Abstract
The study area is affected by a high magnitude earthquake event at magnitude approximately 7.3 Mw on November 12, 2017. This earthquake is covered by significant surface displacement. Sentinel-1 InSAR Interferogram was used to measure and analyze this displacement during 6 days and 24 days’ intervals on November 11–17, 2017 and October 30–November 23, 2017 before and after the occurrence of the earthquake, respectively. Derbandekhan Dam, Bamo Mountain and Diyala River are examined as a reference for the displacement of the InSAR relative measurements between the two periods of InSAR. In the Derbendekhan Dam, the area is recorded horizontal deformation toward SE direction, Bamo Mountain is recorded horizontal deformation toward SE direction and Diyala River area is recorded horizontal deformation toward SE and NW directions. While the Derbendekhan Dam area is recorded subsidence deformation, Bamo Mountain is recorded uplifted deformation and Diyala River area is recorded uplifted and subsidence deformation. Finally, the results check with geodetic observation of Derbendekhan Dam that are close to them.  
Highlights
The synthetic aperture radar interferometry technology (InSAR) is one of the powerful tools to measure deformation on the earth’s surface
Based on solutions related to seismic focal mechanism of the earthquake mainshock from several agencies compiled by the European Mediterranean Seismological Centre (EMSC), it was shown that the earthquake resulted from oblique-thrust faulting (Fig. 1)
The surface vertical and horizontal deformation resulting from the InSAR for the period (1117/11/2017) are represented by the surface vertical deformation which display a maximum uplift of 1.21 m in Bamo Mountain and a subsidence zone with a maximum fullness of 0.25 m at halabja and Derbandikhan cities (Figs. 4&5)
Summary
The synthetic aperture radar interferometry technology (InSAR) is one of the powerful tools to measure deformation on the earth’s surface. A destructive earthquake occurred on November 12, 2017, south of Halabjah city, near Iraq-Iran border This earthquake locates in the N-W Zagros Thrust-Fold Belt (ZTB-ZFB), (Fig. 1), while the Zagros Mountains are uplifting since the Late Eocene as a result of the collision between the Arabian and Eurasian plates (Mouthereau et al, 2012). As compared to other sectors of the Zagros ZTB-ZFB, the area surrounding the earthquake has underwent a relatively low level of earthquakes during the recent times (Feng et al, 2018) (Fig. 1) This earthquake studied by (Gunce and San, 2018), (Feng et al, 2018) and other authors.
