Abstract: Landslides in northern Algeria and particularly in its eastern part are very common and affect large areas of land. The importance of studying the phenomenon, to understand its causes and mechanisms, to assess its evolution in time and space, has only developed when its human and especially economic damages were felt. Urban sprawl in this region, due to population explosion and the launching of major economic development projects such as dams, roads and rail infrastructure, have stressed the interest to address the issue. Due to the complexity of geological structures, the lack of accurate geological mapping and a reliable scientific research, the problem becomes more complicated.
Therefore the approach presented in this paper, consisting of photo-interpretation from aerial photographs and satellite images, combined with field investigations, provides a useful, practical tool in a relatively short time. It contains reliable information that accounts for the morpho-structural aspects and tries to relate the various detected and identified elements in order to provide appreciable answers regarding unstable zones. It also and guides / suggests further investigations for the less obvious cases.
