The ground expands and contracts with the seasons, due to changes in temperature and moisture. Buildings, bridges, roads and railways shift and settle due to the poor ground conditions.
Mountainsides can creep slowly and silently downwards for hundreds or thousands of years before collapsing catastrophically. Many of these movements are infinitesimal: only millimetres or centimetres each year. Nonetheless, the cumulative effect of these movements can be disastrous.
In cooperation with NORUT, the Geological Survey of Norway (NGU), the Norwegian Water Resources and Energy Directorate (NVE) and the Norwegian Space Centre have now launched the Norwegian Ground Motion Service, InSAR Norway.
Using images acquired every six days by the European Copernicus Programme Sentinel-1a and b satellites, we can now measure and continuously monitor all movements to within one millimetre per year at more than two billion locations across Norway.
The InSAR mapping service is open and free to everyone: government, industry and the general public.
