Ascending track 184, ScanSAR mode, Sep 5, 2022 - Feb 20, 2023. Color fringes indicate changes in the radar range (one color cycle corresponding to 11.8 cm of line-of-sight displacements). Stars denote the earthquake epicenters, and dark red and blue lines denote surface traces of the respective earthquake ruptures determined from Sentinel-1 SAR data. Black wavy lines denote the geologically mapped fault traces.
