NISAR Space Radar Reveals Mexico City's Ongoing Ground Subsidence
New data from NASA-ISRO's NISAR radar show parts of the Mexico City region sinking by a few centimeters per month (Oct 2025–Jan 2026) due to long-running groundwater pumping and compaction of an ancient lakebed; the subsidence has damaged infrastructure and landmarks, and NISAR’s all-weather, dual-band radar enables persistent monitoring of land motion in densely populated or vegetated regions.
