Coseismic ground deformation of the November 26, 2019 M6.4 earthquake of Durrës, Albania estimated by DInSAR
Keywords:Albania, earthquake, Sentinel-1, ground deformation, remote sensing
An earthquake of magnitude 6.4 occurred in Albania on November 26, 2019 at 03:54:12 (local time). The epicenterof the earthquake was about20 km from the coastal city of Durrës. The purpose of this study is toestimate the ground deformation associated with thisearthquakeby Differential Interferometric Synthetic Aperture Radar (DInSAR) technique. A differential interferogram was formed using the two Sentinel-1 Single Look Complex (SLC) images. The flattened and filtered differential interferogram was unwrapped and converted to ground displacement. The results indicatethat in the area close tothe epicentrethe ground is uplifted at a maximum of 8 cm along the radar line-of-sight (LOS). Progressively smaller ground uplift isdetected in an area of about 10-15 km around the major uplift zone. The earthquake could be related with under thrustingof Adria microplate or fault processes within the under thrustedAdria microplate itself. Further monitoring by satellite imagery is needed to investigate the post-seismic ground deformation in the area.
