According to the episode there were at one time structures in Siberia which have a dome-like shape to them and have been described as "cauldrons." People have come down with strange illnesses when spending time near them and recover when they leave. It's theorized that it's a defense system of some kind. Either from space objects or opposing aliens. At present they are sunken into the ground.
Maybe this is crazy but is it possible that that blast up there was designed to get rid of those structures? Having never heard of any structures being there, that's the first thing to pop into my head.
