Thank you, Ron. Cops and geologists are on the scene of a metastasizing sink hole in a parking lot. And the question is, how to stop it. ABC's Reena ninan is right there this morning. Reena, good morning. Reporter: Good morning to you. The big concern overnight is the heavy rain. Police and geologists worry it could open up even further. While there's plenty of team coming by to take selfies with the sinkhole, officials warn at this hour, that ground behind me is still unstable. Check out this 85-foot-long, 18-foot-deep crater that's getting bigger by the minute in a parking lot just across the street from Florida's legoland theme park. Engineers and geologists are working all night to figure out their next move, while onlookers seem more curious than worried. This growing cavity is just 40 miles from the 2013 sinkhole that opened up beneath Jeff bush's bed, swallowing him up as he swept. His body was never recovered. My brother-in-law's in there. And he's underneath the house. Reporter: A new months later, experts believe a sinkhole was behind this collapse in a central Florida vacation resort near Disney world. We heard a big boom. And then, the bathtub lifted up and went down. Reporter: Collapses are part of the risk of living in the sunshine state. According to Florida's geological survey, there's been 296 depressions since 2010. More than 50,000 square feet of land devoured. Claire who works in publix grocery store, says the ground collapsed in less than an hour and a half. I parked at 5:45. Went in the store. And about 7:30, my boss said, grab your keys. There's a sinkhole behind your car. Reporter: There's those who know better. This is scarier than an earthquake. Reporter: Thankfully, no one was hurt. The next step is to drill the ground for soil samples to determine if it is stabilizing. There's nearly 300 reported cases in Florida, as well. Reena, you're on vacation. You're a diligent worker. Getting up for us this morning, despite being on vacation to bring us this story. Thank you. Enjoy the rest of your vacation. Reporter: You bet. Legoland was fantastic. I'm glad you enjoyed it. We're going to stay in
