Why Turkmenistan’s ‘Door to Hell’ Has Been Burning for 50 Years

In the emptiness of Turkmenistan’s Karakum Desert, a fiery pit has blazed for more than half a century. Officially known as the Darvaza Gas Crater, the site’s burning flames and glowing walls have earned it the evocative nickname the Door to Hell. What began as a mining mishap in the early 1970s has become one of the most enduring unintended fires on the planet, and experts say there is no easy way to put it out.

The crater, roughly 230 feet (70 meters) wide and 100 feet (30 meters) deep, lies near the village of Darvaza in north-central Turkmenistan. It was created in 1971 when Soviet gas explorers drilled into what they hoped was a conventional reserve. Instead, the ground beneath the rig collapsed into a cavern filled with methane-rich natural gas. As vents opened, methane and other gases began rising to the surface.

To prevent toxic gas from leaking into the surrounding environment, engineers set it on fire, expecting the flames to consume the fuel within days or weeks. “Soviet scientists set the crater ablaze, thinking the fire would die down within a few weeks,” according to Live Science. Fifty-three years later, the crater still burns.

A Geological Match That Won’t Quit

The reason the fire persists is not supernatural, but geological. The Karakum Desert lies within the Amu-Darya Basin, one of the world’s richest oil and natural gas provinces. Vast amounts of methane seep through porous rock beneath the desert. When the drilling accident opened a direct path to those reserves, it effectively created a funnel that continuously feeds fuel to the flames.

As Mark Ireland, an energy geoscientist at Newcastle University, told National Geographic: “We shouldn’t be surprised it exists.”

Methane is a highly flammable gas. Once it mixes with oxygen at the surface and finds an ignition source, combustion continues as long as there is fuel, oxygen, and heat present, the exact conditions that have persisted at Darvaza for decades.

Why Stopping It Is So Hard

Experts say the fire does not behave like a typical wildfire that eventually exhausts its fuel. Rather, it resembles a furnace attached to a massive underground pipeline. As long as the subterranean reserves continue to seep methane through cracks and fissures, there is no simple way to stop the blaze.

Several ideas have been discussed over the years, from drilling relief wells to siphon off pressure, to filling the crater with soil or fire-retardant materials, but each comes with serious challenges. The heat around the crater rim can be extreme, and the unstable ground makes close work hazardous.

The Turkmen government has periodically raised the idea of quenching the flames. In 2010, then-President Gurbanguly Berdimuhamedow ordered officials to find a way to extinguish it, citing environmental concerns and the loss of valuable gas resources. However, no permanent solution was found, and the fire continued.

An Icon Born From Miscalculation

Over time, the crater’s continuous blaze has become a global curiosity and a symbol of unintended consequences. The official name for the site in Turkmenistan is the “Shining of Karakum,” but its fiery appearance and eerie glow at night quickly earned it the more ominous labels “Door to Hell” and “Gates of Hell.” Tourists now make the journey into the desert to see the flames, which illuminate campsites and draw photographers from around the world.

Environmental scientists point out that the blaze is not just a spectacle. Methane itself is a powerful greenhouse gas, far more effective at trapping heat than carbon dioxide in the short term. Burning it converts methane into carbon dioxide and water vapor, which still contribute to warming but are less potent than methane alone.

Still, the crater emits significant quantities of carbon dioxide year after year, representing both a waste of combustible fuel and an ongoing source of emissions. Some researchers estimate that the crater consumes thousands of cubic meters of natural gas every day, fuel that could otherwise have economic value or be used for energy production.

What the Future Holds

Despite occasional talk of closing or filling in the crater, engineers warn there is no clear, practical way to do so without risking new leaks or even explosions. The geology that feeds the fire is unpredictable and complex, and any attempt to seal the pit would require drilling and construction under extreme conditions that might simply divert the methane to a new outlet.

Whether the crater continues burning for another decade or a century, its fate is tied to the unseen dynamics beneath the desert sands. For now, the Door to Hell remains exactly that, a monument to human miscalculation, the power of subterranean forces, and the intractable challenges of stopping a flame born from the Earth’s own fuel.
