Same phenomenon of discharge of gas hydrates 'led to crater formation in Russia and disappearance of ships in Atlantic'.

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

High levels of ‘fire ice’ trapped in permafrost may turn Russia into a global leader of new gas sources.

More craters expected to form due to such eruptions as permafrost melts - and they ARE caused by global warming releasing methane gas.

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.

Warning of methane blasts in Kara Sea adjacent to Yamal craters caused by gas eruptions associated with melting permafrost due to global warming.

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