The mystery of explosive craters.

We have another mystery, this mystery seems to have a solution in the craters of Siberia, permafrost is what is known as the frozen soil that exists in the regions near the poles or in the high regions, for example, on the Tibet plateau, Permafrost is a mixture of ice, water, rocks, mud, some mammoth and all of it frozen, the ice acts as a kind of cement uniting all of this when the temperature increases it thaws and the ground sinks, it is a known process. and there are several cases but this is not that specific case.

This hole above is not that case of soil subsidence due to the thawing of the permafrost, it is another different case that has also been a mystery for scientists and is that of explosions, because this crater of an explosion, explosions have occurred that They open craters by drilling up to 150 meters of permafrost and it is an enigma that scientists have been trying to reveal since at least 2014 when the first crater of this type was detected, it had 30m wide and burst into ground that had previously been frozen for hundreds of thousands of years, many more of these craters have since opened.

8 years ago, helicopter pilots flying over the Yamal Peninsula in Siberia discovered a spectacular crater, one of the largest, it was a crater that seemed to have swallowed hundreds of square meters of earth and extended more than 52 meters deep, now it is has published a paper by researchers from the University of Cambridge in England and the University of Granada in Spain that details how and why these craters form.

According to these researchers, apparently beneath that frozen permafrost land there is a layer of solid or frozen methane, in the form of methane hydrates, sometimes there is also a third layer that is hidden between the sediment and the methane bed, they are pockets. of salty liquid water called cryopeg, according to scientists cryopeg are formed when warmer surface temperatures cause the frozen glue of the permafrost to melt, but that melted water goes down and that water, as it goes down, forms puddles of liquid as it As the puddles grow, so does the pressure beneath the permafrost, and eventually cracks form on the surface on a large enough scale. These cracks produce such a rapid drop in pressure that the methane hydrates break apart explosively, producing these gas explosions. methane.

It is curious, basically it tells us that there are enormous reserves of methane gas under these frozen soils and apart from being very dangerous due to the explosions they cause, it is methane that is released into the atmosphere and therefore also contributes to increasing the gases. greenhouse effect, so we should take into account how much methane released influences global warming, what do you think about the subject, it is a shame that so much methane gas is lost because methane gas is also a source of energy, it is a shame that it is lost and the atmosphere also leaves so that it also ends up creating greenhouse gas.
