The aim of this paper is to demonstrate the versatility of GIS (Geographic Information System) tools to map volcanic risk. The work was conducted within the Course of Thematic Mapping at University of Naples “Parthenope” and referred to one of the most significant volcanic area in Italy that is around the Vesuvius. Formula of UNESCO was used to map Risk: Map Algebra functions were applied to vector files concerning Hazard and Value, while Vulnerability, because of didactic simplification, was considered equal to a constant (value=1) for the whole geographic area. Georeferencing and vectorizing processes were carried out on the original raster map of Vesuvius Hazard while population data by ISTAT (the Italian National Institute of Statistics) were jointed to the shape file of the Campania Municipalities to build the Value layer. To consider more realistic distribution of people also CORINE Land Cover (CLC) layer was introduced taking into account the first level of its categories (Artificial, Agricultural, Natural areas).

Abstract

The aim of this paper is to demonstrate the versatility of GIS (Geographic Information System) tools to map volcanic risk. The work was conducted within the Course of Thematic Mapping at University of Naples “Parthenope” and referred to one of the most significant volcanic area in Italy that is around the Vesuvius. Formula of UNESCO was used to map Risk: Map Algebra functions were applied to vector files concerning Hazard and Value, while Vulnerability, because of didactic simplification, was considered equal to a constant (value=1) for the whole geographic area. Georeferencing and vectorizing processes were carried out on the original raster map of Vesuvius Hazard while population data by ISTAT (the Italian National Institute of Statistics) were jointed to the shape file of the Campania Municipalities to build the Value layer. To consider more realistic distribution of people also CORINE Land Cover (CLC) layer was introduced taking into account the first level of its categories (Artificial, Agricultural, Natural areas). Considering different sources of information (ISTAT data, CLC data, integration of ISTAT and CLC data) for Value layer definition, three different volcanic risk maps were obtained and compared.
