Eight people are missing after a massive landslide in Bondo, near the Italian border in the south of Switzerland.
On Wednesday August 23rd a huge chunk broke off the side of a mountain in Bondo, in the southern Swiss Alps, at speeds of more than 250km/h. It is suspected that the resulting landslide swept away eight hikers.
A second landslide followed on Friday August 25th, causing rescuers to abandon the search for the missing people, and a third landslide on August 31st poured more rubble into the beleaguered village.

European Space Imaging photographed the scene from space on August 27th and September 5th, using the very high resolution satellites WorldView-3 and WorldView-4.
It can clearly been seen that mud and rubble from the two landslides have destroyed houses and roads.

Understanding ONA in Satellite Imagery: What is Off Nadir Angle and What Is It Used For?
Off Nadir Angle (ONA) plays a crucial role in the quality of optical satellite imagery. It influences its resolution and clarity, decides the visibility of features, and makes it easier or harder to identify objects. Moreover, ONA is used to create stereo imagery and 3D models of the Earth’s surface. Read on to learn more.
