Ground Motion Examples from the European Ground Motion Service

The Copernicus European Ground Motion Service (EGMS) provides consistent, regular, standardised, harmonised and reliable information regarding natural and anthropogenic ground motion phenomena over the Copernicus Participating States and across national borders, with millimetre accuracy. The EGMS is based on the multitemporal interferometric analysis of Sentinel-l radar images at full resolution. Global navigation satellite systems (GNSS) data are used to calibrate the interferometric measurements. EGMS provides an unprecedent opportunity to study geohazards and human-induced deformation over Europe, such as slow-moving landslides, natural subsidence or due to groundwater exploitation or underground mining activities, volcanic unrests and many other phenomena. This paper offers a first look at the products distributed by EGMS through relevant case studies in different environmental contexts of Europe.
