摘要：An inland earthquake with a moment magnitude of 7.3 occurred in western Iran / eastern Iraq on November 12, 2017. Applying an interferometric SAR (InSAR) analysis using ALOS-2 SAR data to the earthquake, we detected the crustal deformation in the northwestern part of the Zagros orogenic belt. We successfully obtained quasi-up-down and quasi-east-west displacement components by combining two sets of InSAR data. The results show that uplift occurred in the western part of the source region with ~90 cm at most, while in the east subsidence occurred with ~30 cm at most. Most of the source region moved westward with ~50 cm at most. Our preferred fault model shows that the observations can be accounted for by a nearly pure reverse fault motion with a slight dextral motion on a low-angle fault plane dipping northeast.
