediments.

Abstract

We present an in-depth characterization of the shallow subsurface in a coastal area of the northern Adriatic. In this research, we integrated the results from the processing of active seismic data (P-, SH-, SV- wavefields, and surface waves) with those obtained from electrical resistivity tomography. Seismic data analysis provided stacked sections as well as velocity profiles from first-break tomography. Furthermore, surface-wave analysis was performed to obtain a S-wave velocity model. The results show a highly heterogeneous subsurface, due to changes in water saturation, as well as in the properties of the sediments. This is consistent with the geology of the area, characterized by sand deposits and clay sediments.
