Earthquakes, one of the biggest natural disasters, affect the regions to which it occurs to a high degree. Determining the mechanisms of the earthquake that occurred in the light of this information is very important for both the region and the subsequent earthquakes. Interferometric Synthetic Aperture Radar (InSAR) is a commonly used method for determining co-seismic surface deformations. Especially in areas where there is no Global Navigation Satellite System (GNSS) receiver and teleseismic data source, results can be obtained quickly and effectively with InSAR. In this study, the co-seismic surface deformation caused by the Mw 5.7 earthquake in Karlıova (Bingöl), Turkey on June 14, 2020, was determined with Sentinel-1 SLC images with different incidence angles. Since Karlıova is located in the region where North Anatolian Fault (NAF) and East Anatolian Fault (EAF) lines intersect, the information given by the earthquakes in this region is very important and carefully monitored. As the InSAR technique has not been applied to earthquakes that have Mw <6 in this region, two ascending and two descending orbits were used in the study to ensure results. In the study, the amount of displacement in the line of sight (LOS) direction was determined approximately 25–30 cm. In addition, 4 different horizontal and vertical results were obtained with the combination of ascending and descending orbits. Maximum horizontal displacement created by the earthquake was obtained as 13 cm to the East, and 15 cm to the West. Moreover, in the vertical direction, uplift up to 10 cm in the northern part of the fault and subsidence up to 10 cm in the southern part of the fault were determined. According to these results, the earthquake was determined as right strike slip fault mechanism compatible with NAF tectonic structure.
