چکیده مقاله:
An earthquake of seismic moment magnitude (Mw)6.1 occurred in northern Iran on April 5th, 2017. In this research, we employed differential interferometric synthetic aperture radar (D-InSAR) technology and Sentinel-1A(S-1A)/IW radar satellite to study the preseismic, coseismic and postseismic deformation of this event. Coseismic surface deformation measurements derived from InSAR analysis revealed a sharp uplifting of ~12 cm resulted from overthrusting and right-lateral strike-slip and the rupture process of the hanging wall in the east southwestward onto the footwall. In this work we discuss about many evidences which support previous hypotheses of motion mechanisms of the Kopeh Dagh region in northeastern Iran that has accommodated the deformation due to the collision between Arabia and Eurasia
