European Ground Motion Service (EGMS) has significantly improved the ability to monitor and study geohazards using InSAR (satellite interferometry) data since its products became available for download in mid-2021. 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) image processing, making ground displacement monitoring accessible to a wider range of users. EGMS provides millimetre-accurate measurements, which are available for download via the EGMS platform. EGMSdelivers full-resolution velocity and displacement time series for both ascending and descending satellite orbits (L2a product), aligned with the GNSS reference network within a common reference frame (L2b product), and computed displacement vectors in the vertical and E-W directions (L3 products), with a spatial resolution of 100 x 100 meter.
In this session, we welcome contributions that use EGMS data to monitor and analyse different kinds of geohazards. Topics of interest include subsidence, slow-moving landslides, sinkholes, groundwater and hydrocarbon exploitation, gas storage activities, mining impacts, volcanic activity, and many more. Or studies that transform EGMS into analysis ready products for 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 for improved 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.
