From InSAR Norway to a Global Ground Motion Service: Operational Monitoring for Disaster Risk Reduction

Ground movement can be measured from space by comparing satellite images taken at different times using a technique known as InSAR. The InSAR Svalbard service provides baseline information showing where and how the ground is moving, supporting geohazard management, land-use planning, and climate change adaptation, and helping assess impacts on infrastructure and human activities. While such services exist elsewhere, this is the first of its kind in the Arctic.
