As a result of the analysis of aerospace, geological and terrestrial information, it was established that the main cause of the natural and technogenic catastrophe on 06.06.1997 on the territory of Topol-1 in the city of Dnepr is the activity of a man who allowed technogenic overload of the geological environment. Due to the dense development of the eastern slope of the beams by high-rise buildings, technogenic loads have significantly increased, tectonic, geodynamic, geological characteristics of the plateau, hydrogeological regime and engineeringgeological properties of loess soils and underlying clayey waterproof have been disrupted. When laying foundations under the buildings to a depth of 30 m, the natural structure of the forest was also destroyed here. This led to the disruption of the stable functioning of the natural geosystem on the slope of the beam, the destruction of tectono-hydro-lithogenic bonds in mountain-rock complexes, an increase in the groundwater table, a significant weakening of the bearing strength of loess soils, the destruction of foundations of buildings and underground utilities and, ultimately, Catastrophe. The situation here was further aggravated by torrential rains that passed on the eve of the landslide.
