Six months of post-seismic surface displacements along (a) ascending and (b) descending tracks. InSAR signals suspected to have been caused by topographic variations and/or regions of low coherence are masked out for better clarity. (c) and (d) Time-series LOS displacements, seasonal and noise components, and post-seismic deformation extracted from SSA at point P1 (ascending) and P2 (descending), respectively. Light blue dots indicate InSAR measurement for each observation date and solid red and blue lines are the logarithmic and exponential model displacements. Model parameters are shown in the inset table.
