A Kentucky zoo has closed while engineers study a newly discovered sinkhole nearly as large as a football field.
Louisville Zoo spokeswoman Kyle Shepherd told news outlets the sinkhole was found Wednesday in an undeveloped area away from any zoo animals. She said no people or animals were reported injured and no buildings damaged.
Louisville Metro Emergency Services Director Jody Meiman says officials estimate the sinkhole is about 50 yards by 85 yards (45 meters by 75 meters) and about 50 feet (15 meters) deep in spots.
The nearby Louisville Mega Cavern also said Wednesday it is temporarily closed because of a 3.4 earthquake reported Tuesday in neighboring Tennessee.
Officials said they haven’t determined whether the earthquake caused the sinkhole. Meiman says causes could include rain or “natural occurrences” underground.
