Post-Seismic Surface Deformation Analysis in Boeotia, Greece Using Differential Interferometry Techniques

Source: NV5 Geospatial Software
Following a 4.0 magnitude earthquake in Boeotia, Greece, on December 2, 2020, a team of scientists from Harokopio University of Athens, led by Professor Issaak Paracharidis, conducted a comprehensive study to understand the surface deformation caused by the earthquake. Utilizing dual-polarized Sentinel-1 SAR satellite data, the team employed Differential Synthetic Aperture Radar Interferometry (DInSAR) techniques to measure ground displacement. By comparing pre- and post-earthquake SAR datasets, captured on November 11 and December 12, 2020, respectively, they generated line-of-sight (LOS) displacement maps. These maps provided detailed insights into vertical and horizontal ground movement, revealing significant subsidence and minor east-west displacement in the affected area, which includes a solar panel campus and a factory. The results were further analyzed and visualized in a GIS environment, enhancing the understanding of ground deformation patterns and potential impacts on infrastructure.
