英文摘要	We reveal transient surface deformation following the 2017 M(w)7.3 Sarpol Zahab (Iran) earthquake using Interferometric Synthetic Aperture Radar (InSAR) measurements. Based on the coseismic interferograms derived from the Advanced Land Observing Satellite-2 (ALOS-2) data, the preferred slip model of the earthquake has a centroid depth of 14.5 +/- 4 km and suggests that a basement fault is most likely responsible for the 2017 earthquake in the northwest Zagros fold-thrust belt zone. Two slip asperities with a maximum slip of 6 m separated by 16 km are observed in the best fitting slip model. The accumulated afterslip in the first month after the mainshock determined from the Sentinel-1 postseismic interferograms reveals a slip distribution that lies immediately updip of the coseismic slip, implying that frictional properties of the fault vary along the rupture patch. The Bamo Mount in the earthquake area was uplifted by approximately 1m during the earthquake. We suggest that local topographic growth from both seismic and aseismic faulting behaviors is common within the Zagros fold-thrust belt zone based on our findings regarding the 2017 earthquake and other significant events in the region.
