5 Places That Are Still On Fire

Living near an active volcano can make you nervous, but it's not the only fire down below. Coal is a long-burning mineral hidden underground that can ignite when the circumstances are right. Those circumstances include contact with air, which happens when we try to take the coal out of the ground for our own purposes. Here are five coal seams that have been burning for a long time.

1. Brennender Berg, Germany

Brennender Berg in English is "Burning Mountain," although it is more of a gorge than a mountain. It refers to an area of Germany between the towns of Dudweiler and Sulzbach-Neuweiler, under which a seam of coal has been burning for over 300 years. The tale is told of a shepherd who started a wood fire on a tree stump in 1688 which burned to the roots and ignited the coal seam, but it was most likely a case of spontaneous combustion. The burning coal seam is now evidenced by glowing embers and sulfurous smoke, rather than flames as in the past. The area is not as dangerous as it was in previous centuries, and is open for visitors. A hike is recommended for days after a rain.

2. Smoking Hills, Canada

The Smoking Hills of Canada are located near Franklin Bay on the Arctic Ocean in the Northwest Territories of Canada. The uninhabited hills (the nearest community is about 65 miles away) are above the Arctic Circle. Discovered in 1826 by explorer John Franklin, the hills are notable for exuding constant smoke from burning coal underground. The mountains contain large deposits of lignite (brown coal), sulphur, and oil shales. A reaction between sulphur and lignite leads to spontaneous combustion, and it is believed that the lignite has been burning for hundreds of years. The smoke coming from the coal seams is highly acidic, and the lakes surrounding the Smoking Hills are polluted with sulphur dioxide, habitable only by species that thrive in acid environments. In 1850, Robert McClure's expedition into the Northwest territory took them to the Smoking Hills. They collected a specimen of the burning minerals, which burned a hole through the captain's mahogany desk. The various chemicals in the burning rock and smoke have left bright stripes of color along the hills. 

3. Burning Mountain, Australia

Burning Mountain is officially named Mount Wingen, 139 miles north of Sydney, Australia. It is part of the Burning Mountain Nature Reserve. The mountain was first thought to be a volcano because of the vents spewing sulfurous smoke, but later investigation proved it to have a burning coal seam running underneath. The traditional story told by the Wannarua people tells of a Wonnarua woman whose husband did not come home from a battle. She climbed the mountain and wanted to die, but instead turned into a stone that cried tears of fire. The burning tears rolled down the mountain and set it on fire. Modern theories say the fire started by either lightning strike or by spontaneous combustion. The coal seam is two meters thick and 20-30 meters below the surface. Estimates of how long it has been burning range from 5,000 to 15,000 years!

4. Centralia, Pennsylvania, USA

Coal-rich Pennsylvania has endured plenty of coal seam fires, but most eventually are extinguished or burn themselves out. Not so in the town of Centralia. Deep mining left passageways underground as strip mining tore up the surface. As the coal played out, pits were left behind. The town of Centralia wanted to clean up a mining pit turned landfill to make room for more garbage. Volunteer firefighters ignited a fire to clean it out on May 27, 1962. The fire was doused with water that night, but was found to be burning the next day. More attempts to put the fire out were unsuccessful, and it was discovered that a hole in the pit led to a mine passage. That started the fire down a coal seam, which stymied all attempts to extinguish it. However, others theorize that the coal seam fire already existed before the landfill burning. At any rate, the fire continued for years, long after the town ran out of money to fight it. The underground fire reached downtown by 1979, when a gas station owner (who was also the mayor) measured his gasoline storage tank at 172 degrees! In 1981, a 12-year-old boy fell into a sinkhole, releasing steam and carbon dioxide (he was pulled out by his cousin and survived). The citizens of Centralia abandoned the the unsafe town, accepting government buyouts on their property offered in 1984. The nearby town of Byrnesville was also abandoned because of the underground fire. Centralia was officially condemned in 1992, but a very few residents refused to leave. The 2010 census listed the population of Centralia at ten people. The fire has now been burning for over 50 years

5. eMalahleni, South Africa

Coal mining in the Mpumalanga province (formerly East Transvaal) of South Africa centers around the city of eMalahleni, which means "place of coal." It was formerly known under its Afrikaans name, Witbank. The extensive Transvaal and Delagoa Bay Collieries were abandoned in 1953 without reclamation, and parts of the mines have been on fire ever since. Witbank coalfield mines typically had a low coal recovery ratio, and the pillars of coal left behind spontaneously combusted in contact with oxygen. The abandoned underground mine passages collapse unexpectedly, and have injured and killed people occasionally over the years, either from the collapse or the burning coal underneath. 

These are not the only long-burning coal seam fires. They've happened throughout history, and sometimes burn for centuries. There are other underground coal fires burning today as well, all over the world.
