The Fagraskógarfjall landslide was likely triggered by the large volume of rainfall that Iceland received during the 2018 summer. It was one of the largest recorded landslides and has a volume of around 10-20 million m3. It occurred on a remote part of Iceland on 7 July 2018 and based on former satellite data, the hillside was known for its instabilities since 2015. By detecting and monitoring such movements before a critical failure, it is possible to stabilize the slope or evacuate the areas that could be affected.

This webinar will focus on the detection of rapid landslides, using SAR data processed through the RUS environment. SAR data and techniques indeed allow us to remotely identify and monitor potential landslides before the main failure occurs, at a low cost, contrary to other ground-based techniques. Relying on Sentinel-1 products to detect and map its extent, we will analyse the Fagraskógarfjall landslide. You will learn how to access the RUS Service and how to download, process, analyse and visualize the free data acquired by the Copernicus satellites.

You can replay this webinar through our RUS Copernicus Training channel available on Youtube.

You can also retrieve the corresponding training support in the Learn by yourself section of the RUS portal.
