A flash flood swept through Nepal's Rasuwa district on Wednesday, leaving at least 157 people dead and hundreds more missing [8, 10].
The disaster highlights the increasing vulnerability of Himalayan communities to extreme weather and the unpredictable nature of glacial melt in a warming climate.
Emergency crews are searching for missing persons across the Nepal-China border area. Reports on the death toll vary as the situation evolves. While some early reports cited eight [6, 7] or nine deaths [4], later estimates suggest the toll has reached 95 [1] or as many as 157 [8].
The scale of the disappearance is significant, with over 400 people reported missing [2]. This includes over 100 Indian tourists [3, 5] and 24 Canadians [9].
Authorities have not confirmed the exact trigger of the flood wave. However, experts suggest the event may have been a glacial-lake outburst flood, known as a GLOF [3]. These occur when a dam containing a glacial lake fails, releasing a massive volume of water downstream, often with little warning.
Local geography makes the Rasuwa district particularly susceptible to such events. Rapid glacier melt, driven by rising temperatures, creates unstable lakes that can burst during seismic activity or extreme melt cycles [3].
Rescue operations continue in the rugged terrain near the Tibet border. Officials said they fear the death toll will rise as more remote areas are reached [6].

This event underscores the growing risk of Glacial Lake Outburst Floods (GLOFs) in the Himalayas. As climate change accelerates glacier melt, the number of unstable glacial lakes increases, posing a systemic threat to both local residents and the tourism industry in high-altitude border regions.
