Quick Summary

A chunk of ice broke off from a Himalayan glacier around 8:40 a.m. Wednesday and fell 17,000 feet, triggering an ice avalanche that blocked the Lhende River before releasing a massive torrent downstream. The resulting flash floods killed at least 168 people, with many more feared dead, and devastated villages along the Bhote Koshi and Trishuli rivers in Nepal. A total of 63 American citizens are missing after being caught up in the floods while on pilgrimages to Mount Kailash. The US Geological Survey initially reported a 4.4-magnitude earthquake before determining that the seismic event was actually caused by the glacial collapse.
