Short summary
On 22 March 2021, a ~ 50 Mm 3 ice-rock avalanche occurred from 6500 m a.s.l. in the Sedongpu basin, southeastern Tibet. It caused temporary blockage of the Yarlung Tsangpo river, a major tributary of the Brahmaputra. We utilize field investigations, high-resolution satellite imagery, seismic records, and meteorological data to analyse the evolution of the 2021 event and its impact, discuss potential drivers, and briefly reflect on implications for the sustainable development of the region.
