On November 18, 2014, a mine operated by the Uralkali corporation in Solikamsk, Russia (about 1,000 miles northeast of Moscow), experienced flooding, and the compound was evacuated. Later it was discovered that the groundwater had caused a sink hole to form in the area, which was initially measured to be about 30 meters (100 feet) wide. Over the past nine months, the hole has gotten a tad bigger, growing as wide as 125 meters (410 feet). On the popular Russian social network Odnoklassniki, several aerial photos of the disaster recently appeared in a local community group.
