Methods for prediction of the post failure travel distance for landslides from cuts, fills and natural soil slopes are presented. The methods first require assessment of the likely mechanics of initial sliding, based on the material properties and slope geometry with a view to identifying if the subsequent travel of the landslide will be "rapid" or "slow". The post failure travel distance is then estimated for "rapid" slides from consideration of the slide mechanism, material type, slope geometry and/or slide volume; and for "slow" slides based on the residual factor of safety and estimated surface of rupture.
