Swiss officials announced over the weekend that they would halt search operations for 8 missing hikers after a massive landslide near the small village of Bondo, Switzerland. Geologists toured the source area by helicopter and determined it was unsafe to continue the search. The event is referred to as a rock avalanche by the Landslide Blog, and Professor Petley had two links to videos of the event. The first, showing the initiation of the landslide is shown below. The landslide occurred on Piz Cengalo above Bondo on August 25 and resulted in a debris flow 5 km downstream at the town.
