28 Most Populous US Cities Are Sinking, New Survey Finds
- A 2025 satellite radar study found that all 28 most populous US cities with over 600,000 residents are experiencing varying degrees of land subsidence.
- Researchers attribute subsidence primarily to massive groundwater extraction and human activities like oil and gas pumping, with climate-induced droughts likely worsening the trend.
- Notable cities include Houston, the fastest-sinking city where over 40% of land sinks faster than 5 millimeters annually, and multiple Texas cities showing rapid subsidence rates around 4 to 10 millimeters per year.
- Leonard Ohenhen, the lead author of the study, cautioned that ongoing land sinking could create forces on buildings and infrastructure that exceed their designed safety thresholds, with nearly 29,000 structures situated in areas experiencing significant ground movement.
- The study urges policymakers to adopt groundwater management and resilient infrastructure planning to mitigate subsidence-related damages and address growing urban risks effectively.

All of the biggest U.S. cities are sinking
A new study of the 28 most populous U.S. cities finds that all are sinking to one degree or another. The cities include not just those on the coasts, where relative sea level is a concern, but many in the interior. Furthermore, using newly granular data, the study finds that some cities are sinking at different rates in different spots, or sinking in some places and rising in others, potentially introducing stresses that could affect buildings a…
