Shadows in optical images will deteriorate deformation measures in the pixel offset tracking method. We proposed a simple method to correct mismatches in deformation time series between Sentinel-2 and Landsat 8. We found high temperatures accelerated the landslide deformation in summers 2017/18, because rising temperatures weakened the ice strength on the sliding plane. Climate warming will result in more similar hazard chains in deglaciating mountains.

The eastern Tibetan Plateau is an ideal place to study interactions among different geomorphic drivers. We report the impacts of two 2018 landslide-lake outburst floods up to 100 km distance downstream of the Jinsha River. By using remote sensing images, we found that the 2018 floods caused many hillslopes to slump during the prolonged period afterwards. The finding could help us to obtain a holistic picture of LLF impacts and improve geomorphic models of landscape evolution.

Major mountain earthquakes often trigger numerous co-seismic landslides. Vegetation dynamics on landslides can be used to indicate post-seismic landslide activity. We used thousands of remote sensing images and possible influencing factors to uncover the spatial pattern and drivers of vegetation recovery on landslides after the great 2008 Sichuan earthquake. Detailed pattern for the entire region is revealed and three paramount influencing factors were determined.
