Sentinel-1 sees Mocoa landslide
04 April 2017
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.

Top story on Copernicus
02 February 2018
After being put through its paces to make sure it is fit for life in orbit around Earth, the Copernicus Sentinel-3B satellite is ready to be packed up and shipped to Russia for liftoff.
Its twin, Sentinel-3A, has been in orbit since February 2016, systematically measuring our oceans, land, ice and atmosphere. The information feeds a range of practical applications and is used for monitoring and understanding large-scale global dynamics.
