New land subsidence maps from AZ Dept. of Water Resources

Land subsidence maps have been updated on the Arizona Dept. of Water Resources website using InSAR (satellite interferometry) data through 2014, according to Brian Conway, head of the Geophysics/Surveying Section. You can access the maps for each land subsidence feature at this link: http://www.azwater.gov/AzDWR/Hydrology/Geophysics/LandSubsidenceInArizona.htm I copied the subsidence for the West Valley (Phoenix basin) from May 2010 to April 2014 as one example.
