That sounds to me like it's a coal seam that is on fire. It does remind me of Centralia, Pa. when that started back in the 1960s or so. This fire in
Pennsylvania was releasing so much chemicals into the air, the government had no choice but to relocate Centralia. Mine/coal seam fires can burn for
decades if left unchecked. I do not really know of how many possible coal seam fires that I have heard about over the years. Centralia is certainly
one of the most famous, if not the most famous case of a coal seam fire.
Being from West Virginia, we know what fires like that can do to the environment. We've had a couple mine fires down here that have been burning
since the late 1960s in underground mines. As for how to fight them, it's not a s simple as most people would think. First you would need to find the
closest entrance to the fire. Then you have to go around and fill in every single nook and crany so that no oxygen can get to the fire to fuel it.
At least we hope it is a coal fire and not something more destructive and deadly.
