Abstract
AbstractThis chapter reviews the methods used to carry out coseismic landslide susceptibility and slope stability analyses, from the regional- to the site-scale and based on user needs, data requirements and constraints. Earthquake-induced landslide (EIL) triggering metrics (ground shaking) are discussed and linked to landslide severity and other environmental impacts likely to occur at different levels of ground shaking. Six case studies are used to explore the various methods of determining coseismic landslide susceptibility and slope stability analyses, the metrics they produce, the scale of applicability and data requirements. The key developments and challenges of each method are discussed and summarised. One such challenge is that the efficacy of each method is limited by the availability of the input data and/or the ability to derive it, irrespective of the project scale or need. Possibly the largest challenge for experts is the ability to transfer the results from such models into actionable information (e.g. hazard and risk analyses and engineering design) to support science-based decision-making.
