Here's some recent global infrastructure news from Thuringia, Germany: a 30-meter wide, 25-meter deep sinkhole recently opened up in an unsuspecting neighborhood to swallow up some property. In this case, the only losses were a car, some road, and a driveway and garage door.
The sinkhole, which is one of the largest ones to form in Thuringia, is suspected to be the result of "a salt column, calcium sulphate or limestone [dissolving]". According to reports, the region averages twenty smaller sinkholes a year.
