Short summary
We analysed deformation of a moving slope along the Jinsha River from November 2015 to November 2019. The slope is 80 km downstream from the famous Baige landslide, which caused two mega floods affecting downstream communities. This slope was relatively stable for the first 3 years (2015–2018) but moved significantly in the last year (2018–2019). The deformation is linked to seasonal precipitation. If this slope continues to slide downwards, it may have similar impacts to the Baige landslide.
