A coal seam approximately 30 meters under Australia’s Mount Wingen has been burning continuously for approximately 6,000 years, earning the place its famous nickname, Burning Mountain.
Underground coal seam fires are not at all uncommon, in fact it’s estimated that about 1,000 coal seams are burning around the world at any one point. Such fires usually occur in coal-rich but less-developed countries, and are usually put out in a matter of days, a month at most. That’s not always the case though, and India’s Jharia coalfield, which has been burning continuously for over 100 years, is a perfect example. But even this century-old fire pales in comparison with the world’s oldest coal fire, an underground coal seem that has been smoldering for about six millennia.
