Scientists spotted the new holes, along with dozens of other smaller ones, in the same area as three other enormous craters that were spotted on the Yamal Peninsula last year. The craters are thought to be caused by eruptions of methane gas from the permafrost as rising rising temperatures causes the frozen soil to melt. Experts have predicted there could be up to 30 more are waiting to be discovered.
It has sparked fears that the craters could become more common as climate change continues to warm and led to warnings that the area is facing a looming natural disaster.One of new craters, surrounded by at least 20 smaller holes, is just six miles from a major gas production plant. Scientsts, however, are still largely baffled by the exact processes causing the craters.
