NEW MASSIVE CRATERS APPEARING IN SIBERIA COULD BE CAUSED BY CLIMATE CHANGE - as underground methane gas may be heating up and igniting - At least one explosion was witnessed at one of the craters

Four new craters have been spotted by scientists in the Yamal peninsula, in Siberia

May be caused by gas from underground and fear craters becoming more common due to rising temperatures

Bright flash of light seen close to one crater which led to theories that buried gas pockets in the soil may be igniting 

Another new crater has been found less than six miles from a major gas plant and experts have called for an urgent investigation into the phenomenon 

Unexplained: The first of the new craters discovered, named B1 (pictured above), shows signs of an huge eruption of gas

Explosion? This crater (named B3) was spotted near to Antipayuta in the Yamal Peninsula after locals saw a flash of light nearby

 

Abyss: This crater, called B1, was first spotted 18 miles (30 km) from the Bovanenkovo by passing helicopter pilots

Last year scientists took a closer look at one of the older craters by climbing 54 feet down its frozen sides

When this crater was discovered in 2014, theories ranged from a man-made hoax, to aliens or a meteorite

The top satellite image shows an accumulation of ice beneath the surface, known as a pingo, while a more recent image shows a lake has formed in a crater scientists have called B2, surrounded by smaller holes

 

This map shows the location of the new craters (labelled B1-4) along with the previously discovered holes marked with black dots


Simmering: Methane gas can be seen bubbling up out of this lake in the Yamal region and is thought to be an old crater
