The End of The World the slowpocalypse that is man-made climate change is this warming item from Siberia and Its Giant Holes:
Respected Moscow scientist Professor Vasily Bogoyavlensky has called for ‘urgent’ investigation of the new phenomenon amid safety fears.
Until now, only three large craters were known about in northern Russia with several scientific sources speculating last year that heating from above the surface due to unusually warm climatic conditions, and from below, due to geological fault lines, led to a huge release of gas hydrates, so causing the formation of these craters in Arctic regions.
Two of the newly-discovered large craters – also known as funnels to scientists – have turned into lakes, revealed Professor Bogoyavlensky, deputy director of the Moscow-based Oil and Gas Research Institute, part of the Russian Academy of Sciences […]
‘I think that at the moment we know enough about the crater B1. There were several expeditions, we took probes and made measurements. I believe that we need to visit the other craters, namely B2, B3 and B4, and then visit the rest three craters, when we will know their exact location. It will give us more information and will bring us closer to understanding the phenomenon.’
He urged: ‘It is important not to scare people, but to understand that it is a very serious problem and we must research this.’
In an article for Drilling and Oil magazine, Professor Bogoyavlensky said the parapet of these craters suggests an underground explosion.
‘The absence of charred rock and traces of significant erosion due to possible water leaks speaks in favour of mighty eruption (pneumatic exhaust) of gas from a shallow underground reservoir, which left no traces on soil which contained a high percentage of ice,’ he wrote.
‘In other words, it was a gas-explosive mechanism that worked there. A concentration of 5-to-16% of methane is explosive. The most explosive concentration is 9.5%.’
Gas probably concentrated underground in a cavity ‘which formed due to the gradual melting of buried ice’. Then ‘gas was replacing ice and water’.
‘Years of experience has shown that gas emissions can cause serious damage to drilling rigs, oil and gas fields and offshore pipelines,’ he said. ‘Yamal craters are inherently similar to pockmarks.
‘We cannot rule out new gas emissions in the Arctic and in some cases they can ignite.’
This was possible in the case of the crater found at Antipayuta, on the Yamal peninsula.
‘The Antipayuta residents told how they saw some flash. Probably the gas ignited when appeared the crater B4, near Taimyr peninsula. This shows us, that such explosion could be rather dangerous and destructive.
‘We need to answer now the basic questions: what areas and under what conditions are the most dangerous? These questions are important for safe operation of the northern cities and infrastructure of oil and gas complexes.’ 1
