NISAR (NASA-ISRO Synthetic Aperture Radar) satellite can track real-time changes across Earth's surface from orbit.
NISAR satellite captured real-time ground subsidence across Mexico City between October 2025 and January 2026.
KEY POINTS
- NISAR's L-band radar can detect land subsidence even in densely vegetated or cloud-covered regions.
- Initial NISAR data revealed some Mexico City areas are sinking over 2 centimeters per month.
- Yellow and red areas in NISAR imagery are noise, expected to decrease with continued data collection.
- NISAR's global coverage is expected to reveal similar land subsidence issues worldwide.
