In the present paper using of Sentinel-1 radar images to investigate landslide activity in the mountain cluster of the Big Sochi area with the help of satellite radar interferometry methods (InSAR) is discussed. We present the InSAR landslide inventory map based on Sentinel-1 acquisitions from ascending and descending orbits for the time period 2015–2016 as well as ALOS PALSAR acquisitions from ascending orbit for 2007–2010. The InSAR landslide inventory was put together with the landslide risk assessment map of the Krasnaya Polyana region derived from ground and satellite optical data. For interferometric processing, we used DInSAR and PS-InSAR techniques within the free SNAP and StaMPS/MTI software as well as SBAS technique within ENVI SARscape. It was found that integration of results of different methods of InSAR processing makes it possible to recognize active, temporary active and dormant landslides as well as to investigate dynamics of their movements. Time series of displacements for several active landslides detected from both ascending and descending tracks are presented. The analysis of the InSAR time series of displacements for the case of the landslide in the extreme park Rosa Khutor showed that deforestation and construction of sports facilities had triggered landslide activity in the ancient landslide basin.
