MORE THAN 20 PEOPLE were forced to leave their homes in Schmalkalden, central Germany, yesterday as a huge sinkhole opened in a residential area.
No one was injured when the enormous hole developed.
Sinkholes can be caused by the underground erosion of salt beds or soluble sedimentary rocks, according to the Christian Science Monitor.
Water flowing through those rocks can erode them, causing caverns to develop beneath the surface which can then suddenly collapse.
The hole has a radius of 30 metres, and is believed to be about 20 metres deep. An empty car was pulled underground as the hole expanded, according to Der Spiegel.
