MYSTERIOUS CRATERS APPEARING IN RUSSIAN WILDERNESS - THEIR NUMBERS ARE NOW INCREASING

One of the craters is located in Siberia's Yamal Peninsula in the Taz district and has a diameter of 49ft (15 metres)

The other was spotted on the Taymyr Peninsula in Kransoyark region and has a diameter of 13ft (four metres)

They follow the discovery of a larger hole found in Yamal earlier this month at around 230ft (70 metres) in diameter

Andrei Plekhanov from Scientific Research Center of the Arctic says crater was formed due to rising temperatures

One theory is that a chunk of ice that is located underground created a hole in the ground when it melted

Another is that the crater was formed by a mixture of water, salt and gas igniting an underground explosion 

Theories range from meteorites, stray missiles, a man-made prank, and aliens, to an explosive cocktail of methane or shale gas suddenly exploding.
