AB - This paper describes advanced finite element simulations of a geologically active andperiodically unstable 700m high underwater escarpment located in the Gulf of Mexicothat has been created by uplifting salt diapirs combined with sediment deposition. Thesite's geological history, soil permeability and clay shear strength characteristicsgovern current slope stability and determine the timing of any future failure. Thegeological and geotechnical conditions are reported before presenting fully coupled,large displacement, numerical simulations employing critical state formulations of theslope's evolution over the last 600,000 years. The latter form the basis for strainsoftening analyses of the pore pressure equalisation and progressive failure processesthat control current slope stability. The analyses also address the ground movementpatterns that precede instability, giving useful information for geohazard riskassessment and early warning monitoring system design.
