Longer than that. wiki ;

The Centralia mine fire is a coal seam fire that has been burning underneath the borough of Centralia, Pennsylvania, United States, since at least May 27, 1962. The fire is suspected to be from deliberate burning of trash in a former strip mine, igniting a coal seam.

I lived near it in 1968 and it was going pretty good then.

I did too....visited there when you could see the smoke coming out of the ground among dead trees etc. as you drove through there. Pretty dark looking for sure !
