Methane Sinkholes in Siberia !

Sinkholes are often associated with karst/ limestone. But Russian scientists have discovered in Siberia a new type of Sinkhole


 A number of craters have appeared across Siberia over the past few years, with the first spotted in 2013 by helicopter pilots 20 miles from a gas extraction plant at Bovanenkov. The second was in the same permafrost region of northern Russia, and the third on the Taymyr Peninsula, to the east, in the Krasnoyarsk region. The scientists believe warming air is melting the thick permafrost, leading to the accumulation and release of volatile 'fire ice' gases which then explodes to create the giant funnels.They believe there is growing evidence that rising temperatures were catalyst for massive unexplained holes in ground.
