Chalki ground displacement

Thanks to Europe’s environmental Copernicus programme and the Sentinel-1 mission, the first Europe-wide subsidence and soil movement analysis service is available to the public. Based on radar data from Copernicus Sentinel-1 satellite mission, the European Ground Motion Service provides information on the motion of land, structures and infrastructure in Copernicus Participating States. The service gives users reliable information on ground motion at a local, regional or national scale.

For example, this graph shows the rate of ground displacement around the village of Chalki, near Larissa in Greece – between 2016 and 2021 the ground subsided by a total of 21.55 cm. This subsidence is largely a result of groundwater extraction.
