The Ever-Burning Pit of Darvaza, Turkmenistan

Origins, Mysteries, and Tourist Impact

The “Ever-Burning Pit” of Darvaza, also called the Door to Hell, is a massive natural gas crater in Turkmenistan’s Karakum Desert that has been burning continuously for over 50 years. Created when a Soviet drilling rig collapsed in 1971, the site was set alight to prevent the spread of methane gas, but the fire has never gone out. Today, its blazing orange flames and eerie glow draw both scientists and curious travelers from around the world.

Standing at the edge of the crater, visitors witness a rare, raw display of geological activity and human intervention. The pit’s intense heat and otherworldly appearance make it one of Central Asia’s most unusual and memorable sights.

The Darvaza Gas Crater is not only a striking reminder of the region’s rich natural resources but also a potent symbol of the unexpected consequences of energy exploration.

History of the “Ever-Burning Pit”

The Darvaza gas crater, also known as the “Door to Hell,” has a documented history shaped by exploration, engineering setbacks, and the unpredictability of natural gas. Its origins trace back to Soviet-era scientific ambitions and the unintended consequences of 20th-century drilling practices.

Discovery and Early Exploration

Soviet geologists began surveying the Karakum Desert for natural gas reserves in the late 1960s. The region showed significant promise due to its vast hydrocarbon resources, attracting attention from energy experts.

Exploratory drilling operations identified an area near Darvaza with a substantial pocket of natural gas. Initial assessments revealed the ground’s instability, with signs of potential subsidence. Workers observed loose, sandy soil and unstable earth around the drill sites.

Despite these challenges, the Soviet teams continued their geologic surveys and drilling attempts. Their main objective was to boost gas production in Turkmenistan, which was a strategic location for the USSR’s energy needs at the time.

Soviet Gas Drilling Accident

In 1971, a drilling rig punctured a cavern filled with gas beneath the desert surface. The weight of the equipment triggered the ground to collapse, creating a large crater. The sudden release of natural gas posed both environmental and safety risks, threatening local wildlife and the surrounding area.

Soviet engineers made the decision to ignite the escaping gas, expecting the reserves to burn out within a few days. This effort aimed to prevent the spread of methane—a dangerous greenhouse gas—and reduce the risk of poisoning or explosions. However, the geologists underestimated the volume of gas below.

Instead of extinguishing in days, the fire has continued for decades, fueled by the vast quantities of natural gas still seeping from the underground deposits. The Darvaza gas crater remains a striking example of an industrial accident transformed into a geological phenomenon.

The site has since evolved from an isolated industrial mishap into a unique landmark visited by tourists, scientists, and journalists. The continuous blaze stands as a testament to both human error and the challenges inherent in energy extraction.

Geological Formation and Structure

Darvaza’s “Ever-Burning Pit” is both a dramatic geological landmark and a window into the processes that formed it. Its structure, origins, and the natural gas underlying the region are critical in understanding why the crater continues to burn decades after its creation.

Geological Origins

The site where the Darvaza crater sits is part of the Karakum Desert, a vast area with significant oil and natural gas reserves. In 1971, Soviet geologists were drilling for gas when the ground beneath their rig collapsed, creating a large sinkhole.

They decided to ignite the escaping gas to prevent the spread of toxic methane. The engineers expected it to burn off in a few days, but the fire continues to burn, fueled by the steady release of natural gas. The incident was not a unique geological phenomenon, but the combination of soft surface materials and a gas pocket near the surface made the collapse especially dramatic.

Nearby, similar sites have been mapped, but none have formed craters of this scale or burn for as long. Ongoing erosion and the composition of the ground at Darvaza—mainly sand and clay—contributed to the size and shape of the depression.

Physical Characteristics of the Crater

The Darvaza crater measures about 70 meters (230 feet) in diameter and roughly 30 meters (98 feet) deep. Its circular shape is a result of the abrupt ground collapse caused by the drilling accident.

The walls of the crater are sheer, with exposed layers of compacted sand and clay, visibly scorched by continuous combustion. Temperatures near the pit’s edge can become extremely high, and the area around the crater shows evidence of heat-altered minerals.

Inside the crater, dozens of visible gas vents feed constant flames and flickers of fire. At night, the glowing pit is visible from several kilometers away, giving the impression of a burning furnace.

Natural Gas Deposits Beneath Darvaza

The region around Darvaza sits atop one of Central Asia’s largest natural gas fields. Methane is the primary component of the gas seeping into the crater, and it escapes under pressure from underlying reservoirs.

Gas escapes through porous layers of earth and fractures in sedimentary rock. This release of methane was accelerated by the original drilling operation, which punctured a gas pocket close to the surface.

A simple overview of the subsurface structure:

Layer Composition Significance Surface Sand, clay Susceptible to collapse Shallow subsurface Looser sediments Allows gas migration Deeper reserves Methane-rich gas Source of ongoing fire

The gas is both the reason for the crater’s existence and the source of the long-lived fire, with the flow rates still sufficient to support continuous combustion decades later.

How the Darvaza Gas Crater Burns Continuously

The Darvaza gas crater remains alight due to a unique combination of geology, natural gas supply, and ignition circumstances. Continuous high temperatures and ongoing gas emissions have created a stark environment that has drawn interest from scientists and travelers.

Mechanism of Persistent Combustion

The pit formed in 1971 when a Soviet drilling operation accidentally collapsed an underground cavern, releasing large quantities of natural gas. In an attempt to control the spread of methane, geologists set the gas alight, expecting it to burn off within a few days.

However, the subsurface holds a vast supply of hydrocarbons. Methane, the main component, escapes steadily from cracks and vents along the bottom and sides of the crater. This constant gas flow feeds the flames with a sustained fuel source.

Open air and wind play a role by allowing oxygen to mix thoroughly with the rising gas. This mixture sustains surface combustion and ensures the flames remain visible. The pit's exposed location makes it easy for new gas to reach the surface as older reserves are depleted.

Temperature and Emissions

Temperatures within the crater can reach upwards of 1,000°C (1,832°F) near the flame zones. The intense heat keeps the pit’s surface scorched and barren, inhibiting any plant growth within its immediate vicinity.

The combustion process predominantly releases carbon dioxide (CO₂), water vapor, and nitrogen oxides. Methane is also released in smaller quantities when leaks occur around edges where combustion is incomplete.

Below is a summary of key emissions:

Gas Emitted Source Environmental Impact Carbon Dioxide Complete combustion Contributes to greenhouse gases Methane Incomplete burns Potent greenhouse gas Nitrogen Oxides High temps & air Causes air pollution

Local air quality is notably affected by these emissions, especially on days with little wind. The combination of high temperatures and gas output shapes the environment around the crater.
