Abstract
|
Interferometric Synthetic Aperture Radar (InSAR) technique was applied to extract high-accuracy co-seismic deformation field of the 2017 Sarpole-Zahab earthquake. To that end, Sentinel-1A/B SAR images from three tracks were analyzed using the two-pass method. The results revealed by A072 showed a LOS-direction uplift area with a maximum deformation of ~ 85 cm. The deformation obtained from descending tracks (D006 and D079) was about 55 and 52 cm toward and away from the satellite, respectively. Also, InSAR analysis indicated some geological phenomena including landslide and surface rupture near the epicenter area. Finally, PGA distribution represented a north-south direction for rupture wave propagation.
