    Description: The statistical analysis of stream orientations is an helpful tool in the active tectonic studies because the rivers network is an important geomorphologic feature useful to derive the deformation due to active faults. The drainage network automatically derived from DTM’s is not generally usable for this type of analysis because the automatic routines generate the stream network following the four direction orthogonal to the cell. In this paper we present a semiautomatic methodology to extract the drainage network from high resolution DTM data (5x5 pixel m) the most possible consistent with the real water-drainage pattern, in order to make accurate statistic azimuthal analyses of stream orientations. The methodology have been tested on the active tectonic area of the Tammaro basin (Campania and Molise Regions), epicentral zone of the 1688 strong earthquake (MW=6.7). The results obtained by the application of the proposed methodology show a good agreement with the drainage pattern map derived from photo-interpretation (Regional Technical Cartography).

    Description: A high-resolution Digital Terrain Model (DTM) of Campi Flegrei caldera, obtained from an airborne LiDAR mission, has been analyzed in order to produce a 1:20,000-scale morphometric map of this volcanic area. The map consists of different thematic layers, which include: profile curvature, terrain ruggedness index, elevation range, as well as an upto- date structural map and building distribution in the densely populated area. Results evidence that most of the relief is related to the occurrence of tuff-cones, tuff-ring, and the outer flanks of the caldera. Higher values of elevation characterize the upper portions of cones, while higher terrain ruggedness index values concentrate on the inner flanks of cones and in areas affected by gravity and erosional processes. The map also evidences the topographic expression of crater rims and of the major morphological scarps, which reflect ancient and uplifted shorelines and present-day cliffs.
