US Cities Are Literally Sinking!
New research reveals a shocking truth: major US cities are sinking, threatening buildings and infrastructure. This subsidence, primarily caused by groundwater depletion, is impacting millions.

- Widespread Subsidence: A new study using satellite data shows widespread land subsidence in major US cities, including New York City, Seattle, San Diego, Denver, Dallas, Chicago and more. This means the ground is slowly sinking.
- Building Damage: Approximately 29,000 buildings are at risk of damage due to uneven sinking and worsening flooding. Uneven sinking is particularly problematic, putting strain on buildings and infrastructure.
- Houston: The Fastest Sinking City: Houston is identified as the city experiencing the fastest rate of sinking, with consequences already seen in post-hurricane flooding.
- Causes: The primary cause is groundwater extraction, but factors such as oil and gas extraction, the weight of buildings, and even the lingering effects of past ice ages play a role.
The Dangers of Uneven Sinking:
Uneven sinking creates significant risks, including:
- Increased flooding
- Tilted buildings
- Cracked foundations
- Damaged bridges
What Can Be Done?
The study highlights the need for immediate action, focusing on better groundwater management and improved building codes in high-risk areas.
The future of these cities depends on effective solutions to this growing problem.
