Subsidence could cost some U.S. homeowners 8.1% of their home’s value

The land beneath many U.S. cities is sinking. This natural and man-made phenomenon, known as subsidence, can directly affect home prices and put critical infrastructure like railroads and airports at risk. Fortunately, some of the subsidence can be reversed. “It’s not cheap, it’s not easy, but we have the tools in our toolbox that can do it and see the results months or years later,” said Manouchehr Shirzaei, professor of geophysics and remote sensing at Virginia Tech.
