Nepal floods traced to undetected ice-rock avalanche, exposing warning gaps

Scientists attribute Nepal's Rasuwa district floods to a sudden, undetected ice-rock avalanche in the Himalayas, which conventional early-warning systems failed to catch. The event underscores the growing unpredictability of glacial hazards under climate change, raising concerns for downstream communities and infrastructure. The finding is based on post-event investigation, with the exact trigger and recurrence risk still uncertain.
