Turkmenistan’s “Gates to Hell” Shows Marked Decline in Flame Intensity

Infrared imaging collected in 2026 indicates that the fire burning within the Darvaza crater has lost more than three-quarters of its heat output over the preceding three years. The analysis, performed by Capterio—a firm that monitors natural-gas flares—shows a reduction of over 75 percent in thermal intensity, suggesting that the long-standing blaze is waning significantly.

The Darvaza crater, popularly called the “Gates to Hell,” is a natural-gas sink the size of a soccer field located in Turkmenistan’s desert interior. The site has burned continuously for decades, becoming a distinctive tourist attraction and even appearing in a self-promotional video produced by a Turkmen president. Its persistent flames have made it a focal point of both curiosity and environmental concern.

Capterio’s infrared data, captured this year, quantifies the decline: heat emissions have fallen by more than 75 percent since 2023. The company’s methodology involves satellite-based thermal imaging that tracks the intensity of gas flares worldwide. The reported decrease is consistent across multiple observations, confirming a sustained dimming rather than a temporary fluctuation.

Turkmenistan’s authorities have long pledged to extinguish the crater’s fire, citing environmental damage and adverse health effects on nearby populations. In recent statements, officials credited the drilling of adjacent gas wells in 2024 with accelerating the reduction in flame intensity. The government frames the dimming as a positive step toward mitigating the ecological and public-health risks associated with the uncontrolled combustion.

While the government attributes the recent decline to the 2024 wells, Capterio’s data suggests that the heat reduction began earlier than that year. This discrepancy introduces uncertainty about the precise cause of the dimming. The independent analysis indicates that the fire’s intensity started to fall before the newly drilled wells could have exerted influence, leaving the underlying mechanism unresolved.

If the fire continues to weaken, the environmental and health concerns cited by Turkmen officials may diminish, potentially reducing local air-quality impacts. Conversely, the crater’s status as a unique tourist destination could be affected, altering visitor numbers and related economic activity. The government has not announced a definitive plan for fully extinguishing the blaze, and further monitoring by firms like Capterio will be essential to track the crater’s evolution in the coming years.
