DescriptionThe Arizona Geological Survey (AZGS) is tasked by statutes approved in House Bill 2639 of the 2006 legislative session to undertake comprehensive mapping of earth fissures and deliver earth fissure map data to the State Land Department (SLD) starting in 2007 and every five years subsequently (Appendix A). The legislation and funding for the AZGS became effective on September 21, 2006. Earth fissures have developed around the margins of most Arizona basins where the land has subsided more than a few feet. The potential for risk and damage to property from earth fissures has increased due to urban development into fissure-prone areas, and due to continued basin subsidence which results in earth fissures forming at depths of hundreds of feet and propagating to the surface.
