A modern-day ghost town, Centralia, Pennsylvania, is the site of an underground coal mine fire that has been burning for nearly 50 years. In 1962, the planned burning of a landfill ignited an exposed vein of coal, leading to an underground conflagration that now underlies approximately 400 acres (1.6 sq km). The state has condemned all of Centralia’s buildings, yet a handful of residents remain there, despite sinkholes, escaping gases, and health warnings. How long is the fire expected to burn? Discuss
