A one-kilometer long earth crack opened up on 15th of August 2014, in Sonora, Mexico. The crack severed Highway 26 between the city of Hermosillo and the coast. At some points it is 5 meters wide and 8 meters deep.
According to El Imparcial newspaper, it is still unknown what caused the crack but Municipal Civil Protection believes that it was triggered by an underground water stream. Some speculate that an earthquake at the San Andreas Fault last Sunday may have been the cause.
Geological investigations are underway. Another crack was reported to have opened near Highway 4 in the same area.
