Discover four giant craters at 'the end of the world'

Scientists have discovered four giant craters in Russia's desolate Siberia Yamal peninsula - where three other large craters were discovered last year.

This raises fears that global warming may have caused the frozen soil to melt, causing methane to rise from the ground.

Experts predict that there may be up to 30 other holes that have yet to be discovered. Meanwhile, scientists have not yet determined exactly the process of forming these holes.

The first of the four new holes was discovered, named B1, showing signs that a major gas explosion had occurred.(Source: The Siberian Times)

Professor Vasily Bogoyavlensky, deputy director of the Institute of Oil and Gas Research in Moscow - a sub-institute of the Russian Academy of Sciences, called for an urgent investigation of this unusual phenomenon due to fears of possible carpeting. natural painting in the future.

'So far, we have discovered seven large craters in the Arctic region ,' the professor said in the Siberian Times.

'Five of them are located on the Yamal Peninsula, one in the Yamal autonomous region, and the other is in the northern Krasnoyarsk region, near the Taimyr peninsula. [.] I'm sure there are many other holes in Yamal, we just look for them. They are like mushrooms. If a mushroom is found, there will definitely be other mushrooms around. I think there may be 20 to 30 other holes here. [.] Don't panic, but this is a very serious problem. We need to research this phenomenon urgently to prevent future disasters. It is not possible to eliminate the possibility of gas leaks on the North Pole, and in some cases, this gas may explode. "

Professor Bogoyavlensky said that the pit walls show that this is the result of a gas leak from a shallow underground gas field. Earlier, scientists said there was much evidence that rising temperatures could be the main cause of these explosions.

One expert estimated that the explosion caused by pits could be equivalent to about 11 tons of TNT.
