Assessment of the Bureya River Landslide Reactivation Using the Persistent Scatterer Interferometry
The results from the Bureya landslide study by the method of persistent scatterers using multi-temporal synthetic aperture radar (SAR) data for the years of 2019–2020 are presented. The analysis of coherence of the Sentinel-1B and ALOS-2 PALSAR-2 data at various sensing geometry and different polari...

| description | The results from the Bureya landslide study by the method of persistent scatterers using multi-temporal synthetic aperture radar (SAR) data for the years of 2019–2020 are presented. The analysis of coherence of the Sentinel-1B and ALOS-2 PALSAR-2 data at various sensing geometry and different polarizations has shown that temporal decorrelation of radar backscattering takes place over most of the surface of rupture. The difference in the dynamics of deformations for the western and eastern above-water parts of the landslide in the river has been found. A chaotic change in the surface structure due to rockfalls and small landslides, as well as a displacement of about 10 mm in the lower northeastern part of the surface of rupture have been revealed. |
