Earth fissures of south-central Arizona are pervasive ground cracks measuring up to a mile or more in length, and up to 15 feet wide and 40 feet deep.  The State Legislature, recognizing that fissures presented a hazard to people, property and infrastructure, charged the Arizona Geological Survey in 2007 with: 1) mapping all existing earth fissures in Arizona; and, 2) making fissure maps publically available.
