This manuscript presents the results of an analysis, parameter by parameter, that affect the displacement of a slope when subjected to dynamic loads. The effect of the shape of the dynamic record through parameters such as frequency, amplitude and duration is evaluated. Also, the soil characteristics are investigated considering the specific gravity, Young's modulus, Poisson's ratio, cohesion, friction angle and damping. The displacement of the crest of a slope can indicate the performance of stability, hence the use of numerical techniques such as finite element helps to understand the effect that an earthquake (dynamic load) could have on the generation of deformations. Traditional methods such as pseudostatic and Newmark do not consider the characteristics of the earthquake. To better capture the effects of an earthquake, parameters such as frequency, amplitude and duration should be considered as to make a reliable estimate of displacements, which can be done by a dynamic analysis using finite elements.
