Recent research has revealed that 25 of the most populous U.S. cities are experiencing land subsidence, with rising concerns for structural integrity. These cities compress across two-thirds of their area, impacting around 34 million people, or 10% of the U.S. population. Although it may not appear problematic now, the gradual sinking of land poses significant risks for urban infrastructure and future development. This study, published in Nature Cities, emphasizes the ongoing need for awareness regarding land stability in urban environments.
The researchers discovered that all 28 of the most populous U.S. cities are experiencing some degree of vertical land movement, with 25 cities subsiding significantly.
The study shows that approximately 34 million people, around 10% of the U.S. population, reside in areas facing notable land subsidence.
Land subsidence may seem minor now, but the long-term structural integrity of buildings in sinking areas is at risk, raising concerns for urban development.
This research highlights a pressing issue that could affect future urban planning and infrastructure stability across major U.S. cities.
