Likely a cave system that collapsed?

One comment had been that as this is ~ 40 km from a large oil and gas field,
its quite possible that the crater is the result of an underground gas explosion.

Its not just a collapse as the video and other pics I have seen clearly show ejecta

cheers

Large crater in Siberia

My first thought was a lava dome because it looks so black down there. Judging by the streaks on the side of the shaft water has seeped in for some time, ...

Is the local geology there limestone , as around Patomskiy crater?
