primordial fear, the ground opening up beneath your feet. That's what is happening tonight to an entire neighborhood in central Florida, a giant sinkhole forcing families out of their homes. ABC's Matt Gutman is on the story. Reporter: As these homeowners slept, a massive sink hole swallowing up the Earth beneath them. Growing more than 100 feet across and 30 feet deep. Out of nowhere the Earth just went straight up in the air, exploded up in the air straight up. Reporter: Crumpling asphalt like cardboard, all in just 30 minutes. Four homes evacuated, police ordering people to get out. It's just 50 miles from a town where last year a man who was sleeping in his bed was killed in a sinkhole. Months before that, this condo sinking right into the Earth caught on tape. About 20% of the country is vulnerable to sink holes but Florida has more than any other state, about 60 a year. Because the ground is full of limestone and sinkholes generally form when limestone is eaten away by water. Are there any ways to detect whether or not you have a sinkhole in or around your house? Very expensive and difficult to do. It might only be good for as long as the test is done. Reporter: As for this sinkhole which doubled in size in just a few hours, it's now stable but will soon be filled in with cement. Most of the people who live here have been given the all clear to return home. Matt Gutman, ABC news, Miami.
