Interferometric Synthetic Aperture Radar (InSAR)

InSAR (Interferometric Synthetic Aperture Radar) is a radar technique used in geodesy and remote sensing. A technique for mapping the earth’s surface from satellites. 

How accurate is InSAR?

InSAR can capture small earth movements ground deformation over a large area at high-resolution images of meters, centimeters, or even mm. But this is very speculative. 

InSAR can be used for a wide range of surface deformation studies,

Subsidence and uplift induced by anthropogenic activities such as groundwater or hydrocarbon extraction, or reinjection into reservoirs during carbon capture and storage

Coseismic deformation caused during an earthquake

Postseismic and interseismic deformation on crustal faults between earthquakes

Inflation/deflation of subsurface magma chambers preceding volcanic eruptions

Monitoring surface movements in urban environments.
