Nepal flood kills nearly 500 after early warning systems fail
A massive flood triggered by a dammed lake outburst in Tibet swept through Nepal’s Bhotekoshi and Trishuli River corridors on Wednesday, causing widespread devastation. The disaster has resulted in nearly 500 deaths, with hundreds more reported missing. The surge destroyed homes, schools, government offices, bridges, and critical infrastructure, including approximately 12 operational hydropower plants.
The catastrophe has highlighted a critical failure in early warning systems. Despite a previous agreement between Nepal and China to share water hazard data following a similar incident last year, authorities in Nepal received information only 16 minutes after the flood crossed the border. In some areas, such as Syabrubesi, the water arrived just 10 minutes after entering the country, leaving little to no time for emergency alerts to reach vulnerable communities.
Preliminary assessments suggest a landslide may have blocked the Lhendhe River upstream of Rasuwagadhi, creating a temporary lake that subsequently burst. Experts noted that such sudden glacial and landslide-induced events are increasing in the high Himalayas due to climate change.
