The White Mountain area in the city of Nablus, Palestine, had severe landslides in the year 1997.necessary studies to find out the causes and to overcome this problem were carried out. This included surveying of the area, geotechnical studies (digging out five boreholes, taking necessary samples, and conducting laboratory tests), and slope stability analysis. The factor of safety was found to be more than one (between 1.4 and 1.8), and this indicated factors other than the natural slope caused the sliding in the White Mountain. It was found that the main causes of landslides were the cuts in the lower part of the area.
