NASA radar shows Mexico City's rapid subsidence threatening water and infrastructure
TL;DR Summary
Mexico City is sinking at up to about 0.8 inches per month (roughly 9.5 inches per year) due to over-pumping of its ancient aquifer. NASA’s NISAR radar maps reveal the pace of subsidence, accelerated by dense development on clay-rich soils, and the ground drop is fracturing roads and infrastructure while threatening the city’s water supply for about 22 million residents, raising concerns of a potential day zero if groundwater loss continues.
