Measuring Earthquake-Induced Deformation in the South of Halabjah (Sarpol-e-Zahab) Using Sentinel-1 Data on November 12, 2017

İngilizce (OpenAlex)

Synthetic aperture radar interferometry (InSAR) technology is one of the powerful tools to measure deformation and/or deposition on the ground’s surface. In addition to this, mass movement can also be monitored using InSAR techniques. The earthquake that occurred on November 12, 2017 in the south of Halabjah with a magnitude of 7.2 caused 350 people to lose their lives, and over 2500 people were injured. The aim of this study is to measure the deformation resulting from the earthquake using the “Interferometric Wide Swath”, which is one of the four display types of Sentinel-1 data. In order to carry out this process, two types of datasets were used, SRTM data and Sentinel-1 images acquired on November 7 and 19, 2017. In this study, VV polarization with the C band was used to generate an interferogram. During the study, SNAP 5.0 free image analysis and processing software by the European Space Agency (ESA). According to the obtained results, the minimum and maximum surface displacements were −0.45 and 0.49 m. When comparing the results with faults, the results 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 earthquakes.
