Scientists found many underground gas pingos (mounds of heaving) on the Yamal and the Gydan peninsulas. In course of time they can blow up, in this case emission of gas will happen and a funnel will be formed. This information was confirmed to a correspondent of IA “Sever-Press” by the director of the department on science and innovations of Yamal Aleksey Titovskiy. As he notes, it is difficult to tell the precise number of such bubbles. Pingos are seen well from satellites, on cosmic images, and this natural phenomenon is characteristic not only for the Arctic. According to his words, they can be hundreds and thousands, but the problem is not in their number. It needs to think, which of them can be the threat. The methodology that allows defining dangerous pingos and their stage of heaving is being elaborated in the region. The scientists are busy with defining of signs: limits of a pingo height, maximum pressure that the ground can withstand. It will help to forecast a blow up and to minimize its consequences.
Scientists of Moscow Oil and Gas Research Institute, Novosibirsk Institute of Oil and Gas are elaborating the methodology. Also, according to the director of the department, scientific community of the companies “Gazprom”, “Yamal LNG” and “Total” have joined to the research since discovery of the first funnel on the Yamal Peninsula in 2013.
Aleksey Titovskiy reminds that in the near future seismic sensors will be installed in Bovanenkovo, Sabetta and Kharasavey to monitor the situation and to build the forecasting system. In the scientific article a corresponding member of the RAS, doctor of technical sciences Vasiliy Bogoyavlenskiy says that such dangerous natural phenomena as funnels of gas emissions occur along seismic faults. Therefore, it is impossible to claim that funnels appear only as a result of global warming. Probably, this is a combination of several factors, as the director of the department says.
The information from the sensors will be transmitted by satellites to the scientists, who will be able to process, interpret and transmit data. Thus, if somewhere on the Yamal Peninsula ground tremors or gas emissions take place, specialists will know for certain, when and where it happened.
Also Aleksey Titovskiy notes that there are about 300 thousand lakes in Yamal. In the opinion of the scientists, a greater part of them is formed of underground mounds of heaving. He underlines that there is no evidence that this phenomenon is technogenic.
