English: On 3 March 2021 Greece was affected by a series of intense earthquakes, the strongest of which hit with a magnitude of 6.3 and an epicentre near Elassona, at an estimated depth of 10 kilometres. According to media reports, nearby cities suffered infrastructural damage and walls in numerous older buildings were damaged or collapsed. As a consequence of the structural damage and due to the fear of aftershocks, which did take place on 3 and 4 March, thousands of people spent the night outside of their homes, as the authorities set up tents and outdoor meal counters. Data supplied by Copernicus satellites and services can help better understand the dynamics of earthquakes and accurate mapping of the resulting damages, allowing for an efficient response in disaster-stricken regions. This image, acquired by the Copernicus Sentinel-3 satellites on 4 March 2021, shows a cloudless view of Greece and North Macedonia, as well as parts of Republic of Türkiye, Bulgaria and Albania. After the period of record snowfalls that blanketed Southeast Europe in February, the air pressure in the region has been at a persistent high, allowing for exceptionally clear views of the region from space
