                                                    The village of Blatten has stood for centuries, then in seconds it was gone.

Scientists monitoring the Nesthorn mountain above the village in recent weeks saw that parts of it had begun to crumble, and fall on to the Birch glacier, putting enormous pressure on the ice.

Small rock and ice slides had begun to come down, and the village’s 300 residents, and even their livestock, were evacuated for their own safety. But everyone hoped the unstable rock would disperse incrementally over a few weeks, and that after that everyone could go home.

On Wednesday afternoon, that hope was dashed.
