Fig. 2

a ALOS-2 image showing the line-of-sight (LOS) ground motion during the 2016 Kaikōura earthquake, New Zealand. Each coloured fringe corresponds to 11.4 cm of deformation. Heavy black lines show the faults that slipped. From4 b Best-fitting slip model for the 2016 Kaikōura earthquake, including slip on the subduction interface and at least 12 major structural faults. From4 c East-west velocity of the Anatolian microplate derived from the first 5 years of Sentinel data combined with ground-based GNSS measurements from ref. 9. Black lines are active faults from ref. 20. d Sentinel-1 image showing a magmatic intrusion on the flanks of Sierra Negra volcano, Galapagos and subsidence at the summit. Each coloured fringe corresponds to 2.8 cm of motion in the satellite line-of-sight. e The image in d classified using the convolutional neural network of ref. 19 to automatically identify areas of deformation. Contours show probabilities of 0.5 and 0.8, respectively.
