Evaluation of vulnerability and seismic risk parameters through a fuzzy logic approach

Abstract

Due to the geographical location of the Pacific fire belt, Ecuador is the scenery of natural phenomena such as earthquakes, which might be the main threat source on national territory and their intensity is likely to cause disasters, to facilitate the identification process of the risk level these disaster cause, we apply techniques of fuzzy logic, because related studies in this area have given more accurate results when working directly with the qualitative values of the data, allowing to deal with the uncertainty of the information on physical and social damages in a given area. For this study, the information was classified considering loss and immediate response scenarios, obtaining variables to which the Analytic Hierarchy Process (AHP) model and the fuzzy set theory were applied using the software ¨Matlab¨ for the evaluation of the results.
