Mexico City Is Sinking Fast

Mexico City, home to nearly 22 million people, is sinking at an alarming rate that can be observed from space. NASA's powerful NISAR satellite system has revealed that parts of the city are subsiding by more than 0.5 inches per month, making it one of the fastest-sinking capitals on the planet.
The sprawling metropolis is built on top of an ancient aquifer that supplies approximately 60% of the city's drinking water. Years of over-extraction from this underground water source have caused the land above to sink. This over-pumping has also contributed to a severe water crisis, with the city facing the possibility of taps running completely dry.
The problem has been made worse by continuous urban development, which adds extra weight to the clay-rich soil beneath the city. Between October 2025 and January 2026, NISAR data showed some areas sinking at rates of 0.8 inches per month—more than 9.5 inches annually. The consequences are visible everywhere: fractured roads, tilted buildings, and damage to infrastructure including the Benito Juarez International Airport. The famous Angel of Independence monument has required 14 additional steps at its base as the ground beneath it continues to sink.
