Three craters that appeared in Siberia over the summer are thought to have been caused by huge underground gas explosions and could be 'the key' to the mystery of the Bermuda Triangle, according to scientists.

The holes – one in Taymyr peninsula and two in Yamal, known to locals in Siberia as 'the end of the world' – were the topic of much speculation, provoking suggestions that they were the product of alien invaders, meteorites, missiles or even a man made hoax.

Now scientists from the Trofimuk Institute of Petroleum-Gas Geology and Geophysics in Novosibirsk believe that they are the result of large underground gas explosions and could explain the disappearances in the infamous Bermuda Triangle.

The Siberian Times reported, that according to researchers from the Trofimuk Institute, warm climatic conditions from above the surface, and from geological fault lines below the surface, led to a huge release of gas hydrates.

"The main element - and this is our working theory to explain the Yamal crater - was a release of gas hydrates. 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," said scientist Vladimir Potapov.

Gases, methane in particular, are trapped in frozen hydrates below the permafrost (soil at or below the freezing point of water), and under some oceans, which researchers believe could be strong enough to bring down an aircraft or sink a ship, if they erupted.

"There is a theory that the Bermuda Triangle is caused by gas hydrates," said the Trofimuk Institute's deputy head, Igor Yeltsov. "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 the ocean heat up, and ships sink in waters which are infused with huge amounts of gas. This leads to the air becoming supersaturated with methane, creating an extremely turbulent atmosphere, leading to aircraft crashes".

The institute is continuing its analysis of the craters, so that all hypotheses are tested and to gain a better understanding of the holes to prevent future disasters.

"This was a recce trip that would allow us set agenda for the next trip, or trips, and give us basic understanding of what could have happened," said Potapov. "We must also pay attention to areas where the same thing might potentially happen."

Bermuda Triangle: Facts And Fiction

- It is also known as the Devil's Triangle.

- The 'triangle' is a loosely defined region between Bermuda, Florida and Puerto Rico.

- The area is one of the busiest shipping lanes in the world and also one of the busiest for aircraft flying down to Florida, South America and the Caribbean.

- In 1881, a ship called the Ellen Austin came across a derelict ship in the area and placed a crew onboard. They attempted to sail it to New York, but reports say that the vessel disappeared and then reappeared again, with no trace of the crew.

- A training flight of five torpedo bombers in 1945, vanished over the Atlantic. The disappearance is thought to be due to a navigational error which led to the aircrafts running out of fuel. However, one of the rescue craft deployed to find them also went missing with its 13 crew members.

- The incident resulting in the single biggest loss of life for the US Navy, was when the USS Cyclops set sail from Barbados, and then went missing sometime after 4 March 1918 with a crew of 309. No sign of the ship or its crew were ever found.

- One theory for the disappearances over the years is leftover technology from the lost continent of Atlantis, believed to be located beneath the waters there. Another theory is UFO kidnappings.
