Denver, Dallas among the Major U.S. Cities Sinking into the Ground

All 28 of the most populous U.S. cities are sinking, with at least 20% of each city's area affected, increasing flooding risks and potential infrastructure damage. Groundwater extraction is the primary cause in 80% of cases. Houston, Fort Worth, and Dallas are sinking fastest, averaging over 4mm annually. Satellite radar detected varied sinking rates across cities, revealing risks to buildings and the formation of flood-trapping "subsidence bowls." Drought-prone regions face higher risks as aquifers deplete.
