Centralia is a small, nearly abandoned town in Pennsylvania, known for its underground coal fire that has been burning since 1962. The fire started due to a landfill fire that ignited a coal seam, leading to a series of dangerous conditions, including ground subsidence and toxic gas emissions. As a result, most residents were forced to evacuate, and the town has become a ghost town. Today, Centralia is often visited by urban explorers and those interested in its unique history. The once-thriving community has been reduced to a few remaining buildings and a network of cracked roads, with the Graffiti Highway being a popular site for photographs. The fire is expected to continue burning for decades, making Centralia a notable example of environmental disaster.
