An underground mine fire gone seriously wrong led to this modern ghost town northwest of Philadelphia. In 1962, a fire accidentally spread to the town's old, underground mines, creating sinkholes that spewed smoke and toxic fumes across the community. In 1983, most of the town was evacuated, and in 1992, its real estate was claimed under eminent domain and condemned by the state (delivering the final blow, the ZIP code was officially recalled in 2002). Even though Centralia's fire is still burning today—and expected to burn for another 250 years—four residents still live in the doomed town as of 2020 (sounds like they’re playing with fire, if you ask us). Only five homes remain standing in this town.
