Abstract: This work describes research of southern and southeastern hills of Medvednica Mt. in the City of Zagreb encompassed by the boundaries of the landslide inventory from 1979 which was created by Geotehnika-Geoexpert, with the total area of 105 km2. Numerous landslides at the area pose a threat to the local population and property. Data about landslides at the hilly area of the Zagreb city (Podsljeme area) was systematically collected three times in last 50 years. This three historical landslide inventories shows that there are significant differences in number of identified landslides as well as in its size. High differences between historical data on landslides in the Podsljeme area indicate the unreliability of the data about landslides in existing inventories. The general objective of the diploma thesis was statistical analyses of landslide inventory from 1979 in order to gain insight into the typical landslide size of Podsljeme area. Specific objectives were digitization of landslide inventory analogue map, statistical analyses of active and inactive landslides and creeping sliding phenomena and interpretation of results due to the characteristic size of registered landslides and size estimate of potential landslides. Statistical analyses encompassed 931 landslides and 65 creeping phenomena with the size from 0,41 to 289.341 m2. Landslide density at the area of the inventory is 9,5 landslides per square kilometer, i.e., 6,2% of the inventory area, and its total area is 6,5 square kilometer. Results of statistical analyses were compared with the analyses of the inventory from 1979 described in the PhD thesis Podolszki (2014) which are as follows: 812 landslides with the area from 454 to 289.501 square kilometer, total landslide area of 9,1 km2, i.e., 8,7% of the inventory area. Landslide frequency differs for active and inactive landslides and creeping phenomena and for landslides with reliable and unreliable determined landslide contours. Generally, maximum frequency have landslides ranging from 1.995 to 2.511 m2 in which are 80 landslides or approximately 8,03% of all landslides and creeping sliding phenomena of inventory. The research results confirmed high density of landslides in the Podsljeme zone but their average size is less than the average size of the landslide in existing inventories. The dominant landslide types are small and shallow landslides, which are most frequently triggered by precipitation and man-made activities.
