The 70m-wide crater appeared after the explosion lit up the sky

Residents on the Taimyr, Siberia peninsula saw the sky glowing after a booming explosion near 100km, leading to the birth of a mysteriously expanding mysterious crater.

According to Mirror, the crater was first discovered by reindeer shepherds who nearly fell into the hole after the explosion in 2013. At that time, the crater diameter was only about 4m with an estimated depth of 99m.Deryabinsky hole is now expanding into a small lake with a width of 70m. The permafrost in the pit wall is melting under the summer sun.

Dr. Vladimir Epifanov in Novosibirsk, Russia, collected details about the big explosion and went to check on Deryabinsky, the crater is the farthest place in the dozens of new pits that appear in northern Siberia. The villagers lived 72 to 97km away from the hole and still heard the sound of the explosion and saw the halo glowing in the sky, Epifanov said."The explosion is not like human work, but it does not seem like natural formation," said a witness.

The explosion took place a month after a large meteorite exploded in the sky of Chelyabinsk, causing local leaders to assume it was another celestial body falling into the area. Most experts believe that craters formed by methane explosion are triggered by warming temperatures in the far north of Russia . In particular, many craters on the Yamal Peninsula came into being due to pingo, domed mounds with ice cores, collapsing under the pressure of methane released from the permafrost of permafrost because of climate change. .

In the case of Deryabinsky pit, Dr. Epifanov gave another explanation. According to him, the ice burned over 500 meters above the ground, disintegrating, releasing methane. Methane gas accumulates at a depth of 99 m before exploding. Currently, Russia is monitoring satellite pingo stations to prevent new explosions in Siberia.
