[SWR] Is this hole that appeared in Siberia a sinkhole or a blowout
It looks like a sinkhole or some kind of collapse from the air. However, an oblique view looks like there is elevation along the sides, which would imply an explosion.

The earth scattered around the edges of the hole would seem to me to indicate that it’s not a just a collapse (large hole, not that much debris…) but did “explode” too.

Re: [SWR] Is this hole that appeared in Siberia a sinkhole or a blowout
In all seriousness. If it were a meteor strike, or something did blow up, within the last ? years, wouldn't it have registered as a seismic event? The place for that is in Boulder CO, and they can pick up stuff from all over the world. That's partially I think how they measure wether someone has set off an underground nuc. Carl….

Re: [SWR] Is this hole that appeared in Siberia a sinkhole or a blowout
Given the presence of both thermogenic and biogenic gas in the subsurface in that area, I'd hazard a guess that the feature is a methane hydrate blowout and collapse feature developed in the permafrost. These seepages will most likely be occurring more often as the Arctic areas of the world become increasingly warmer. Methane hydrates in permafrost areas represent a very large volume of reservoired methane that is kept in a solid state by the relatively constant temperatures of the permafrost. Warm them up, however, and the hydrates quickly change to a gas phase with an approximate 170X volume increase.
