Russian scientists use drones to solve the riddle of the giant “black hole” in Yamal

In the permafrost, rounded craters of the size of a 20-storey building are often formed, but scientists did not undertake to investigate them before. In Yamal, Russian specialists decided to take the first step towards unraveling the secret of this phenomenon and dropped drones into one of the karst formations, called “black holes”.

At the moment, scientists know a total of 17 such craters, moreover, they are formed in a wide variety of places and most often in those territories that are commonly referred to as permafrost. It was decided to lower the technique to the bottom of the giant black hole, first of all, in order to finally visually inspect the bottom of this strange natural phenomenon.

This study allowed Russian researchers to establish that the causes of the appearance of sinkholes are cavities in the soil, which are gradually filled with gas that can break out at a certain moment. It is at the very moment when the accumulation of gas rises upward under a pressure of about 12 atmospheres, and a similar explosive karst funnel of almost ideal round shape is formed.
