Centralia, Pennsylvania, is a small town with a population of 35 people. In 1962 a coal mine caught on fire and it\’s been burning underground ever since. Attempts to put out the fire all failed, and in the worst case the fire will burn for another 100 years. I thought this was a really interesting story. The fire\’s been going on for 40 years, and there\’s nothing that can be done about it. Most of the 1100 former residents have relocated, and the town itself is pretty much destroyed.
