But now scientists have claimed the giant craters which suddenly appeared in Siberia over the summer may explain the mystery of the Bermuda Triangle.

Conspiracy theorists had alleged the holes were caused by meteorites, stray missiles from the Russian army or even as a result of aliens.

But experts said they were likely caused by explosions from gas hydrates which also may have led to ships and planes disappearing in Bermuda.

“They start to actively decompose with methane ice turning into gas.

“It happens in an avalanche-like way, like a nuclear reaction, producing huge amounts of gas.

“That makes ocean to heat up and ships sink in its waters mixed with a huge proportion of gas.

“The same leads to the air to get supersaturated with methane, which makes the atmosphere extremely turbulent and lead to aircraft crashes.”

Gas hydrates are ice-like forms of water containing gas molecules, notably methane.

They exist in permafrost regions such as northern Siberia, but also under the oceans in some parts of the world.

Three giant craters have been spotted in Siberia’s Yamal and Taymyr peninsulas during recent months.

“It turned out that there are gas hydrates both in the deep layer which on peninsula is several hundred metres down, and on the layer close to the surface.”

It is believed hot summer weather has melted gases trapped in layers below the surface causing craters to emerge in Siberia.

The phrase has also been used to describe the Bermuda Triangle.

The notorious region stretches from the British Overseas Territory in the North Atlantic Ocean to the Florida coast, to Puerto Rico.

The earliest know allegations of unusual disappearances in the Bermuda Triangle emerged in September 1950.

Among alleged explanations for the phenomenon are UFOs and leftover technology from the mythical lost continent of Atlantis.
