#### *5.1. Post-Seismic Displacement Field*

Figure 2 shows the line-of-sight (LOS) displacements from ascending and descending orbits after the earthquake (17 and 18 November 2017, respectively) to February 2020, where the positive value means movement towards the sensors and negative values mean movement away from the sensor. The ascending data shows a lobe of up to 8 cm of LOS decrease (yellow/red color) and the descending data shows lobes of both LOS decrease and LOS increase (up to 10 cm, blue color). The ascending and descending displacement time series for points in the epicentral area show initially rapidly and then slowly growing and decaying signals, respectively (Figure 2c). We therefore consider two time periods characterized by di fferent displacement patterns, from 17 November 2017 to 10 June 2018 (time period 1) and from 10 June 2018 to February 2020 (time period 2). We consider four di fferent areas (Figure 2a,b). In addition to the area used for studying viscoelastic relaxation (area 1), we consider two aftershock areas (areas 2 and 3) and an area to investigate afterslip (area 4).

Black dashed rectangle in (**a**), (**b**): coseismic fault. Black corners: displacement areas. Black solid square: reference point (used through the whole paper except for aftershock sequence 1 and 2). Black dot: upper edge of fault. Black triangle: two points to show displacement time series.
