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.
JĆ¼rgen Reinholz, environment and agriculture minister for the state of Thuringia, said natural causes were suspected, according to Spiegel Online International.
