LOUISVILLE, Ky. (AP) — Solid ground isn't always a certainty. Sinkholes can lurk anywhere, beneath suburban homes, city streets or even football stadiums and museums.
It's basic geology: sinkholes strike when soil collapses into large holes, caused by flowing water in underground limestone. The toll can be dramatic when the voids open, swallowing homes, trees or anything else on the collapsing ground — even prized Corvettes.
The Southeastern U.S. is prime territory for the geological phenomena — a potentially costly game of subterranean roulette.
In Tennessee, a sinkhole opened during renovations on the football stadium at Austin Peay State University. In Kentucky, a sinkhole gobbled eight classic cars on display at the National Corvette Museum in Bowling Green.
