Featured Earthquakes Observation Method: Sentinel-1 C-SAR

The Synthetic Aperture Radar (SAR) aboard the ESA (European Space Agency's) Sentinel-1A/B satellites provides continuous all-weather, day-and-night land imagery. SAR images can be combined to produce interferograms, which are images showing changes in land height or position associated with earthquakes.
