Parts of metro Phoenix are sinking by about three-quarters of an inch a year, according to new research by Arizona State University.
The culprit: large amounts of groundwater pumped years ago.
Scientists at ASU’s School of Earth and Space Exploration say ground-elevation levels in Apache Junction are seeing the fastest drop. Sun City West, Peoria and the north Valley are also descending.
People shouldn’t panic, said ASU researcher Megan Miller, co-author of the study published recently in the Journal of Geophysical Research.
