In this paper, the preliminary results of a research aimed to reconstruct the morphotectonic framework of the Tammaro River basin are presented. The use of dedicated geographic information systems (GIS) enabled an efficient managing and processing of heterogeneous datasets, produced using GIS-aided classical techniques of geological and geomorphological analysis of the relief. On these data, advanced statistical processing procedures were carried out. The Tammaro R. basin corresponds to a sector of the Southern Apennines experiencing a general SW-NE extension, with several evidence of recent seismicity, and looks very similar to other intermontane basins hosted along the axis of the Apennines. The basin is dominated by NE-SW striking faults that seem to be the key structures for the morphotectonic evolution of the area. NW-SE, N-S and E-W azimuthal sets of faults are also well represented and seem to have played a minor role. The existence of these faults is confirmed by clear geomorphological evidence, such as fluvial elbows, subsequent reaches of streams, straight slopes shaped as triangular or trapezoidal facets, fault scarps and displacements of five orders of palaeosurfaces.
