Geomorphological map of the 1944 Vesuvius lava flow (Italy).

The map of the 1944 lava flow shows the geomorphological characteristics of a sector of the Vesuvius volcano (Italy) covered by the products emitted during the last effusive phase. The map has been produced based on the analysis and interpretation of (a) thematic maps (slope, aspect, relative relief) derived from a high resolution (0.33 m pixel) Digital Terrain Model (DTM) obtained by a Airborne Laser Scanning (ASL) survey, and (b) a 1 m pixel digital colour orthophoto. Different flow structures and morphologies have been recognized. The analytical approach proposed here can be used to characterize the smaller scale topographic/geomorphological features of volcanoes and gives constraints on the mechanism of emplacement and modelling strategies of lava flows.
