Landslide hazard analysis in national-scale for landslide risk assessment in Croatia

The objective of this study is preliminary national-scale assessment of the landslide hazard in Croatia using qualitative approach. Landslide risk analysis was done in the frame of Disaster Risk Assessment for the Republic of Croatia during 2018. Landslide risk assessment was carried out by the scientists from Croatian Landslide Group. As final result of conducted landslide risk assessment, landslides were recognised as the second natural risk in Croatia. Landslide hazard analysis included characterisation of the landslides and the corresponding frequency of multiple-occurrence regional landslide events (MORLE). The effects of controlling factors on landslide susceptibility was estimated using knowledgedriven method based on overlay of two landslide predictor maps, lithology and slope inclination. The analysis showed that approximately 20% of the area of the Republic of Croatia is potentially prone to sliding. MORLE records and precipitation triggering events were analysed to investigate the temporal probability of landslide hazard. Frequency of MORLE was conducted for two scenarios, the worst possible scenario based on landslide events in winter 2012/2013 and the most probable scenario based on landslide events in February 2018. Frequency analysis of precipitation triggering events showed that the most probable MORLE be expected once every 15 to 20 years and the worst possible MORLE once every 100 years.
