Is the ground moving under Alaska's critical infrastructure?

Alaska Ground Watch tracks millimeter-scale ground subsidence and uplift at critical-infrastructure sites across Alaska using satellite InSAR — built for ports, airports, pipelines, and the agencies that keep them running.

An ADAC-Arctic project. Ground movement is derived from Sentinel-1 InSAR (processed with SBAS/ISBAS) and measured along the satellite line-of-sight relative to each area's first acquisition. Data source: Boston Geospatial.
