Introduction
In the quiet district of Haripur, Bangladesh, lies a geological marvel known as Fire Mountain. Since 1955, this mountain has been ablaze, its flames refusing to die out. What began as a catastrophic gas explosion has transformed into a natural wonder, drawing scientists, tourists, and storytellers alike. The eternal flame of Haripur is not just a cultural landmark—it is a living laboratory of geology, chemistry, and environmental science.
This blog explores the scientific reasons behind the eternal flame, its global context, and why Haripur’s Fire Mountain continues to burn nearly 70 years later.
The Origin: The 1955 Gas Explosion
In 1955, Haripur experienced a massive natural gas eruption. The explosion ignited underground reserves, and the fire spread across fissures in the mountain. Unlike ordinary fires, which die out once fuel is exhausted, this blaze tapped into a continuous supply of methane and other hydrocarbons trapped beneath the earth’s crust.
The result? A flame that has burned uninterrupted for decades, earning the site its legendary name: Fire Mountain.
Scientific Explanation: Why the Flame Still Burns
- Natural Gas Reservoirs
- Haripur sits atop sedimentary rock formations rich in hydrocarbons.
- Methane (CH₄), the primary component of natural gas, seeps through cracks and ignites upon contact with oxygen.
- Because the reservoir is vast, the flame sustains itself without external intervention.
- Geological Fissures
- The explosion fractured the mountain, creating pathways for gas seepage.
- These fissures act like natural chimneys, channeling gas upward to feed the flame.
- Combustion Chemistry
- Methane combustion follows the reaction:
[ CH_4 + 2O_2 \rightarrow CO_2 + 2H_2O + \text{Heat} ] - The continuous release of heat ensures the flame remains visible, day and night.
- Comparison with Other Eternal Flames
Haripur’s Fire Mountain is part of a global phenomenon:
- Yanardag, Azerbaijan – Flames fueled by natural gas seepage.
- Chestnut Ridge, Pennsylvania (USA) – Eternal flame in a waterfall, sustained by methane leaks.
- Erta Ale, Ethiopia – Lava lake burning for over a century.
These examples show that Haripur’s flame is not supernatural but a natural geochemical process.
Environmental and Cultural Impact
Environmental Concerns
- Carbon Emissions: Continuous burning releases CO₂ and other gases.
- Soil Degradation: Heat alters soil composition, affecting vegetation.
- Safety Risks: Gas leaks can cause secondary explosions if unmanaged.
Cultural Significance - Locals view the flame as a symbol of resilience.
- It attracts tourists, boosting regional awareness.
- The site has become a heritage landmark, much like eternal flames in other countries.
