GNGTS 2022 Sessione 1.3 139 Fig. 1 - Tectonic settings and historical earthquake with M>3.5 on Sulaiman Fold Thrust (SFT) belt. (a) Faults are taken from (Pezzo et al. , 2014). The dark red moment tensor is the 2015 Dajal earthquake epicenter, shown above the slip distribution. Black boxes are showing the ascending (T071) and descending (T005) tracks of Sentinel-1A. The inset shows the geographical location of the SFT belt and the relative motion (36 mm/yr) between the Indian subcontinent and the Afghan block (Ul-Hadi et al. , 2013). b) and c) Ascending and descending interferograms of the 2015 Mw 5.7 Dajal earthquake, respectively. generate the Sentinel-1A ascending (ASC071) and descending (DSC005) interferograms (Fig. 1b, c), allowing us to constrain two directions of motion. The LOS displacement is ~45 and ~50 mm due to thrust-dominated slip over a blind fault. The Dajal earthquake ruptured the base of the foreland-vergent Boundary Thrust buried under sediment from the Indus River
