<p>This study developed a novel landslide risk assessment framework to analyze landslide risk in Mt. Umyeon, Korea. The proposed framework included four main procedures: (1) Landslide hazard analysis using an ensemble statistical and physical model, (2) Analysis of physical vulnerability from vulnerability curve, (3) Analysis of physical vulnerability from semi-quantitative approach, (4) Risk index calculation from the results of previous steps using a proposed equation. The results of each step were compared to real landslide events occurred in July 2011 at Mt. Umyeon, Korea to confirm the reliability of the proposed risk assessment framework. The risk maps also were compared to real landslide event and showed that the proposed framework was successful in assessment of landslide risk at Mt. Umyeon, Korea. The new concept in landslide risk assessment of this study provides reliable decision-making in landslide risk assessment and management.</p>

Abstract. Physical vulnerability is a challenging and fundamental issue in landslide risk assessment. Previous studies mostly focus on generalized vulnerability assessment from landslides or other types of slope failures, such as debris flow and rockfall, while the long-term damage induced by slow-moving landslides is usually ignored. In this study, a method was proposed to construct physical vulnerability curves for masonry buildings by taking the Manjiapo landslide as an example. The landslide's force acting on the buildings' foundation is calculated by applying the landslide residual-thrust calculation method. Considering four rainfall scenarios, the buildings' physical responses to the thrust are simulated in terms of potential inclination by using Timoshenko's deep-beam theory. By assuming the landslide safety factor to be landslide intensity and inclination ratio to be vulnerability, a physical vulnerability curve is fitted and the relative function is constructed by applying a Weibull distribution function. To investigate the effects of buildings' parameters that influence vulnerabilities, the length, width, height, and foundation depth and Young's modulus of the foundation are analysed. The validation results on the case building show that the physical vulnerability function can give a good result in accordance with the investigation in the field. The results demonstrate that the building length, width, and foundation depth are the three most critical factors that affect the physical vulnerability value. Also, the result shows that the higher the ratio of length to width of the building, the more serious the damage to the building. Similarly, the shallower the foundation depth is, the more serious the damage will be. We hope that the established physical vulnerability curves can serve as tools for the quantitative risk assessment of slow-moving landslides.

Landslide Risk Assessment

Landslides are unavoidably linked to forestry operations in coastal BC. A neglected component of landslide risk assessment is the degree to which impacts from landslides may be acceptable. One hundred and thirteen professionals in the BC forest industry, including foresters, biologists, geoscientists and engineers, examined landslide tolerability criteria. Despite differences by sector, there was general agreement that landslides resultant of ignoring expert advice or where an expert was clearly at fault were unacceptable, and penalties were high. In more ambiguous cases, increased consequences resulted in increased scrutiny and it was clear that experts should expect to be held responsible for their decisions by government officiators and the public. Key words: landslide, risk, risk perception, acceptable risk, landslides and forestry
