Darvaza gas crater
The Darvaza gas crater (Turkmen: Garagum ýalkymy), also known as the Door to Hell or Gates of Hell, is a burning natural gas field collapsed into a cavern near Darvaza, Turkmenistan. How the crater formed and ignited remains unknown.
The early years of the crater's history are uncertain. Relevant records are either absent from the archives or classified or inaccessible. Some local geologists have claimed that the collapse into a crater happened in the 1960s; it was set on fire only in the 1980s to prevent emission of poisonous gases. Others assert that the site was drilled by Soviet engineers in 1971 as an oil-field but collapsed within days, forming the crater; the engineers chose to flare the crater to prevent emission of poisonous gases but underestimated the volume of the gas.Controlling the burn
In April 2010, President Gurbanguly Berdimuhamedow recommended that measures be taken to limit the crater's influence on the development of other natural gas fields in the area. In January 2022, Berdimuhamedov announced plans to extinguish the crater in light of its negative effects on the environment and public health; a commission was established to find the optimum technique.
