Scientists estimate that Australia's BurningMountain, the oldest known coal fire, has burned for 6,000 years. In the 19th century, explorers mistook the smoking summit for a volcano.
Over 5500 years ago a coal seam beneath the exterior of Australia's Burning Mountain ignited 90 feet below the surface making it the longest known continuous fire on the planet.
A coal seam-fueled eternal flame in Australia known as "Burning Mountain" is claimed to be the world's longest burning fire, at 6,000 years old. A coal mine fire in Centralia, Pennsylvania, has been burning beneath the borough since 1962.
Know about the underground coal mine fire burning in Centralia, Pennsylvania, since 1962 and its dangerous impact on health and the environment.
The Centralia mine fire is a coal-seam fire that has been burning in the labyrinth of abandoned coal mines underneath the borough of Centralia, Pennsylvania, United States, since at least May 27, 1962. Its original cause and start date are still a matter of debate.
Yanartas. Turkey's Yanartaş (meaning "flaming stone") is an odd geographical site that features dozens of little fires caused by methane gas vents in a rocky mountainside. The fires have been burning for an estimated 2,500 years.
Nitrocellulose: a fire with no burns.
The Behram Fire at the Yazd Zoroastrian Fire Temple in Iran is thought to be the oldest human-made eternal flame, at more than 1,500 years old. It has been burning since 470 AD and can only be witnessed by practicing zoroastrians, who've tended to it over countless generations.
How did people make fire in the early Middle Ages (NL)? Two methods were used to make fire. One was by striking a special piece of iron (strike-a-light) on a piece of flint. The other method is by friction of wood on wood.
The oldest unequivocal evidence, found at Israel's Qesem Cave, dates back 300,000 to 400,000 years, associating the earliest control of fire with Homo sapiens and Neanderthals. Now, however, an international team of archaeologists has unearthed what appear to be traces of campfires that flickered 1 million years ago.
In eastern Australia, these three components have been going strong since prehistoric times, leading to the longest-lasting known fire in the world: a scorcher that has burned beneath Mount Wingen in New South Wales for at least 5,500 years — although some geologists suspect it could be up to 500,000 years old.
Lightning or a brush fire can also ignite soft coal. The fires burn downward, acquiring air through fissures in rock and microscopic spaces between grains of dirt. An underground fire may smolder for years, or even decades, without showing signs on the surface.
Highest temperature
Dicyanoacetylene, a compound of carbon and nitrogen with chemical formula C4N2 burns in oxygen with a bright blue-white flame at a temperature of 5,260 K (4,990 °C; 9,010 °F), and at up to 6,000 K (5,730 °C; 10,340 °F) in ozone.
The 1935 Big Scrub Fire in the Ocala National Forest was the fastest spreading fire in the history of the U.S., covering 35,000 acres in 4 hours. In 1956, the Buckhead Fire burned 100,000 acres in Osceola National Forest in a single day.
Burning Mountain is an iconic geological phenomenon in New South Wales, Australia. It is renowned for being the longest burning fire in the world, having been alight for more than 6,000 years!
The Chinchaga Fire started in logging slash in British Columbia, Canada, on 1 June 1950 that grew out of control and ended five months later on 31 October in Alberta; in that time, it burned approximately 1.2 million hectares (3 million acres) of boreal forest.
The first to propose such an early arrival for Aboriginal peoples was Gurdip Singh from the Australian National University, who found evidence in his pollen cores from Lake George indicating that Aboriginal people began burning in the lake catchment around 120,000 years ago.
Today, many scientists believe that the controlled use of fire was likely first achieved by an ancient human ancestor known as Homo erectus during the Early Stone Age.
If early humans controlled it, how did they start a fire? We do not have firm answers, but they may have used pieces of flint stones banged together to created sparks. They may have rubbed two sticks together generating enough heat to start a blaze. Conditions of these sticks had to be ideal for a fire.
It wasn't just humans who regularly used fire, says Filipe Natalio, an archeologist at the Weizmann Institute of Science in Israel. Neanderthals were likely just as advanced in using it to cook and make weapons, he says, with Neanderthals tending to their flames in Europe while modern humans cooked in Africa.
The main sources of ignition before humans appeared were lightning strikes. Our evidence of fire in the fossil record (in deep time, as we often refer to the long geological stretch of time before humans) is based mainly on the occurrence of charcoal.
Ancient neolithic settlements in Spain have produced evidence of humans creating fire through a variety of methods including friction with wood and kindling, stone and flint, and more.
This is black fire. When you mix a sodium street light or low-pressure sodium lamp with a flame, you'll see a dark flame thanks to the sodium and some excited electrons.
Cool flame can occur in hydrocarbons, alcohols, aldehydes, oils, acids, waxes, and even methane. The lowest temperature of a cool flame is poorly defined and is conventionally set as a temperature at which the flame can be detected by eye in a dark room (cool flames are hardly visible in daylight).
Cool flame, a flame having maximal temperature below about 400 °C (752 °F)
