It certainly looks obvious that something blew up from below, but
I'm not sure that the volume of ejecta is as large as the void below
appears. It would help to know more about the geology, hydrology, and
water-table level in the region (is the lake in the distance above or
below the bottom of the pit)? If warming-driven methane degassing can
cause an explosive event that large, that's scary. I'll be interested to
know what the Russians conclude from the promised investigation.
