Abstract: Based on the results of processing an interferometric pair of PALSAR-2 L-band synthetic aperture radar (SAR) images taken over the territory of the Bureya landslide in May 2019 and May 2020 from the ALOS-2 satellite, a new unstable surface region has been discovered. The average monthly rate of soil displacement was estimated to be up to 1 cm/month along the slope surface at the site of the formation of a new scarp. It is noted that the materials of interferometric processing of archival data did not previously reveal any movements of the slope surface in this place. The most probable reason for the activation of the landslide process in the new area is named: a violation of stability as a result of the descent in December 2018 of the underlying landslide body.
