Abstract: Since more than thirty years, the town of Constantine, witch is the third largest town in the north-eastern of Algeria has known serious damages to the dwellings due to the landslides. Its unstable urban perimeter presents some sites covering a total area of approximately 195 hectares that represent 3.9%of its urban space. The total population is about 15.38% which is equivalent to more than 100,000 inhabitants. This instability was clearly shown from 1970 to 1980. According to investigations, the lithology, the microtectonics, the water, the slope of the relief and the entropic actions are the main causes. To have a dimension on the extent of the situation and an idea on the progression of the damage caused to constructions some inclinometer field surveys have been carried out. Geological and geotechnical studies of the sites in question have been given a close attention.
