Approximately 224 km north of Sydney, just off the New England Highway, in New South Wales, Australia, is a hill that has been burning for the last 6,000 years. The fire burns underground, at a depth of about 30 meters, fueled by a coal seam that runs through the sandstone. The aborigines called the mountain Wingen, which means ‘fire’, and used its heat for warmth in the winter months, for cooking and for the manufacture of tools. They believed that the mountain was set on fire by a tribesman to warn others when the Devil carried him off deep into the earth. European explorers and early settlers knew of the Burning Mountain but they thought the smoke coming out of the ground was volcanic in origin. It was not until 1829 that a geologist identified it as a coal seam fire.

Coal seam fire, as it happens, are incredibly common, and thousands of them are burning underground across the world. In the US state of Pennsylvania alone, as many as 45 fires are burning, the most famous being the Centralia mine fire which has been burning since 1962. In India, more than seventy individual fires are burning beneath a region of the Jharia coalfield in Jharkhand. The fires, which started in 1916, are rapidly destroying the only source of prime coking coal in the country. The problem is more acute in coal-rich nations such as China, where underground fires are consuming at least 10 million tons of coal annually—with some estimate putting the figure to twenty times more. Beside losses from burned and inaccessible coal, these fires contribute significantly to air pollution and increased levels of greenhouse gases in the atmosphere. A geologist from the University of Alaska at Fairbanks calls them “a worldwide catastrophe with no geographic territory, and if we don’t take care of them they’re going to take a toll on us.”
Underground coal-seam fires are the most persistent fires on Earth and can burn for thousands of years. There is geological evidence that coal seam fires existed as early as the Pleistocene era, although modern-day coal fires are usually the result of human undoing, such as mining accidents or open coal seams unintentionally coming in contact with oxygen. Some coals ignite spontaneously at temperatures as low as 40 °C. Once fire gets hold, temperatures climb rapidly. The permeability of the coal allows oxygen to reach the fire but poor ventilation traps the heat inside. Some coal fires exceed temperatures of 500 °C.
Coal fires are very difficult to extinguish. It’s like a frustrating, expensive version of whack-a-mole, writes Dan Cray for Time. “You put one down, then 300 feet later another one picks up,” says Mark Engle, a geologist with the U.S. Geological Survey. Many governments have completely given up on the effort.
One of the most visible changes coal seam fires make is upon the landscape and on the environment. For example, near a coal fire in Germany, elevated ground temperatures allowed many insects and spiders to survive the cold winter. In Australia’s Burning Mountain, the heat has killed off all vegetationexcept those in the periphery of the burning seam, which actually thrives from run-off from the brunt soil. Large areas of the land has collapsed as a result of the burnt-out coal seam, and smoke vent from many cracks on the ground. The heat has turned the soil red.
Unlike Pennsylvania’s Centralia, Burning Mountain is actually pretty safe for tourists. There is a 4 km-long walking trail through the region with information panels along the track unpacking the story of Burning Mountain and the fascinating Aboriginal heritage. A viewing platform at the climax of Burning Mountain walk provides a safe vantage point to view the exhaust vents and rocks transformed by extreme temperatures.

Almost every medal that is there to be taken is in her kitty but M C Mary Kom says she still trains like a maniac, the latest result of the regimen being a gold on debut at the Commonwealth Games in Gold Coast on Saturday.
The 35-year-old mother-of-three, who has five world titles and an Olympic bronze medal, is seen as a sporting icon not just in India but also in other countries.
Crowned Asian champion just months ago, Mary Kom added the light flyweight (48kg) Commonwealth crown to her tally.
“The secret to my success is my fitness and I am very quick. I plan well before bouts. I am lucky that I can catch my opponents within seconds, I am able to read them very quickly,” a giggling Mary Kom said at the end of her CWG campaign.
“I don’t have injuries, all I have is minor issues like cramps sometime,” she added.
And the secret to her fitness levels and to an extent her calm demeanour in the ring is a training regimen that she refuses to let go even one day.
“When I decide something with my head and heart than even my husband cannot stop me. He sometimes tells me to take it easy after competition but I can’t help it,” she said.
“I have to train to keep myself calm. It’s a a strong urge, it’s a habit and training makes me happy. When I don’t train I feel sick sometimes,” she added.
But despite the high fitness levels, she wouldn’t commit on whether the outlandish possibility of a 2020 Olympic appearance is on her mind.
“2020 is difficult to say, but I will try my best. 48kg is not there and I will have to put on weight to be in 51kg which is never easy. If I am super fit till 2020, I will compete but if I am not fit I will not,” said the accomplished boxer.
Elated at being India’s first woman boxer to claim a Commonwealth Games gold, Mary Kom said scripting history makes her happy.
“I have won everything and all of my medals are very important. Do I need to say more? Which other boxer can claim that, now I would not be scared of anyone. I am very happy that I created history. I have got everything,” she said.
“I still think about Olympics gold but other than that I have got everything. Even in Olympics, I do have a medal. I haven’t left out anything,” she signed off.
