The present invention relates to a landslide hazard analysis system and a method thereof, more specifically, to a system and method for analyzing a future landslide hazard considering a climate change by organically fusing individual technologies in comparison to conventional technology related to landslide occurrence which is individually performed like landslide susceptibility production utilizing geographic information. To this end, the landslide hazard analysis system according to the present invention comprises a landslide information collection unit, an item extraction unit, a normalization unit, a statistical analysis method application unit, and a landslide susceptibility derivation unit. The landslide information collection unit collects landslide-related information and geographic information of aerial photography information. The item extraction unit analyzes the collected information to extract an item related to landslide occurrence. The normalization unit corrects and normalizes attributes information and geographic information related to the landslide occurrence based on the extracted item. The statistical analysis method application unit applies the normalized information to one statistical analysis method among a frequency ratio, a logistic regression, and a neural network. The landslide susceptibility derivation unit derives landslide susceptibility at the present time on the basis of the applied information.
