Mexico City sinking up to 2 cm monthly as NASA satellite data alarms scientists

Millions of residents in Mexico City face potential infrastructure collapse, displacement risks, and threats to water systems and building stability from accelerating subsidence.

Beneath one of the world's great cities, the earth is quietly giving way. Mexico City — built by the Aztecs upon a lake and sustained for centuries by underground water — is sinking at a rate of roughly twenty-five centimeters per year, a pace now confirmed with unsettling precision by NASA's NISAR satellite. The city's ancient bargain with its aquifer is coming due: decades of extraction have compressed the soil beneath nineteen million people, and the infrastructure holding their lives together was never built for a ground that will not hold still.
