Sažetak

Apart from floods and earthquakes, landslides are among the most common type of natural disaster to occur in Croatia. Since landslides cause considerable economic and social damage, it is very important to detect and prevent their occurrence on time. In this paper, GIS analysis was used to calculate an inclined soil layer with defi ned classes of potential landslide hazards in the town of Lepoglava. This analysis considered factors that influence landslides, which are defi ned as landslide causal factors, i.e. those that have caused the existing landslides. These are morphometric factors determined by slope inclination and slope exposition, lithological and pedological structure, annual rainfall and anthropogenic influences. Using GIS analysis, an inclined soil layer of landslide susceptible areas and slope failure was calculated and fi ve different classes of relative landslide hazard were derived as follows: very low, low, medium, high, and very high landslide hazard.
