A huge chunk of a glacier in the Swiss Alps broke off on Wednesday afternoon, causing a deluge of ice, mud and rock to bury part of a mountain village evacuated earlier this month due to the risk of a rockslide,

The Birch Glacier above the village of Blatten collapsed and caused a landslide that has buried most of the village. Authorities had evacuated residents earlier this month, but one person is missing.

A huge mass of rock and ice from a glacier thundered down a Swiss mountainside on Wednesday, sending plumes of dust skyward and coating with mud nearly all of an Alpine village that authorities had evacuated earlier this month as a precaution.
