Geophysical Data in the Reconstruction and Characterization of Plio-Quaternary Sediments

B013 GEOPHYSICAL DATA IN THE RECONSTRUCTION AND CHARACTERIZATION OF PLIO-QUATERNARY SEDIMENTS Abstract 1 This paper presents a case study on the capability of geophysical methods to reconstruct and characterize the surficial formations of a complex geological area. The area is located in a high seismic risk zone where there is contact between the Laziale-Abbruzzese and Umbro- Marchigiana seriers (central Italy) and where Plio-Quaternary sediments fill the tectonic valleys. The geophysical surveys collected on the outcropping Plio-Quaternary sediments include refraction P- and SV-waves high-resolution seismic reflection vertical electrical soundings (VES) and electrical tomography. The geophysical data were constrained with drillings and
