The subsiding basins are all in the Basin and Range province of Arizona, and are those with extensive agriculture or urban development.
Using InSAR and GPS data, "ADWR has identified more than 25 individual land subsidence features in Arizona, collectively covering more than 1,200 square miles of the state."
ADWR has posted 199 land subsidence maps online for downloading.
AZGS contributes funding to the state program.
