Bulging bumps in the Yamal and Gydan peninsulas believed to be caused by thawing permafrost releasing methane
Scientists have discovered as many as 7,000 gas-filled ‘bubbles’ expected to explode in Arctic regions of Siberia after an exercise involving field expeditions and satellite surveillance, TASS reported.
A number of large craters – seen on our images here – have appeared on the landscape in northern Siberia in recent years and they are being carefully studied by scientists who believe they were formed when pingos exploded.
Alexey Titovsky, director of Yamal department for science and innovation, said: ‘At first such a bump is a bubble, or ‘bulgunyakh’ in the local Yakut language.
‘With time the bubble explodes, releasing gas. This is how gigantic funnels form.’
