Abstract
Geographic Information Systems (GIS) have become an essential tool in studies dealing with natural hazard prevention. The use of GIS covers all the phases of analysis, from the acquirement, integration and treatment of information to the conversion of such information into specific knowledge about hazards affecting a territory and its vulnerability to natural disasters. Today, GIS are essential tools in the development of thematic maps that represent the hazards and vulnerability of a specifi c territory. A proper risk assessment depends on the quality of hazard maps, including maps of potential hazards based on numerical simulations, as well as geochronology maps based on the study of recurrence periods. This paper presents two examples in which the use of GIS in the initial stage of a risk study facilitates obtaining information suitable for the implementation of hazard maps. The two case studies demonstrate how GIS can be integrated in a research dealing with the prevention of natural hazards, in perfect harmony with other techniques such as fi eld or conventional photo-interpretation. They also show that GIS are of great value in the communication of results to the organizations responsible for decision making.
