Subterranean collapse - probably caused by underground water.

Doesn't explain the crater walls around it - whatever created it, involved a fairly explosive event. Be it impact from above or explosive from below, it pushed a lot of material up and outwards

[Eric Mc]

Didn't notice that.

Methane explosion?

There is quite a bit of methane bubbling out under Siberia.

[Simpo Two]

I don't see how methane could explode underground, there's no ignition source.

Can't tell from the video of the hole is full of water or just a hole...

[FatSumo]

The loons have already jumped onto it, 'Global warming that done it!'



Better add it to the list

Some of the pics do make it look like a photshop on a nimbus, but it's really real.
