NASA Data Shows Mexico City Sinking Faster Than Expected

New satellite measurements are putting fresh numbers on a problem Mexico City has lived with for generations. NASA’s NISAR mission found areas of the capital sinking more than two centimeters per month, a rate that can quietly reshape roads, water lines, homes, and drainage systems. The new map does not mean the whole city is dropping at the same speed. It shows something more difficult for planners: uneven movement beneath one of the world’s largest urban areas.
