A gas emission crater is recent arctic phenomenon where melting permafrost releases enormous volumes of trapped gas in an explosive event. The holes were first spotted in 2013. Meanwhile, the first known crater "Yamal crater" (ru) in Yamal Peninsula was discovered in the summer of 2014; later, several dozen with more similar landforms were discovered. Soon it was proposed to call them in the scientific literature as "Gas emission craters". Known craters are located in the circumpolar regions of Western Siberia on land, on the bottom of rivers and lakes.
