24. Development and Application of a Regional Slope Stability Assessment Screening Tool

This article describes the development of a screening tool to estimate factors of safety and probabilities against slope failure for static and pseudo-static analyses, as well as seismically induced permanent displacements, for both onshore and offshore slopes. The screening tool combines geophysical and geotechnical data to rapidly assess and identify potentially unstable regions over large areas. The results allow a quick, objective, and logical rationale for selecting regions to perform more in-depth and detailed slope stability analyses, and/or areas to avoid when selecting locations or paths for future infrastructure development. We apply the screening tool to part of the continental slope offshore the Lofoten islands, Norway.
