Miners in Pennsylvania have long excavated anthracite coal for its appeal as long-burning coal. Towns filled with workers and their families popped up near mines, and Centralia was no exception.
In 1962, a common municipal trash burn outside town led to something out of the ordinary: fire struck a coal vein, igniting an underground blaze that has been burning ever since. By the 1970s, the fire had spread under the town, with plumes of toxic gas spewing from cracks in the earth.
While some residents reported illness from carbon monoxide poisoning, the town remained relatively unchanged until 1981, when a 12-year-old boy fell into a sinkhole. Nearly killed by the heat and toxic fumes, he became the poster child for Centralia's continuing problem. In 1983, Congress authorized $42 million for the relocation of the town's residents [source: Rubinkam].
Though the government condemned Centralia's buildings and razed about 500, some die-hard residents remain. Until recently, one of those die-hards was 39-year-old John Lokitis Jr., the subject of a 2007 documentary on Centralia. In 2010, Lokitis' childhood home was leveled by the government. Fewer than a dozen residents remain.
Not all boom towns meet their end from natural disaster. Our final boom town collapsed under the weight of a worldwide recession.
