Resumen
A forest fire riskmodelwas designed and applied to a South AmericanMediterranean ecosystem, taking into consideration
three analysis groups: fire risk; danger of fire spread, or propagation; and damage potential over economic
threat values. The study area for development and validation of the modelwas theMediterranean zone of
central Chile and employed data fromhistorical records spanning a 14 year period (1997–2010). Territorial data
layers, combined with analysis of the statistical database and wildfire simulation have enabled areas of highest
vulnerability to be definedwith greater precision, especially in sectors associatedwith the urban–wildland interface
(defined as the zone where man-made structures meet wildland). Maps generated by this model have enabled
improvements to be made to the traditional mapping of fires currently undertaken in South American
countries. The results shown here are applicable to other Mediterranean areas, where modifications are made
to the entrance variables in the risk model
