Satelite SAR Interferometry in monitoring the Zagreb 2020 Earthquake Threats to the Power Grid at Medvednica Mountain

The practical application of satellite interferometric SAR images for determining the vertical displacement of the soil after a strong earthquake in Zagreb in 2020 is presented. The area affected by the terrain displacements was compared with the tracks of transmission lines for a rapid assessment of their endangering and placing them properly on the list of priorities for in-situ damage checking. In addition to the possibility of using open source satellite imagery, such as ESA Copernicus, it is proposed to use dedicated commercial fine time resolution satellite imagery that can be used operationally during earthquake rescue and remediation actions.
