Bukavu has always been subject to natural processes of erosion, transport of large masses of materials and deposit-sedimentation. The natural causes of these phenomena are the important relief and tropical rains, the weathering of rocks related to the tropical climate and the presence of active faults and earthquakes connected to the rift activity. The present work focuses on the landslides of Ibanda, in Bukavu town. An inventory of 14 landslides has been completed. A statistical analysis of various parameters (slope, slope orientation, distance to drainage and distance to slop) was made using GIS (Geographic Information System) to describe their influence in triggering landslides. We found that all these parameters do not have more influence on landslides activation, people are playing a big role on activation by looking for ground to build house. The weighting of these parameters allowed us to map the landslide hazard.
