Natural disasters involving soil movements are likely to occur in regions with irregular surfaces as Serra do Mar, a characteristic mountain range of the Brazilian coast, composed mostly by colluvium/talus deposits and residual soils. When slope failure occurs in highways, it can affect users and cause economic and environmental losses. Therefore, it is necessary to guarantee the safety during the lifetime of these roads. The stability of a natural slope is controlled by a complex interaction between hydrological and geological processes along with rainfall events of high intensity, which represents one of the main factors triggering slope instability. Thus, it is important to understand the relation between rainfall and mass movements. The main objective of this study was to analyze the mass movement occurrences recorded in the influence area of a rain gauge, located in km 140+700 m of BR-101 highway, in Santa Catarina, Brazil, and correlate them to the rainfall events registered by the instrument. The study period covers six years of monitoring, from July 2012 to June 2018, in which 16 occurrences were recorded in this area, in six different dates. The methodology was based in a pluviometric threshold and in the annual accumulated precipitation recorded. It was concluded that the movements were triggered by different accumulated rainfall scenarios, which depends not only in the rainfall event itself, but also in the distribution of the precipitation along the days preceding it. The correlations used identified short-time rainfall induced landslides and are an alternative to predict slope failures triggered by precipitation with these characteristics.
