European Ground Motion Service (EGMS) has significantly improved the ability to monitor and analyse geohazards using InSAR (satellite interferometry) data since its products became available for downloading in mid-2022. These interferometric products are provided by the Copernicus Land Monitoring Service (CLMS) under the responsibility of the European Environment Agency (EEA). EGMS overcomes the long-standing challenge of complex SAR (Synthetic Aperture Radar) images processing, making ground displacement monitoring accessible to a wider range of users. EGMS provides millimetre-accurate measurements, which are available for downloading via the EGMS platform. EGMS delivers full-resolution velocity and displacement time series for both ascending and descending satellite orbits (Level 2a), aligned with the GNSS (Global Navigation Satellite System) reference network within a common reference frame (Level 2b), and computed displacement vectors in the vertical and E-W directions (Level 3), with a spatial resolution of 100 x 100 m.
In this session, we welcome contributions that use EGMS data to monitor and investigate different kinds of geohazards. Topics of interest include subsidence, slow-moving landslides, sinkholes, groundwater and hydrocarbon exploitation, Underground Gas Storage (UGS) activities, mining impacts, volcanic activity, and many more. We also welcome studies transforming EGMS data into analysis ready products for several topics, e.g, coastal studies or climate change estimations. We also encourage studies that explore the impact of these geohazards on critical infrastructure and buildings, or that integrate EGMS data with other methods to improve geohazard assessment. We aim to highlight the versatility and value of EGMS data in understanding and mitigating the risks associated with natural and man-made induced geohazards. Contributions demonstrating innovative applications, cross-disciplinary approaches and case studies with practical implications are particularly welcome.
