Two months after it erupted, methane is still escaping from the Seyakha blowhole on the Yamal peninsula.
Fresh analysis of a new geological phenomenon shows how gas is still gushing from a submerged crater caused by a fierce methane gas explosion in northern Siberia in June.
A 'pillar of fire' from the eruption was caused by stones and pebbles being thrown together as they were thrust out of the ground, sparking the swoosh of gas, like in an oven, a leading expert believes.
Reindeer and dogs from a nearby nomadic encampment fled in terror at the fireball, with some debris thrown as far as 200 metres from the epicentre.
A 50-metre deep funnel or crater was immediately filled by water from the Myudriyakha River flowing beside the site of the explosion.
Dr Anton Sinitasky, director of the Arctic research Centre in Yamalo-Nenets region [...]said: 'I can confirm that there was really a fire burning over the Seyakha funnel. We need to rely on the words of eyewitnesses. It lasted for one or one-and-a-half hours.
'Everything depended on the gas jet power.
'We think that the cause of the ignition was pebbles thrown by the eruption.
'The pebbles collided and struck a spark.
'It was like in gas oven - one spark was enough to set the gas on fire.
'When the power of gas jet began to decrease, the burning stopped.
'But the methane continues to leak from the funnel, so we have been able to take samples.'

The russian humor (sarcasm?) about it is to admire in the video. Playing "Highway to hell" with earth turning upside down.  :o :o :o

The interesting bit to me being:

"It is all about monitoring,' said Dr Sinitasky.

'I know that oil and gas producing companies have maps of such objects and monitor them constantly.

'I have heard that for example Gazprom-Dobycha Yamburg make punctures and release gas to avoid eruption risk.

'When I was working at VNIIGAZ, I made a map of such objects for Gazprom.'

He said: 'The companies are very interested in minimising risks, they do not need any accidents, so they make maps and observe these objects very closely.

'As for the general map of such objects... The Institute of Oil and Gas Problems keeps a database on sites being discovered using satellite data.
The Earth Cryosphere Institute probably has its own database.'

Puncturing pingo's ey?
It would be nice if the good folks at Gazprom shared some footage of that...
