This paper describes a very dramatic rate of landscape change that is both scientifically notable across the geoscience community, and of general interest to the public. The key messages can be communicated in a very accessible way, and the satellite imagery associated with the analysis clearly show the high impact changes to the valley.
Short summary
Following the detachment of the 130 × 106 m3 Sedongpu Glacier (south-eastern Tibet) in 2018, the Sedongpu Valley underwent massive large-volume landscape changes. An enormous volume of in total around 330 × 106 m3 was rapidly eroded, forming a new canyon of up to 300 m depth, 1 km width, and almost 4 km length. Such consequences of glacier change in mountains have so far not been considered at this magnitude and speed.
