Yamal funnels

Blocks of soil and ice thrown hundreds of metres from epicentre of the funnel at the Yamal peninsula.

Scientists rush to site of latest tundra eruption - which formed a crater 50 metres deep - amid fears for homes and key industrial sites.

Pipes are built over bulging and unstable Arctic pingos prone to violent eruptions caused by 'thawing methane gas', as seen twice on the Yamal peninsula this year.

Bulging bumps in the Yamal and Gydan peninsulas believed to be caused by thawing permafrost releasing methane.

Dissecting them like surgical abscesses to release the gas seen as one solution to avoid future eruptions.

200 metres wide thermocirque seen weeks after scientists find funnel in the Yamal peninsula, caused by build up of methane.

Local reindeer herder witnessed the tundra explosion that led to birth of new hole in river.

Gas bubbles from waters filling crater hole on Yamal peninsula two months after volcanic-style explosion in thawing permafrost.

Man ‘caused some of the tundra blasts forming the large holes’, says leading scientist in surprising new theory.
