RETRACE-3D Central Italy Geological Model

Three-dimensional geological model of the area of the central Apennines affected by the 2016-2018 seismic sequence. The model consists of stratigraphic surfaces (top or basal unconformity of units, or sequences of units, with homogeneous behavior) and main faults of the area. The stratigraphic surfaces are, from the oldest to the most recent: the top of pre-Upper Triassic units, the top of the intra-Triassic units, the top of Calcare Massiccio, the top of the Marne a Fucoidi, the top of the Scaglia Variegata, and the unconformity placed at the base of the deposits of the Laga formation. Also included are all major faults in the area.
