This episode explores the story of Centralia, Pennsylvania, a ghost town that has been burning for decades. The town's decline began with the decline of the coal mining industry, and a fire that started in a landfill in 1962 has been burning underground ever since. The fire has caused sinkholes and released toxic gases, leading to the evacuation of the town. The government eventually used eminent domain to condemn all the buildings in the area. Centralia has become a subject of fascination and has been featured in books, documentaries, and films.
