The relief of the east coast of the Bay of Santiago de Cuba has been modified by anthropic action, which together with the conditioning variables such as geology, slopes and hydrography make this area of moderate susceptibility to landslides, assessing this antecedent the main objective is to determine the safety factor of a slope near the Bella Vista motel, east of the bay of Santiago de Cuba, to define its stability, level of hazard for the road and consequences to the environment. The plane break was considered and the methods of infinite slope without and with infiltration are used. The elements that lead to instability were analyzed, such as geometric, geological, hydrogeological, geotechnical and seismic hazards. Spreadsheets were used as a tool that allowed the solutions to be obtained quickly. As a result, the safety factor was obtained by the infinite slope with and without infiltration methods, noting that for the thicknesses from 0.5 to 3m it turned out to be a stable slope that offers no hazard to the road; therefore there are no effects to the environment.
