NASA Satellite Reveals Mexico City's Rapid Sinking, Threatening Infrastructure
Mexico City, one of the largest cities in North America, is experiencing significant subsidence, sinking nearly 10 inches annually. This alarming rate of descent has been captured by NASA's NISAR satellite, which monitored the city from October 2025 to January 2026. The data reveals that areas such as the central airport and the Angel of Independence monument are subsiding at a rate of 0.78 inches per month. The city's foundation, originally built on an ancient lake bed, is being compromised due to extensive groundwater pumping and urban development, leading to near-depletion of the aquifer. This has caused some regions to sink over 39 feet in less than a century, with certain areas experiencing elevation changes of up to 127 feet. The subsidence is visibly affecting critical infrastructure, including the subway, drainage, and water systems.
