The region of interest, stretching along the western branch of the EAR from Lake Tanganyika to the Rwenzori Mountains, is threatened by a rare combination of several types of geohazards, while it is also one of the most densely populated region of Africa. Landslides are possibly the most important geohazard in terms of recurring impact on the populations. Their occurrence is clearly linked to complex topographic, lithologic and vegetation signatures coupled with heavy rainfall events, which is the main triggering factor. The source mechanisms underlying landslide triggering and dynamics in the region of interest are still poorly understood, even though in recent years, some progress has been made towards appropriate data collection.

Taking into account difficulties of field accessibility, we present a methodology to study landslide processes by multi-scale and multi-sensors remote sensing data (Pléiades, TRMM, GPM, Sentinel, TANDEM-X). The research will combine such earth observation data with other data sources (rain gauges and seismic ground based networks, catalogues, field observations) to detect and study landslide occurrence, dynamics and evolution. This research aims to get insights into the rainfall thresholds that trigger and control the different types of landslide in this region of the East African Rift. Preliminary results for landslide inventory and deformation analysis with remote sensing will be presented.
