Is Denver sinking?
Parts of it, measurably. Across 22,918 satellite-measured grid cells in the Denver metro, the median ground motion is 1.6 mm/yr downward, the fastest-sinking cell measures 6 mm/yr, and 4.3% of measured cells exceed the 3 mm/yr "notable" threshold. Motion varies block by block — check your specific address.
How do you measure ground motion in Denver?
InSAR: radar satellites (Copernicus Sentinel-1) compare the phase of millions of radar returns across years of passes, revealing millimetre-scale vertical land motion. The data comes from peer-reviewed research (Ohenhen et al., Nature Cities 2025 and related datasets) and is screened on a ~100 m grid.
What should Denver buyers and owners do with this?
Use the free screening for the measured rates around any address. An amber or red result is context for a professional conversation — share the report with a licensed geotechnical engineer or structural surveyor. A green result means no notable motion was measured nearby; it is not a guarantee.
