Centralia, Pennsylvania has been burning since 1962. Or rather, the ground beneath the town is burning: an underground coal seam fire that caused the town to be mostly abandoned has been burning for over 50 years, and will continue for at least another 250. The fire likely began when a trash fire ignited the coal seam in the network of old mines beneath the town. Gradually, a slow apocalypse took place: snow couldn’t always stick to the heated ground, vegetables could grow year-round, the main highway sunk eight feet, and residents began to pass out from carbon monoxide gas issuing from their basements. By 1991, the town was almost entirely government-owned under eminent domain, and in 2002 the ZIP code was revoked. The few residents that remain do so at their own risk.
