Images reveal the collapse of a rock and a glacier at the border between Nepal and Tibet, which is believed to have preceded the catastrophic floods in the region.
Rescue teams are on the ground searching for missing people after the floods that devastated that border area between Nepal and China.
Scientists are analyzing satellite images to try to identify the causes of the catastrophe and understand what may have triggered the collapse.
The analysis of the images also allows for assessing the total extent of the devastation caused by the floods.
