Kryvyi Rih is a city in the Dnipropetrovsk region of the South-eastern part of Ukraine, the main steel industry city of Eastern Europe and a globally important center of the iron ore mining and metallurgy. The area includes technogenically affected land under geodynamic disasters risk. This article describes the use of satellite radar interferometry time series analysis and geological/geophysical data to map geodynamic risk of the Kryvyi Rih city’s central part. Long-term time series of Sentinel-1 satellite differential InSAR measurements were engaged for this purpose. Detecting and mapping the high-precision land surface movement dynamics serves as an important indicator of potential environmental vulnerability. The article presents the technique used for analysis of the time series of small displacements of the land surface and their interpretation. Geological and geophysical data are auxiliary for risk forecasting and the production of geodynamic risk maps of the study area.
