Abstract The results of interferometric processing and analysis of European spaceborne synthetic aperture radar (SAR) Sentinel-1 acquired over the territory of Norilsk thermal power plant TPP-3 are presented. Radar interferograms created cover both cold season of 2019-2020 and warm season of 2020 including catastrophic event- the rupture of the tank with diesel fuel. Owing to high temporal stability of radar signals backscatter from the surface of TPP-3 territory on the time interval between repeated observations the monitoring of the stability of fuel tanks and adjacent territory using classical radar interferometry technique was conducted. It was discovered that the relative location of all four TPP-3 reservoirs and adjacent territory is stable within the 2-3 mm band on all the observation intervals. We may suppose that the fuel tank rupture was not caused by the dynamics of the study area as a consequence of permafrost thaw.
