The study investigates the risks to mass movements on slopes in the region of Viçosa - MG, in representative areas previously classified as high potential natural hazards. Searching up to it, diagnose the slopes in the urban area of the city in various scenarios and analyze its stability from its own geological and geotechnical characteristics of the terrain. For this to occur , the research made use of the Pressuremeter Ménard field test - PMT, due to its versatility and reliability in obtaining the parameters of soil strength in depth, detailing what each meter, allowing the identification of failure mechanisms by analysis. The research was based on risk rating maps to mass movements, surveys, field tests and simulations to determine the degree of instability of these areas and their respective safety factor. With this in hand, has become an important base which allows the municipality to create and plan appropriate public policies to each type of Field geological and geotechnical information.
