Cartografia speditiva delle tracce di valanga sui versanti meridionali delle Malacoste (catena del Gran Sasso, Abruzzo) ai fini di una migliore conoscenza del rischio ambientale

Fast mapping of the avalanche tracks on the Southern side of Malacoste (Gran Sasso Range, Abruzzi) for a better knowledge of environmental risk. – This note shows the results of a research, conducted in the Gran Sasso area, on the risk of avalanches and related territorial consequences. The study is based on a geological and geographic approach and uses techniques of fast mapping and field research. It was possible to identify the traces of 85 events that occurred between 2007 and 2017, which are many more than those officially registered. This made it possible to specify, at least for the type of wet-snow avalanches, the areas most subject to the phenomenon and highlighted the environmental risks and possible dangers for the visitors in the area. Therefore, it provided useful indications for a more prudent management of risk and better territorial planning.
