The Arizona Geological Survey has discovered a new crack in Pinal County.

The Geological Survey announced Monday that they found the fissure, which they explored with drone video. The fissure is about 25 miles south of Arizona City.

The fissure is believed to have formed between March 2013 and December 2014. It is more than half a mile longer than other fissures in the area.

"Earth fissures are associated with basin subsidence that accompanies extensive ground water mining," according to The Arizona Geological Society's web page on earth fissures.

Not only are fissures potentially hazardous, particularly because they erode quickly during torrential rains, but they also "provide a ready conduit to deliver runoff and contaminated waters to basin aquifers."

Fissures are fairly common in central Arizona. There are clusters of fissures around Eloy and in Cochise, La Paz, Maricopa, Pima and Pinal Counties.

Arizona City is about an hour southeast of Phoenix along Interstate 10. Tator Hills, which is where the fissure is located, is another 25 minutes past Arizona City.
