method of pointing out changes in vector field Explanation: Satellite Radar SAR Interferometry or InSAR (Interferometric Synthetic ApertureRadar) is a synthetic aperture radar data processing method (PCA). The method is very effective in solving problems of monitoring the dynamics of the Earth’s surface over a period between repeated satellite radar surveys. |

displacement vector field reconstruction procedure Explanation: We reconstructed the three-dimensional (3D) surface displacement field of the 24 August 2014 M6.0 South Napa earthquake using SAR data from the Italian Space Agency’s COSMO-SkyMed and the European Space Agency’s Sentinel-1A satellites. Along-track and cross-track displacements produced with conventional SAR interferometry (InSAR) and multiple-aperture SAR interferometry (MAI) techniques were integrated to retrieve the east, north, and up components of surface deformation. 3D surface displacement maps derived by combining multiple InSAR and MAI displacements measured from CSK and S1A data: (a) east, (b) north, and (c) up components of displacement. (d) 3D displacement vector field with arrows showing horizontal movement and colours showing vertical movement from the earthquake. Black small squares and red star represent the locations of GPS stations and the epicentre, respectively. Profile A-A’ is shown in more detail in Fig. 5. The maps were generated by using the GMT software 5.3.2 version The displacement vectors shown in Fig. 4d were computed by combining the east and north components of the 3D measurements. https://www.nature.com/articles/s41598-017-06018-0 ccccccccccccccccccccccc |
