Norway recently released the InSAR Norway portal, a web mapping application where users can see Interferometric Synthetic Aperture Radar (also known as InSAR) data showing areas where the ground is either moving up, known as uplift, or down, known as subsidence (see: Mapping Where Norway is Moving). Data from InSAR Norway has helped the Geological Survey of Norway learn where there are areas of significant ground movement in both natural and urban areas of Norway.
Osmundneset
The Hyefjorden (also called Hyenfjord) is a 14 km long fjord arm of the Nordfjord. Found on the east side of Hyenfjord, the mountainside of Osmundneset was found through analyzing the InSAR data to be highly fractured. An area about one kilometer long is currently moving at the rate of 0.5 centimeters per year.
Rolla Island
Rolla is an island in Troms, Norway that is roughly 106 kilometers in area. Brustinden at the southern part of the island is currently experiencing ground movement at the rate of around 2 cm/year.
Bjørvika
Bjørvika is an area in Oslo situated in an inlet in the inner Oslofjord. Bjørvika has been transforming from a container port with urban redevelopment. Analysis of InSAR data between 2009 and 2018 shows that the area is experiencing one centimeter per year of subsidence.
