%X The importance of vulnerability to natural disasters studies is linked to the necessity of knowing spatially, which areas are more susceptible for the occurrence of natural hazards and extreme events and witch characteristics may increase the risk. The main objective of this work is to develop a methodology to calculate the vulnerability to extreme events, using spatial analysis techniques. The specific objectives include the creation of a database containing socioeconomics and infrastructure information at municipal level; the application of spatial analysis techniques to define the weights of the vulnerability to natural disasters factors; define the vulnerability factors and map the vulnerability to natural disasters. The geographic database containing information about the events and the socioeconomic data were processed in the software SPRING, which allows the integration of the information and the analysis of the existent relations between the different factors considered. These data were analyzed through the tool of support for taking decisions on the AHP (Analytic Hierarchy Process) technique, on for each indicator was ascribed a relative weight due its importance. For each analyzed events were generated three indexes, each one referent to a component of the vulnerability concept of Cardona (2001): physical fragility, socioeconomic fragility and lack of resilience. Reducing the vulnerability of populations to disaster is a crucial aspect of disaster management.
