Monitoring deformation in active volcanic areas has always been of great interest, but remote sensing data has significantly increased the capability of acquiring more measurements at larger spatial scale and at relatively low cost.

Stromboli, one of the three active volcanoes in Italy, is around 3 km high with at least 2 km to be below the sea level and showing an eruptive persistent activity since almost 200,000 years. As a stratovolcano, the relatively high pressure of the gases ejects basaltic lava and its products from a few tens to hundreds of meters into the air. Many significant explosions and lava flows have been recorded in the last 50 years, the most recent events occurring on November 10 and 16, 2020. From the last one, a dense ash cloud was produced around 1 km high above the volcano’s summit and the pyroclastic current reached rapidly the coastline, expanding on the sea surface for about 200 m.

In this webinar, we will take Stromboli as an example to show you how to use Sentinel-1 data and apply the Differential Synthetic Aperture Radar Interferometry (DInSAR) technique to monitor volcanos and their activity. We will access the RUS environment to download, process, analyse and visualize the free data acquired by the Copernicus satellites.
