Centralia is a borough and near-ghost town in Columbia County, Pennsylvania, United States. Its population has dwindled from more than 1,000 residents in 1980 to 63 by 1990, to only five in 2017—a result of the coal mine fire which has been burning beneath the borough since 1962. https://www.history.com/news/mine-fire-burning-more-50-years-ghost-town
