Plots of InSAR data measuring the 2017 nuclear test in North Korea

Scientific plots of surface deformation
(Top) InSAR data in ascending and descending orbits depicting surface deformation associated with the 2017 nuclear test. (Bottom) Comparison of the source location of the 2017 nuclear test estimated from this study (red star) with other estimations. Topography along profile CD showing the cavity, deformation zone and probable location of tunnel. Note that the sizes of the cavity and deformation zones are exaggerated by 5 times for better visualisation.
