Repairs are to begin Wednesday on a 65-foot-deep (20 meters) sinkhole that opened in the eastern German town of Schmalkalden on Monday, local authorities said.
The sinkhole, which measured more than 130 feet (40 meters) across, swallowed a car and forced the evacuation of 25 people in nine houses, the regional newspaper Thueringer-Allgemeine reported.
Officials told the paper more than 1,000 truckloads of gravel would be needed to fill the hole.
Residents reported hearing a loud roar as the earth gave way early Monday morning, according to the newspaper report. The cause of the sinkhole had not been determined.
Jürgen Reinholz, environment and agriculture minister for the state of Thuringia, said natural causes were suspected, according to Spiegel Online International.
