The Centralia mine fire is a coal-seam fire that has been burning underneath the borough of Centralia, Pennsylvania, United States, since at least May 27, 1962. Its original cause is still a matter of debate. At its current rate, it could continue to burn for over 250 years.
How did the coal vein in Centralia catch on fire?
No one quite knows how the Centralia fire started. The leading theory today is that burning trash near an old mine entrance accidentally ignited the coal beneath. Once it ignited, the fire began to spread. Once started, the fire will keep burning as long as there’s enough heat, fuel, and oxygen to sustain it.
What is clinker rock?
According to Grapes (2006) Clinker is a hard, fused and/or partially melted sedimentary rock, with well preserved shaley texture, forming in burnt coal seams or bituminous sediments.

A coal seam is a dark brown or black banded deposit of coal that is visible within layers of rock. These seams are located underground and can be mined using either deep mining or strip mining techniques depending on their proximity to the surface.
Why is Centralia a ghost town?
The formerly busy burg has turned into a ghost town. The cause was something that’s still happening beneath Centralia’s empty streets: a mine fire that’s been burning for over 50 years, resulting in the devastation of a community and the eviction and impoverishment of many of its residents.
Is Silent Hill still burning?
Roughly 500 buildings were demolished, leaving the town looking like a scene out of the 2006 horror film Silent Hill (which was, in fact, partially inspired by Centralia).

Why can’t the Centralia fire be put out?
However, experts believe the fires under Centralia could burn another 250 years before they exhaust the coal supply that fuels them. Why don’t firemen simply put them out? They can’t! The fires are too deep and burn too hot to be fought effectively.
