Pan-European Landslide Risk Assessment

Associate Professor Mateja Jemec Auflič participated in a study on landslide risk assessment: from theory to practice. The theoretical part presents an overview of the key factors influencing the occurrence of landslides and the limitations of existing studies addressing landslide risk at local to regional level for the purpose of producing probability, hazard and risk assessments. In an experimental work, landslide data and geological and geomorphological characteristics of landslide-prone areas were collected for 13 European mountain ranges, including the Alps. Based on the statistical method Generalized Additive Models (GAMs), which allows flexible modelling of complex and non-linear relationships between predictor and target variables, a model for the probability of landslide occurrence, a model for hazard and a model for threat were first developed. The models were statistically validated using the random cross-validation method. The main outputs of the study are hazard maps of populated areas and agricultural areas and estimates of expected economic losses. The results are available through an interactive web application hosted on GitHub, where interactive features were developed using JavaScript in combination with the ArcGIS web application
