The town of Centralia, Pennsylvania has been on fire since 1962. No one knows how the fire started, but it began in a mine beneath the town. Most of the town’s citizens have abandoned the place. The estimated population is that of 10 people.
“Centralia had a segment entitled “City on Fire” on the television series America Declassified which aired December 1, 2013. A geoscientist took a small drone equipped with an infrared camera and surveyed the top surface of the town from about 200 feet in the air. The purpose of the test was to see if the coal fire was still burning below the surface, or has diminished. His conclusion was that the fire was indeed still burning at a significant rate.”
