Schematic structural map where Highly Deformed Apennine Ridge (HDAR) and Nearly-Undeformed Adriatic Foreland (NUAF) are shown with the location map of the boreholes analyzed in this work. Green, Red and Yellow dots are for boreholes where, respectively, sonic logs, check shots or both were available.

Map was generated by using Inkscape (1.0.2, https://www.inkscape.org) graphic editor. Major fault traces are those reported by81, while wells have been positioned by using Matlab (R2020b, https://www.mathworks.com) following Latitude and Longitude information35 for each well.
