Surface Subsidence Map from Sentinel-1 InSAR, 2016-2018, Teshekpuk, Alaska (US)

Surface subsidence was derived from Sentinel-1 synthetic aperture radar time-series with a spatial resolution of 5 m. Maps show the averaged displacement rates during the snow free seasons of 2016 to 2018. Subsidence is in the satellite line-of-sight direction (incidence angle ranges between 29.1° and 46.0°) and is restricted to areas where interferometric coherence is sufficiently high.
