Differential Interferogram of the Lefkada 17 November 2015 Earthquake

On the 17th of November 2015, an earthquake of Mw 6.4 hit the western Greek island of Lefkada, located in Ionian Sea, an area that is well known for its active tectonics. A second earthquake of Mw 5.0 successively followed. These events induced rock falls and landslides having as consequences two life losses and extensive damages to roads and buildings.
Shortly after the events, BEYOND acquired a set of Sentinel-1 TOPSAR scenes, one before and one after the event. The images were combined to form an interferogram that depicts ground deformation due to the earthquake events.
The fringes of the preliminary interferometric results, which are under further elaboration, reveal ground deformation of the order of ~20cm along the Line of Sight at the western part of Lefkada Island. As smaller deformation field is also apparent at the northern part of Cephalonia Island.
