Generally, slope stability analyses are carried out using the two-dimensional analysis methodology, which provides a more conservative security FS, and given that rock falls occur on the Costa Verde every time an earthquake occurs, it is proposed to perform a sensitivity analysis between the two-dimensional and three-dimensional methodology. Since two-dimensional analyses carry out a significant simplification of the geometric shape of a slope this method tends to provide us with conservative and in some cases unrealistic values. In the present investigation, a sensitivity analysis of slope stability was developed using the limit equilibrium method for geotechnical parameters such as cohesion, friction angle, and specific weight. Calculations were used using the simplified Bishop, Morgenstern-Price, and Spencer methods, for the static and pseudo-static models. These methods were analyzed on a slope with the geotechnical parameters predominantly consisting of fines and another of conglomerate. In the two-dimensional analysis, the friction angle was found to be the most sensitive, while the most notable aspect of the three-dimensional analysis was the different locations of the failure surface according to the calculation model used, whether simplified Bishop, Morgenstern-Price, or Spenser. Two-dimensional analysis is a useful and practical tool, it does not require many computational resources, it gives us a conservative FS, while three-dimensional analysis requires more information, and processing time, but gives us a much more realistic possibility of analysis.
