Abstract

In Turkey, landslides are the second most common natural disasters that cause damages in Turkey that follow the earthquakes. Thus, landslide risk assessment is of crucial importance in this area. Therefore in this study a quantitative approach for mapping landslide risk is developed for property and life at local scale. The approach is first based on the identification of existing elements at risk in the area by the developed algorithm. Then the vulnerability approach focuses on determination of quantitative vulnerability values for each element at risk by considering temporal and spatial impacts by adopting a “damage probability matrix“ approach. The loss estimation was combined with the hazard values which are based on former work done in Bartın Kumluca area where a detailed study of landslide occurrence and hazard in the recent past (last 30 years) was carried out. The final result risk maps for property ($/pixel/year) and life (life/pixel/year) shows all losses per pixel annually for each element at risk in Hepler village.
