Detection of coseismic displacement in the Cyclades region

Our research interest is focused on detecting ground displacements after an exceptionally large number of earthquakes occurred in the Cyclades region. Recorded as a swarm of earthquakes clustered in one place, most of which have a magnitude between 3 and 5, and the strongest was on February 5 with a magnitude of 5.2. In the case of active seismic regions, the analysis of InSAR ground deformation data provides a valuable tool for seismic risk assessment. In addition, InSAR data can be used to assess the consequences of the earthquake and its associated events, landslides, collapses, and the area of destruction. Earth Displacement of the region Santorini is certain based InSAR time-series data from the S1A satellite of the European Space Agency. The SAR dates from ascending orbit 29 and descending orbit 129 was used. The results of the InSAR analysis in the line-of sight (LOS) direction of the satellite demonstrate displacement rates between masters and slave. SAR images span the period January - February 2025.Tectonic structures in the region where the Santorini earthquakes occurred (Aegean plate), along with the location of the Kolumbo submarine volcano are significant feature in the area. The seismic activity that developed northeast of the island Santorini was analyzed, and its implications were evaluated based on the available SAR data (January 24- March 7, 2025).
