“Doomsday Tiankeng” has something to say

  In July 2014, a huge bottomless hole suddenly appeared on the Yamal Peninsula in northern Siberia, Russia. The word “Yamar” means “the end of the world” in Russian, so the media referred to the strange pits here as “doomsday tiankeng.”
  ”Doomsday Tiankeng” suddenly appeared, very strange. The pit is about 80 meters wide and about 70 meters deep. There is an ice lake at the bottom.
  Initially, people thought that these strange holes might be traces left by aliens, and some people insisted that they were strange phenomena created by the whereabouts of meteorites, but there was no definite evidence to support these two wild conjectures. If a meteorite can smash such a large crater, the volume and mass of the meteorite itself should be relatively large, and it is impossible for it to enter the atmosphere without being detected by our various space exploration instruments. According to the current observation results, there was no record of asteroid impact at that time.
  A group of scientists rushed to the Tiankeng site to investigate, trying to study and analyze the cause of this strange phenomenon. After investigation and research, scientists have discovered that the formation of these magical tiankengs may be more bizarre than the above-mentioned causes. Tiankeng is located in Siberia, which is rich in natural gas resources in Russia. In addition to abundant natural gas resources, where latitude and altitude are relatively high, belongs to the permafrost region, according to the results of field visits, the experts gave some causes guess:
  1. Gas explosion said
  through visits found in the sinkhole edge darker, On the outside of the “doomsday tiankeng”, a lot of loose soil is stacked. Experts analyze that this is likely to be caused by the soil being pushed out of the hole. The Yamal region, where the “Doomsday Tiankeng” is located, is rich in natural gas resources and is Russia’s largest natural gas treasure house. The “Doomsday Tiankeng” is only about 30,000 meters away from the largest gas field in the Yamal region. The “tiankeng” is likely to be caused by the release of methane gas from underground caused by global warming, and the dark color on the inner edge of the cave may be a trace of gas explosion.
  Russian scientist Anna Kesatova believes that this area may have been the sea more than 10,000 years ago, and natural gas may accumulate in underground ice and then mix with salt. Due to the warming of the climate, the expansion of underground gas leads to excessive pressure accumulation. The mixture of water, salt, and natural gas burns underground, and then explodes, finally forming such a “doomsday sinkhole.”
  2. The sinkhole said that the
  ”doomsday sinkhole ” makes people think of the huge sinkhole in Guatemala. The two have many similarities. Therefore, some people speculate that the “doomsday sinkhole” is just like a sinkhole in Guatemala. Heavy rainwater or the impact of surface glacier melt water produces downward forces, causing the soil to sink. When encountering areas where there are inherently hollow terrain and karst landforms underground, vertical gaps may be formed. The surface water flows into the underground river through the cracks. Under the vertical action of the water flow, the cracks and cracks become larger, or due to insufficient soil support, it suddenly collapses under the pressure of the surface water, forming a tiankeng.
  3. mound of ice nucleation effect
  Dr. Fogeweier South Wales University in Australia, according to video images infer that the “doomsday sinkhole” with typical frozen landscape, is likely to be a collapse of the ice nuclei mound. In the high-cold frozen ground area, the water contained in the frozen-thaw layer of the frozen soil layer will slowly condense underground and freeze into a lens-shaped ice body called an ice lens. As water freezes and expands, a small hill will rise on the ground above the ice lens. Perennial ice core hills can uplift tens of meters in height and have a diameter of 30 to 70 meters.
  In summer, the ice lens body will melt due to the increase in temperature, which will cause the ground to sink, appear depressions, cause ground deformation, and even road boiling. The temperature rises rapidly in summer, the upper frozen soil layer quickly melts and the soil layer becomes thinner. At this time, if there is still a lot of gas inside, such as the “doomsday tiankeng”, an explosion may occur and eventually a pit like the “doomsday tiankeng” will appear.
  Whether it is gas dominance, hydraulic action, or the fragile permafrost layer created by the ice core dome, there is an unignorable inducement behind these causes-temperature rise. In addition to the summer warming effect, global warming is a more noteworthy hidden danger. Isn’t the frequent “sinkhole” phenomenon another warning from nature to us?
