Abstract
The management of major landslides faces several difficulties especially when important stakes are exposed to risk. The landslide of the city Azazga is one of the most extensive cases observed in Algeria. This is an instability reactivated by specific climate events such as floods of 1974 and snow of 2012. Landslides affect the center town of the region of Azazga situated 20 Km East of Tizi-Ouzou (northern Algeria). They affect a highly urbanized area and endanger vital structures such as the regional hospital. Managing this risk requires the development of an effective management methodology as well as a good knowledge of site conditions, the causes and the extent of the landslide. To better characterize this extensive instability, a geographic information system was created for the study site. This GIS greatly facilitates the interpretation of spatial data.
The aim of this work is to investigate the potential risk posed by landslides in the city of Azazga. This potential is estimated from observations and exploration of the site using the method of Djerbal and Melbouci (2013). A risk management methodology is then developed for this site. The results obtained show that the very strong hazard affects a large area of the city Azazga.
