Fragility analysis of a pipeline under slope failure-induced displacements occurring parallel to its axis

•Continuum FE analysis of pipelines under longitudinal slope-induced displacements.•Characterization of uncertainty using fragility curves (10 uncertain parameters)•Fragility curve calculation methodology using the surrogate model technique.•A Random Forests, trained on a database of numerical results, is used as surrogate.•Uncertainty about the soil profile governs the pipeline performance.
