Almost a week after a giant sinkhole opened near a copper mine in the Atacama desert, geological experts say they're no closer to figuring out what caused the phenomenon than they were then.
- The huge opening, which measures 104 feet in diameter and is twice as deep, unexpectedly appeared over the weekend nearly 500 miles north of Santiago, according to the National Geology and Mining Service. Despite it's proximity to a mine operated by Canada's Lundin Mining, experts say there's no indication that the operation had anything to do with the opening. No workers were injured as a result of the sinkhole, officials say.
- While the investigation into the sinkhole's origin continues, "development work in an area of the Alcaparrosa underground mine has been temporarily suspended," a rep for Lundin Mining says.
- Why do people seem to be so fascinated by sinkholes?
