Mysterious Siberian Crater Is Just One of Many 88
New submitter Sardaukar86 sends this excerpt from a Washington Post report:
In the middle of last summer came news of a bizarre occurrence no one could explain. Seemingly out of nowhere, a massive crater appeared in one of the planet's most inhospitable lands. Early estimates said the crater, nestled in a land called "the ends of the Earth" where temperatures can sink far below zero, yawned nearly 100 feet in diameter. The saga deepened. The Siberian crater wasn't alone. There were two more, ratcheting up the tension in a drama that hit its climax as a probable explanation surfaced. Global warming had thawed the permafrost, which had caused methane trapped inside the icy ground to explode.
Now, however, researchers fear there are more craters than anyone knew — and the repercussions could be huge. Russian scientists have now spotted a total of seven craters, five of which are in the Yamal Peninsula. Two of those holes have since turned into lakes. And one giant crater is rimmed by a ring of at least 20 mini-craters, the Siberian Times reported.

It doesn't usually work that way. If it did, we'd have far more fires and explosions in homes that heat with gas.
When gas leaks, the vast majority of the gassed area has too high concentration of gas, and too low concentration of oxygen, to burn. Further out, it's too much air and too little gas. It is only at the "interface" between those two conditions that combustion is possible, and relatively speaking that's a miniscule volume compared to either the "air" volume or the "gas" volume at any given time.
In addition to that, if ignition does occur, usually only that small volume with the ideal mix burns, leaving (again) a volume of too-high concentration, and another too low. Explosions can alter that by chaotically mixing the gas with the surrounding air, and multiplying itself. But that seldom happens.
To sum it all up: gas fires and explosions are not very common, because conditions have to be nearly ideal at the precise spot where the ignition takes place. They happen on TV vastly more often than in real life.

The Great Extinction, caused by Siberia becoming one gigantic lava bed (probably after an asteroid strike), was a bit further back in time. Geologically, Siberia is old. You might be confusing the vestiges of Ice Age dessication (which was 10,000 years ago) but which involves the organics on the surface with the geology (aka rocks).
Regardless, though, of how the craters are forming, the fact remains that an awful lot of greenhouse gas is being pumped into the air, an awful lot of information on early civili

Ice expands as it freezes. We also know water under pressure will super cool and not freeze but it will still expand. Take a pop bottle and fill it with water without putting the cap on and set it in the freezer. It will spill out the top. Put the cap on it and it will simple expand the plastic bottle (or break a glass bottle)
Now imagine a hole in the ground or a pocket of water just under the surface of the ground. It freezes, pushes up, and brings the ground with it a bit. It's under pressure so it doesn'

You need to find out about methane clathrates. They are very roughly a chemical compound of methane and water which is solid and stable at low temperatures and moderately high pressures (as found under a few hundred meters of water or ice, for instance. When they get a bit too warm, or the pressure drops a bit they turn back into methane gas and water. One cubic meter of clathrate released almost 200 cubic meters of methane gas, which then has to go somewhere producing something like an explosion. At no point did the methane burn (it was nowhere near any free oxygen until it got to the surface, it was just a gas pressure explosion.

Re:Help me out here (Score:5, Informative)
I think the idea is this:
You have a large volume of clathrates underneath ice or frozen soil.
As things warm, they start to break down and a reservoir of methane gas builds up
at high pressure.
Eventually the pressure reaches the point where it can push aside or lift up or whatever the ice at its weakest point
and it finds a route to the surface.
Now you have a LOT of gas rushing through some kind of hole, a little bit like an oil well blowout and the gas flow erodes the sides of the hole and throws soil or ice into the air and generally starts to make a crater.
Furthermore the escape of all this gas lowers the pressure down where the clathrates are quite suddenly, so the breakdown accelerated greatly, providing still more gas to ruch up through the hole.
So not really an explosion, perhaps more like a blowout, but still fairly violent simply because of the amount of gas and the pressure.
At no point does it combust.

There is limited evidence of combustion. You can have an explosion from rapidly expanding gases without any sort of ignition. Some reindeer herders supposedly saw 'flashes' but it is certainly unclear if these were due to a methane ignition, the aurora borealis or just too much fermented lichen.

It never combusted. The permafrost melted and it all just went in the atmosphere and the loss of mass caused a sinkhole. The summary is bad. There was never a explosion besides the dust settling.
You're right, the summary could have been better, however I can say in its defence that the summary as you read it now is an awful lot better than the one I submitted.
It's quite a reasonable assumption that combustion is involved when coming across a discussion about a methane explosion, however in this situation there was no actual combustion. Despite this, the event was still quite accurately described as a methane exploding. Is there a common method of differentiating the two other than affixing a discla

Yes, if there had been a large explosion, even if it was not combustion, that amount of earth moving would have been measurable by seismic instruments thousands of miles away. Quarry explosions have been known to display as earthquakes as large as 2.7 on the Richter scale and felt for hundreds of miles, and those would pale in comparison to the amount of earth movement involved in the Siberian craters. It is much more likely that they escaping gas just gradually caused sinkholes, which would still create seismic events, but would be more likely many smaller ones and probably would not pick up on instruments unless they were within 100 miles.
