Dangerous geological processes on Lake Kolsai and the impact of Anthropogenic load on the DGP

Abstract

This article shows research the risks of landslide processes on the territory of Lake Kolsai, as well as the influence of anthropogenic factors on dangerous geological processes. Examples of data processing from LandSat-7,8 satellites using the Google Earth Pro program and images of the territory of Lake Kolsai using unmanned aerial vehicles are shown. The main purpose of this article is to use the analysis of data from previously carried out works to assess the conditions of zones with potentially dangerous development of landslide processes, as well as to give predictive assessments of the risks of DGP in this area. The area of research is the left side of Lake Kolsai in the northern Tien Shan, in the Kolsai Gorge, in the bridge connecting the Kungei and Zailiysky Alatau ridges. At the end of the nineteenth century, a number of major earthquakes occurred in the above-mentioned area, which caused enormous damage to the environment and to the people of the coastal areas. Subsequently, after these earthquakes, dangerous zones with a potential risk of landslide processes were formed in the study area. This article deals mainly with the left side of Lake Kolsai, which changes year after year due to the strong anthropogenic load. For this article, the collected satellite images and photographs from the UAV have been processed, interpreted and the necessary data extracted. The analysis of previously carried out works is made.
