The reason for the horrific big death pit has been constantly appearing in Russia

Unusual natural phenomena appear on the Yamal Peninsula, north of Russia since 2014, recently believed to have been answered.

According to Daily Mail, the mysterious death hole first appeared in Russia in 2014, raising speculation about a missile test, or alien creation.

Deathhole first appeared in 2014.

The death holes continue to appear in large sizes where there are no different, deadly holes in the countries of the world.

Typically, the death hole of Batgakia in Siberia, which the locals call 'The door to hell'. Every day, this crater further expands and reveals a mysterious land 20 thousand years ago. With a width of 1km, 65 meters deep, each year Batgakia death hole is blooming from 9 to 30 meters.

Scientists later agreed that this death-type pit in Russia was formed by frozen gas methane eruptions.

Giant death tiger appeared more and more in Russia.

Most recently, from satellite images, scientists believe that there is a more specific reason to explain why a death pit appears so much.

Professor Vasily Bogoyavlensky from Moscow Petroleum Institute said that this phenomenon is partly caused by 'human hands'.

The death pit is said to be related to the exploitation of natural gas.

Mr. Bogoyavlensky said that Russia's increased exploitation of natural gas to export to Europe and China is the main reason. Mining activities cause unstable methane air bags in permafrost.

Gas accumulates under the ice for a period of time, then the air bags explode, Professor Bogoyavlensky explained. The amount of natural gas in Yamal plays an important role in the Russian economy.

Experts say the death hole forms part of the "human hand".

'To some extent, the volcanic eruption mechanism takes place here, the accumulation pressure and the release phenomenon take place. The situation then became stable , 'said Professor Bogoyavlensky.

It is estimated that there are dozens of death pits appearing in Russia within the last 3 years. Mr. Bogoyavlensky called for careful monitoring of geological activity to identify new death zones that could appear near oil pipelines or residential areas.
