Synthetic Aperture Radar

Areas shown in blue on this map are subsiding, with darker blue areas sinking faster than lighter blue ones. The areas shown in dark red are rising the fastest. The map was created by comparing thousands of scenes of synthetic aperture radar (SAR) data collected between 2007 and 2011 and 2014 and 2018.
