Sentinel-1 radar coverage from before and after the 01 April 2017 mudslide in Mocoa, Colombia, shows the extent of movement of the disaster that claimed over 260 lives, injured hundreds more and left scores displaced.

Triggered by heavy rain, the landslide caused greatest movement (red) on top of a mountain. It then pushed mud down across the city of Mocoa (green) and crossed the nearby river.

Sentinel-1's radar ability to ‘see' through clouds, rain and in darkness makes it particularly useful for monitoring areas with frequent cloud cover. Images acquired before and after events such as floods, landslides or earthquakes offer immediate information on the extent of affected areas and support assessments of property and environmental damage.

With the Sentinel-2B satellite close to beginning its working life in orbit, this latest Copernicus satellite has linked up to Alphasat by laser, across almost 36 000 km of space, to deliver images of Earth just moments after they were captured.

The test, which was done as part of Sentinel-2B's commissioning, included capturing a strip of images from Europe to North Africa.
