This massive sinkhole measuring 131 feet wide recently opened up about two miles away from a Russian mine. First, flooding stopped operations at the mine about a 1,000 miles east of Moscow. Then, the Russian fertilizer company evacuated the mine to protect their workers.
This could help investigators know where the flooding is coming from and how to stop it. The Moscow Times says the area surrounding the sinkhole has been abandoned since 2005 because officials thought the land might in fact be sinking.
