Tabriz is located on vast and gentle plain, in the east of Urmieh lake.It limited by different units of topography, lithology and geomorphology.In recently decades, physical development of city, has require, extent and repair of old roads and build of highways on the around of city. Unfortunately, the hurried performance of the development programs (as extention of transportation networks) and the impacts of human activities intensify activities of the morphogenic systems and cause the geomorphic phenomena as mass movements. This paper, using a Satellite image (Landsat ETM) and geographic information system.It emphasis with role of human activities, intensity of morphogenic factors and occurring different kinds of mass movement along roads and highways at the Tabriz city.The results, of this study, show that the landslides of Tabriz city are related with human factors (change of landuse, excavation of the base of slope).
