In this article the results of the causal analysis and development of geological hazards in urbosystems are presented. The role of technogenic transformation of relief is defined. The conditions and factors of dangerous geological processes are considered on the example of the Tuapse city’s territory, and their role in the formation of the geo-ecological situation. It was revealed that due to the increasing anthropogenic pressure on natural systems these processes could be catastrophic and could bring a great harm to economy. As the example it is an analysis of the causes and consequences of the largest landslide in the last 30 years, which came down in February 2011 in Tuapse. A characteristic of engineering-geological conditions of the city is presented; their complexity is noticed, due to a complex of permanent natural and man-made factors, variety of styles, types and varieties of soils, a wide range of negative natural processes and phenomena. Nowadays an active role in the transformation of the urbosystems’ relief plays technogenesis. It was proved that in its manifestation of intense upsurge in geohazard is inevitable. It was revealed that landslides are the most common process, actively destroying the city. A scheme of arrangement landslides in Tuapse is presented. The main reasons for their development and human factors contributing their activation is considered. With the detailed study of the limitations of the development of the city it was established that the category of the danger of erosion, flooding and water damage is assessed in general as dangerous, and the category of landslide hazard and endogenous processes - both very dangerous. These processes (the affected area and the intensity of their development) are the limiting factor in the further expansion of the territory of Tuapse. With the trimming the slopes during the construction the modern geological processes will be activated, particular in landslides centers. It is noted that despite fact of the the high prevalence landslide processes the monitoring of the dynamics of their development is not conducted.
