North Algeria is very subject landslide Geo-phenomena, which causes each year very serious infrastructure damages and human lives. In order to estimate these damages and assess the effects of landslides on current development plans or future development programs, the analysis of the consequences seems like a very important criterion. Numerous approaches developed over the last decade, which have encountered difficulties in application, due to the lack of data on historical damage. This article presents a quantitative study of the potential consequences, based on GIS mapping in the Tizi ouzou area. The proposed methodology comports two principal stages ; the first identifies in a statistical way (Multiple correspondence analysis MCA) the correlations between the categories of exposed elements (land use, infrastructure, human) and the second phase consists in evaluating and mapping the damage potential of these elements using the technology of geographical information
