A massive sinkhole was discovered near Route 61 in Centralia, Columbia County in central Pennsylvania last week.
The hole is estimated to be 100 feet deep and 15 wide. Department of Environmental Protection workers did not know the exact date when the sinkhole appeared. They also added that it does not seem to be getting bigger. Large rocks and boulders are now being used to fill the hole and repair work will continue this week.
According to the DEP’s Bureau of Abandoned Mine Reclamation, the hole is not related to the underground fire that’s been burning the area since 1962. Instead, it might be caused by mine subsidence from a different underground coal seam which occurred before the blaze.
During the late 1980s, a federal relocation program worth $42 million moved the residents out of Centralia, making it an almost deserted town, with only a few people still living there.
