InSAR technology is one of the powerful tool to measure deformation and/or deposition on the ground surface. In addition to that the mass movement can be monitored using Interferometric Synthetic Aperture Radar (InSAR) techniques. The earthquake that occurred on November 12, 2017 in South of Halabjah (Iraq) the magnitude of 7.2 caused 350 people to lose their lives and more than 2,500 people were injured. The aim of this study is to measure the deformation due to the earthquake using “Interferometric Wide Swath”, which is one of the four display types of Sentinel 1 data. In order to carry out this process, two type of data sets were used which are SRTM data and Sentinel 1 images acquired on November 7 and 19, 2017. In this study, VV polarization with C band were used generate interferogram. During the study, SNAP 5.0 free image analysis and processing software by ESA. According to obtained results, minimum and maximum surface displacement were acquired as -0.45 and 0.49 meters. When comparing the results with existing fault lines, these are appropriate for the tectonic structures. Using InSAR technologies with open source software and free data, it is possible to produce displacement maps just after the earthquake.

Excellent publication paper realted for use InSAR technology on sample earthquake in Iraq. Turkish collegues has long expirience in predict and follow quake induced by tectonic move from Anadolia fault, that expirience can be so powerful in prediction future earhquake to make less victim and infrastructure dissaster.
