A large expanding crack appeared in Northern Cape, South Africa, between the cities of Daniëlskuil and Kuruman, following the heavy rains that hit the region at the beginning of January.
The crack is located about 55 km south of Kuruman and was discovered on January 6, 2017. On January 13, it was about 300 m (980 feet) long and 30 m (98 feet) deep; and it is still increasing in size. As it is dangerously approaching R31 road, which runs between the two cities, the road is now officially closed by the Department of Roads & Public Works for precautionary reasons.
The crack is believed to be a natural sinkhole formed due to the karst topography of the area. The region consists of soluble rocks such as limestone, dolomite, and gypsum and is characterized by underground drainage systems with sinkholes and caves. It seems to be used to such formations, since the Boesmansgat sinkhole - one of the world's deepest submerged freshwater caves - is also located nearby.
