A recent study has revealed that many of the largest cities in the United States are gradually sinking, with the primary cause in most cases linked to the overextraction of groundwater. According to researchers, the ground beneath all 28 major metropolitan areas surveyed is subsiding at rates ranging from two to ten millimeters per year.
The findings come from a research team at Columbia University in New York, as reported by the science outlet Scinexx. Using high-resolution radar satellite data collected between 2015 and 2021, scientists assessed ground movement across U.S. cities with populations exceeding 600,000 residents. They then compared this data with groundwater usage records to identify correlations.
