Mexico City Is Sinking So Fast NASA Can Track It From Space

The findings highlight how infrastructure, housing, and historic landmarks are increasingly at risk, with scientists warning of worsening water shortages and structural damage.  

Why Mexico City Is Sinking  

Mexico City’s foundation rests on soft lacustrine soil from an ancient lake system. Excessive groundwater pumping over decades has caused the aquifer beneath the city to shrink, leading to subsidence. Streets tilt, drainage systems crack, and monuments like the Metropolitan Cathedral visibly sink.  

Impact On Infrastructure  

Subsidence has damaged critical infrastructure including the metro system, drainage networks, and housing. Some areas have sunk more than 39 feet over the past century, creating uneven ground that fractures buildings and disrupts transport systems.  

NASA’s Satellite Evidence  

NASA’s NISAR satellite, developed with ISRO, provides high-resolution radar imagery that tracks subsidence in real time. The data shows widespread sinking across the city, offering policymakers crucial insights for water management and urban planning.  

Future Concerns  

Experts warn that without urgent reforms in groundwater use, Mexico City’s water crisis will intensify. Millions of residents could face severe shortages, while infrastructure damage may escalate, threatening the city’s long-term sustainability.  

Subsidence Highlights  

• Mexico City sinking nearly 10 inches annually  
• Groundwater depletion is the primary cause  
• Historic landmarks and housing visibly affected  
• NASA-ISRO NISAR satellite confirms subsidence patterns  
• Threatens water supply and transport systems
