N2  - The objective of this study is to provide a simple methodology to conduct preliminary seismic assessment and ranking of bridge embankments in order to identify and prioritize embankments that are susceptible to failure. A ranking model that provides a priority list of embankments with the highest seismic risk of failure is generated. A step-by-step methodology is presented in a flowchart to estimate the seismic slope stability capacity/demand ratio, displacement, and liquefaction potential of bridge embankments. Three categories are presented to identify the failure risk of the embankments. The ranking model is useful for a quick sensitivity assessment of the effect of various site conditions, earthquake magnitudes, and site geometry on possible movement of designated embankments. The priority list will enable decision makers to decide on either carrying out further detailed evaluation or consider other appropriate actions for the bridge embankments with the highest seismic failure risk.<p />
