Abstract A simplified method for generating slope deformation hazard curve that takes into account the variations of input parameters is presented in this paper. The main assumption in the new approach is that the occurrence of peak slope deformation is Poisson׳s process. The procedure is based on logic tree analysis, commercial software and routines programmed by the authors for generating sets of input files, and forming slope performance curve. The methodology was applied to a real landslide in order to demonstrate the advantages and limitations of the proposed approach. The results of the analysis showed the influence of the certain input factors on sliding displacement as well as the advantages of employing continuum mechanics approach.

Highlights • The verification of the new procedure for obtaining slope deformation hazard curve. • Confirmation and quantification of the importance of treating the soil data variation. • The impact of shear modulus of sliding mass on slope deformation is highlighted. • The advantages of using advanced methods (continuum approach) are shown. • Confirmation of the applicability of the Newmark rigid block method in some specific cases.
