Abstract

Mass movements are one of the most active and impactful phenomena related to disasters. In Brazil, the landslide are compounded by a number of factors such as the presence of massive mountain associated with certain favorable climatic conditions, as occur in the Região Serrana of Rio de Janeiro state. In this sense, the present study aims to analyze the influence of conditioning factors on landslide in the Paquequer River Basin (Teresopolis, RJ) in order to generate a Susceptibility Map of land to these events based on multi-criteria analysis AHP and Weighted Average. We correlated 10 conditioning factors to landslide inventory map where, from which, we applied a weight to each correlation to obtain the susceptibility map. About 77% of the points mapped movements are in High class and Very high susceptibility, occurring mainly in areas with slopes between 8-100%, with intense rainfall, located in areas subject to human influence, or rugged areas.
