“…This was done with the assumption that the horizontal movement is negligible. The map of the European Ground Motion Service (Costantini et al., 2021) gives some indication of horizontal movement in the area, but all the points with East‐West movement appear to be in the vicinity of founded structures. Manually checked points on top of sportfields do not show significant East‐West movement.…”

Over half a billion people live in coastal plains and deltas threatened by anthropogenically induced subsidence, and this number is expected to increase in the foreseeable future (Neumann et al., 2015;Schmidt, 2015). Many anthropogenic subsurface activities in coastal areas and delta plains result in subsidence, thereby amplifying relative sea-level rise and flood risks, inflicting damage to infrastructure, and overall, reducing the viability of these low-lying areas (

“…Some typical examples are the parallel small baseline subset (P-SBAS) processing chain [52][53][54], LiCSBAS [55][56][57], a tool for multitemporal SAR interferometry with big volumes of Sentinel-1 data and SNAPPING [58], a surface displacements mapping tool using Sentinel-1 data that operates on the GEP platform. Finally, the European Ground Motion Service (EGMS) [59,60] provides a unique product of InSAR ground displacements in Europe with Sentinel-1 data.…”

The island of Cyprus is characterised by a complex geological environment as it overlies a boundary zone of three tectonic plates, leading to high seismicity and intensive tectonism. It consists highly of Neogene marls, exhibiting serious geotechnical problems due to their high content of clay minerals. Along with strong, destructive earthquakes, various geohazards have been identified in Cyprus, including landslides, swelling/shrinking phenomena and land subsidence etc. Pedoulas is a village in Cyprus experiencing ground deformation due to landslide phenomena. Conversely, Pyrgos and Parekklisia villages in Limassol, Cyprus are experiencing a long-term swelling/shrinking phenomenon. To further investigate this surface deformation, a time-series InSAR analysis of Sentinel-1 SLC images of ascending satellite passes was performed, with a parallelised version of PSI (Persistent Scatterers Interferometry), along with field investigation, for the time period of 2016 to 2021. Negative vertical displacements with maximum rates of −10 mm/y, were identified in Pedoulas village, while positive vertical displacements with a maximum rate of 10 mm/y, dominated in Pyrgos and Parekklisia villages. The analysis of precipitation data from 2017 to 2021, presented a correlation between annual fluctuations in precipitation in the affected areas and changes in the InSAR time-series deformation trends. In Pedoulas village, landslide movements sped up during spring and summer, when the infiltration of waste water in the ground intensified due to the increase in the tourist population. In Pyrgos-Parekklisia villages, higher positive deformation rates were identified in winter months, while during summer, when the formations dried out, uplifting phenomena stopped evolving. The integration of InSAR displacements with field investigation provided validation of the observed ground failures and added valuable insights into the driving mechanisms of the deformation phenomena. Finally, the assessment of the impact of the triggering factor in the evolution of the deformation phenomena, can serve as a valuable tool for risk mitigation.

“…The rates we have derived can be used to train machine learning algorithms to identify natural subsidence in large InSAR datasets. For example, the European Ground Motion Service (EGMS [26]) con-tains over 6 million measurement points for the UK alone, manual analysis of so many points and their time series is not possible, therefore having training datasets which characterise the motion characteristics for subsidence phenomena is essential to better use these new data.…”

Sixteen of the world’s largest cities, with populations of over 10 Million, are located within 100 km of the coast (as are sixteen European cities, with populations of over 1 Million). The need to understand the contribution that the lowering of the ground surface, through natural geological phenomena, can make to estimates of relative sea level change is especially relevant to these lowland areas, which are usually the most geologically susceptible to subsidence. In this work, the methodology developed within the SubCoast EC-FP7 project was exploited to create a combined natural sub-sidence potential percentage change value for each lithology of the OneGeology dataset for Europe. Calibration of potential volume changes against ground motion statistics extracted from interpreted Persistent Scatterer Interferometry (PSI) and geohazard mapping datasets allowed for the deriva-tion of potential ground motion rates for the coastline of Europe. By utilising this subsidence po-tential methodology and combining it with the British Geological Survey (BGS) geology (superficial and bedrock) 1:50,000 scale dataset, a nation-wide dataset of potential natural subsidence rates was produced for Great Britain, providing information for all lithologies of the country. By incorporating the most current and up-to-date PSI data, the potential subsidence rates could be re-calculated, and a more detailed, calibrated polygon dataset could be created in the future. SubCoast was a collab-orative research project funded by the EU, the aim of which was to assess the combined impact of sea level rise and coastal subsidence as measured with satellite radar interferometry.
