The nation’s biggest cities are sinking, revealing a pressing urban challenge. A recent study published on May 8, 2025, highlights that at least 20% of urban areas across 28 major U.S. cities are experiencing land subsidence, primarily due to excessive groundwater extraction.
- Major cities experiencing significant land subsidence
- Groundwater extraction is the primary cause
- Houston is the fastest-sinking U.S. city
- Subsidence impacts infrastructure and safety
- Some cities show negligible uplift instead
- Population growth may worsen subsidence issues
This phenomenon isn’t limited to coastal cities; many interior areas are also affected. The study, led by Leonard Ohenhen from the Lamont-Doherty Earth Observatory, emphasizes the need for urban planning and infrastructure adaptation to combat this invisible threat.
Why should we be concerned about subsidence? The implications for infrastructure and urban safety are significant. As cities continue to grow, the stresses from sinking land could exceed safety limits for buildings and roads. Key points include:
- Over 40% of Houston is sinking at alarming rates.
- Subsidence can lead to severe structural damage.
- Continued population growth exacerbates the problem.
- Climate change may worsen subsidence through droughts.
As we face these challenges, proactive measures and innovative solutions are essential to safeguard our cities and communities for the future.
