Abstract This paper presents a brief summary of multi-hazard risk assessment, focusing on cascading landslide hazards. It starts by presenting the multi-hazard processes an engineering system may face, and possible interactions among the separate hazards and between the vulnerabilities of elements at risk to these hazards. Then a framework for analyzing the flooding, landslide and debris flow processes in a rainstorm is introduced. Multi-hazard risk assessment requires more comprehensive physical analyses than what are needed in conventional geotechnical design. Stability analysis, flow analysis and impact analysis are all required. The outcomes of such physical analyses form the basis for evaluating the risks associated with these multi-hazardous processes. The multi-risk analysis can be performed using a HKUST five-step procedure, which describes the hazardous processes in an explicit probabilistic framework and identifies key parameters that govern the success of a risk mitigation effort. Rational engineering decisions and emergency management policies can be made based on such physically-based risk analysis.
