    Abstract: The use of Gis in avalanche assessment is widely adopted, it performs analysis which help to make decisions in land management. The aim of this work was to apply different tools, provided by a GIS software, for the study and management of the avalanche risk in the Region of Valle d'Aosta (north-west of Italy) and in the ski resort "Piancavallo" in Friuli Venezia Giulia Region (north-east of Italy). As a goal and also a starting point for further processes, a geodatabase of the Regional Avalanche Inventory was created and divided into several raster datasets, feature datasets and feature classes related to avalanches. Then, within the Interreg project Italy-Switzerland "STRADA”, still in progress, strategies for the avalanche hazard mitigation were found, focusing in particular on roads crossed by avalanche paths. That was reached by assessing a procedure, obtained interpolating (geoprocessing) features related to avalanches, roads and buildings, which provides a useful tool to identify the sites that might be suitable for artificial avalanche triggering. This process could help in avoiding the preventive closure of roads, and such application can be the starting point for more detailed analysis, necessary to provide decisionmaking to local governments in emergency management. Finally, a methodology, processed from digital terrain models, allowed the identification of the potential release areas in the Piancavallo ski-resort realized through various steps in geoprocessing environment, or through file .aml of Arc Info Workstation.
