The commonly repeated origin story holds that Soviet geologists, drilling for natural gas in Turkmenistan's Karakum Desert around 1971, struck an underground cavern and the drilling rig collapsed into it, opening a crater roughly 70 metres wide and 20 to 30 metres deep. Concerned about methane gas endangering the small nearby village of Derweze (from which the crater takes its name β darvaza means "gate" in Turkmen), geologists reportedly ignited the escaping gas, expecting it to burn off within a few weeks.
More than five decades later, it was still burning β a discrepancy between the tidy origin story and the fire's genuinely surprising longevity that some researchers now treat with appropriate scepticism, since no definitive Soviet-era documentation of the exact incident, date, or original rationale has ever been publicly produced. What's certain is the crater's existence, its early-1970s dating, and the sheer scale of gas reserves beneath it β confirmed by a 2013 National Geographic-led expedition, whose findings suggested the crater could theoretically burn for centuries if left entirely undisturbed.
