A small village is "under rubble" after a glacier partially collapsed in the Swiss Alps this week, causing a mudslide. An official stated that 90% of the village of Blatten, with an estimated population of 300 people, is covered in debris and ice from the May 28 event, Reuters reported.

On Wednesday, a landslide from the mountain side of Birch Glacier -- located in the Lötschental valley in northern Switzerland -- flattened homes in the Alpine town of Blatten after a large chunk of the glacier broke off, Bethan Davies, a professor of glaciology at Newcastle University in the U.K., told ABC News.
