Vice Australia:

A coal mine is currently burning the hell up in Australia. For obvious reasons fires in coal mines are especially problematic—the exposed coal face burns, just like coal should, and smoulders through the underground seam where it’s safely protected from any firefighting. if you find yourself in Australia, avoid Morwell. It’s just not a healthy town.

Brings to mind the (still – since 1962) burning coal mine in the now mostly abandoned town of Centralia, Pennsylvania.
