Rapid Landslide Detection with Sentinel-1

During this webinar, we will employ RUS to learn how to detect rapid landslides. We will analyse the Fagraskógarfjall landslide that occurred in western Iceland in July 2018. 

We will use Sentinel-1 products to detect and map the extent of the landslide. We will show you how to access the RUS Service and how to download, process, analyse and visualize thefree data acquired by the Copernicus satellites.


Landslides occur in a variety of environments and can be categorized based on the type of movement and they type of material involved. They are common in areas of steep topography and can be triggered by both natural processes and human activities. Landslides can lead to damage of infrastructure or blocking of watercourses, and in the worst cases in loss of life.

The primary driving force for a landslide to occur is gravity, but there are other factors that affect the slope stability as well. In many cases, a landslide is triggered by a specificevent, such as a heavy rainfall or an earthquake.

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. This large landslide occurred on a remote part of Iceland on July 7th, 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, we can stabilize the slope or evacuate the areas that could be affected. SAR data and techniques allow us to remotelyidentify and monitor potential landslides before the main failure occurs, at a low cost, complementing other ground-based techniques.
