Mexico City Is Sinking. A Powerful NASA Satellite Just Revealed How Fast

NASA’s new NISAR satellite found Mexico City is sinking unevenly, with some areas dropping more than 2 centimeters per month.

The preliminary measurements from October 2025 to January link the subsidence to groundwater extraction and the city’s heavy load on ancient lakebed soil.

The sinking is accelerating infrastructure risk for buildings, the metro, and Benito Juarez International Airport, affecting millions of residents.
