March 10, 2013 | Tucson Citizen
The Tucson Citizen has an article about sinkholes in Arizona. Like in Florida, karst features in Arizona can develop over limestone, but gypsum and salt can also support karst topography.
Publications from the Arizona Geological Survey include:
Home Buyer's Guide to Geologic Hazards in Arizona
Land Subsidence and Earth Fissures in Arizona
Natural Hazard Viewer for Arizona
September 24, 2013 | Arizona Geological Survey
The interactive Natural Hazard Viewer focuses on four hazards common to Arizona — geologic faults and earthquakes, earth fissures, floods and wildfire. Each hazard is described in detail and displayed as a layer on a map. Moreover, the natural hazard information is dynamic; site updates will occur as new or revised hazard data becomes available.
Editor's Comment: Every state geological survey should have one of these!
