US–Indian space mission maps extreme subsidence in Mexico City‎

One of the most powerful radar systems ever launched into space has mapped the ground moving beneath one of the fastest subsiding capitals in the world: Mexico City. The findings show how quickly and reliably the NISAR (NASA-ISRO Synthetic Aperture Radar) satellite can track real-time changes across Earth's surface from orbit, unhindered by clouds or vegetation that impede optical sensors and higher-frequency radars.
