The Underground Fires That Can Burn for Centuries | Full Documentary

A fire can burn without flames.

Deep beneath the ground, coal seams can smolder for decades or even centuries, consuming ancient fuel while the surface above appears almost normal.

In The Underground Fires That Can Burn for Centuries, we explore how these hidden fires begin, why they are so difficult to extinguish, and how they can transform the landscape above them.

Some underground fires begin naturally, while others are caused by mining, exposed coal seams, lightning, or human activity.

Once a fire enters a coal seam, the ground itself becomes fuel. Oxygen travels through cracks and openings, heat spreads through the surrounding rock, and combustion slowly advances through the underground deposit.

Unlike a surface fire, an underground coal fire can survive for generations because the fuel source may stretch for miles.

The consequences can be dramatic.

Ground above the burning seam can collapse. Roads and buildings can become unstable. Smoke and gases can escape through cracks, vegetation can die from extreme heat, and groundwater can be affected.

Engineers may try to stop these fires by sealing oxygen pathways, excavating burning material, or flooding and cooling the affected area. But locating the fire underground can be incredibly difficult.

The most remarkable part is the timescale.

A fire can disappear from view without actually disappearing.

It can smolder beneath the earth, slowly consume a coal seam, and continue burning long after the people who witnessed its beginning are gone.

The Underground Fires That Can Burn for Centuries.

A journey beneath the surface to uncover one of Earth's strangest and longest-lasting fires.
