The mysterious giant craters of Siberia, with an impressive depth of around 164 feet, have sparked the curiosity of scientists for over a decade. A new theory, detailed in a. ....
Vasily Bogoyavlensky, geologist and geophysicist, said that there are many of such black holes in the north of Russia. Many of those craters have emerged during the past ten years. The very first crater, which was discovered in 2014, became the famous one. It was a hole about 50 meters deep and 40 meters in diameter. Geologists quickly established that the giant hole in the ground was just a hole, from which methane was bursting out. A cavity is formed in the layers of underground ice as it melts due to the influence of a local anomalous heat flow. This cavity is then filled with gas, and it grows larger, causing the surface on the ground to swell until the frozen rock reaches its ultimate strength and eventually explodes in a pneumatic explosion. ....

Credit: Evgeny Chuvilin Researchers from the Oil and Gas Research Institute of the Russian Academy of Sciences and their Skoltech colleagues have surveyed the newest known 30-meter deep gas blowout crater on the Yamal Peninsula, which formed in the summer of 2020. The paper was published in the journal Geosciences. Giant craters in the Russian Arctic, thought to be the remnants of powerful gas blowouts, first attracted worldwide attention in 2014, when the 20 to 40-meter wide Yamal Crater was found quite close to the Bovanenkovo gas field. The prevailing hypothesis is that these craters are formed after gas is accumulated in cavities in the upper layers of permafrost, and increasing pressure ultimately unleashes an explosive force. Most of these craters are rather short-lived as they apparently quickly fill with water over several years and turn into small lakes. As of now, there are some 20 known and studied craters. ....
