InSAR

InSAR, or Interferometric Synthetic Aperture Radar, is a remote sensing technique that uses radar signals from satellites to measure ground movement with high precision. By capturing images of the Earth's surface at different times and comparing their phase differences, InSAR can detect tiny shifts—such as volcanic uplift, land subsidence, or earthquake-induced shifts—often just millimeters. This method is valuable for monitoring natural hazards, land deformation, and environmental changes over large areas safely and repeatedly, providing crucial data for scientists and engineers to understand and respond to geological processes.
