- Аннотация: This paper presents the characteristics of the relief in the area of crater formation in Central Yamal based on the analysis of remote sensing data, including stereo-pair very high-resolution data, as well as field observations. The time interval of the crater formation was defined as late fall 2013. Data on the morphology of the studied area before and after the crater formation were obtained. The existence of a bulge with the base diameter 45–58 m and the height of about 5–6 m in place of the crater was documented. Analysis of multi-temporal digital elevation models allowed calculating the volume of the crater void and the parapet formed around it. The volume of discharged material was determined to be nearly 6 times larger than the volume of material found in the parapet. The difference is due to a significant amount of ice, which, according to the results of field observations, was exposed in the walls of the cylindrical portion of the crater, and, apparently, comprised a major part of bulge material that got thawed after the ejection. The rate of the crater increase in diameter due to melting of its ice walls and the rate of its filling with water over the summer period were determined
