Abstract. Beginning in December 2020, a series of small-to-medium, torrent-like pulses commenced upon a historic debris cone located within the Nupchu valley, Kanchenjunga Conservation Area (KCA), Nepal. Sometime between 16 and 21 August 2022 a comparatively large ice-debris avalanche event occurred, covering an area of 0.6 km2 with a total estimated volume of order 106 m3. Changing cryospheric conditions throughout the region suggest that the installation of preventative floodwater diversion mechanisms for vulnerable villages is warranted, improved reporting mechanisms to authorities, and early warning systems. More systematic monitoring via remote sensing platforms and hazard mapping by scientists is also indicated.
