Template:Main otherScript error: No such module "Infobox".Template:Template otherScript error: No such module "Check for unknown parameters".Script error: No such module "Check for clobbered parameters".Template:Main other Yanar Dagh (Template:Langx, Template:Lit) is a natural gas fire that burns perpetually on a hillside on the Absheron Peninsula near Baku, the capital of Azerbaijan, a country known as "the Land of Fire". Flames rise up to Template:Convert from a thin, porous layer of sandstone.[1][2]
The Yanar Dagh flame burns steadily, fueled by a continuous seep of gas from beneath the surface. Unlike the nearby mud volcanoes of Lokbatan or Gobustan, there is no mud or liquid discharge at Yanar Dagh.[3]
Administratively, Yanar Dagh is part of the Absheron District of Azerbaijan. The State Historical-Cultural and Natural Reserve was established on the site by presidential decree on May 2, 2007, and is managed by the State Tourism Agency of the Republic of Azerbaijan. Following a major renovation between 2017 and 2019, the Yanar Dagh Museum and the Cromlech Stone Exhibition were opened within the Reserve.[4][5]
History
Since the first millennium BCE, the fire served as a link between humans and supernatural powers in the Zoroastrian religion.[6]
The high concentration of natural gas beneath the Absheron Peninsula has sustained natural flames throughout history, which were documented by historical figures such as Marco Polo.[1] Once common in Azerbaijan, only a few natural fires remain today, with Yanar Dag being the most notable example.[6]
Besides Yanar Dagh, the most well-known site of a similar natural fire is the Fire Temple near Baku, located on the outskirts of the Greater Caucasus. This religious site, known as an Ateshgah, meaning "temple of fire", holds historical significance in fire-worship traditions.[7] Similar to the flames of Yanar Dagh, the fire at the Ateshgah of Baku was originally a natural phenomenon resulting from the seepage of natural gas through porous strata. However, the natural gas flow at Ateshgah ceased some time ago, and the flames now visible there are sustained by a gas main, while the flames at Yanar Dagh continue to burn naturally.[6]
According to local accounts, the Yanar Dagh flame was only discovered in the 1950s when it was accidentally ignited by a shepherd.[3]
Natural gas fires
The Yanar Dagh fires are caused by the emission of hydrocarbon gases from subsurface layers of the Earth.[8][9][6][10]
The flames emanate from vents in sandstone formations, reaching heights of up to Template:Convert at the base of a Template:Convert scarp below a hillside, although other sources cite varying figures.[1][8] Yanar Dagh is described by the Geological Survey of Azerbaijan as "Intensive flames, to Template:Convert high, develop for Template:Convert along the base of a Template:Convert and Template:Convert tectonic scarp."[9] It has also been suggested that such fires may contribute to thermal metamorphism.[11]
A study conducted by geologists from the Geological Survey of Azerbaijan analyzed four samples collected from Yanar Dagh. The results revealed that the area of maximum flux was located at the upper side of the fault scarp, precisely where the flames originate. The value of microseepage recorded was in the range of 103 mg m−2 d−1 at approximately 30 metres (~100 ft) from the fire, on the upper part of the study area. It has been inferred that the degassing area extends beyond the measured zone, with microseepage likely occurring pervasively along the fault line. This fault scarp is believed to be part of the extensive Balakhany-Fatmai structural formation on the Absheron Peninsula.[9]
State reserve
In order to protect this landmark and boost tourism in the region, the Yanardagh State Historical, Cultural, and Natural Reserve was established by presidential decree on May 2, 2007. Operating under the State Tourism Agency, the reserve is located in the village of Mammadli. Following extensive renovations between 2017 and 2019, the Yanardagh Museum and Yanardagh Cromlech Stone Exhibition were opened within the reserve. Spanning 64.55 hectares, the site includes a 500-seat amphitheater for outdoor concerts. The reserve also features a three-zone museum showcasing ancient stones and local craftsmanship, along with tombstones, ancient kurgans, and two burial grounds containing historic graves.[4][5][12]
