The factor of safety is one of the major aspects for designing specific structures like embankment, landslide, and artificial slopes. In this context, some huge damages are particularly reported due to the effect of earthquakes. In this paper, 700 slopes were designed based on the limit equilibrium method, and relevant factor of safety values were obtained. In the modelling process, the parameters with the greatest effect (slope height, slope degree, soil cohesion, and internal angle of friction with peak ground acceleration), were considered as predictors or model inputs. As a result, the factor of safety under the impact of seismic motion is significantly reduced when the peak ground acceleration increases. A multiple regression model was developed. Coefficients of determination for the training and testing datasets indicate the excellent ability of the proposed model to estimate the seismic factor of safety. Peak ground acceleration and soil cohesion were obtained as the parameters with the most and least effect on the factor of safety, respectively.
