Volcano Monitoring with Sentinel-1

During this webinar, you will learn how to use Sentinel-1 data and apply the Differential Synthetic Aperture Radar Interferometry (DInSAR) technique, in order to monitor volcanos and their activity.

We will also show you how to access the RUS Service and how to download, process, analyse and visualize the free data acquired by the Copernicus satellites.


Background

In this webinar, we will focus on the Stromboli volcano, the northernmost island of the eight of the Aeolian Archipelago, in the Southern Tyrrhenian Sea, and one of the three active volcanoes in Italy. It is a stratovolcano of approximately 3 km elevation, at least 2 km of which below the sea level.

Its persistent eruptive activity started almost 200,000 years ago and due to this “Strombolian-type activity”, the island carries the nickname “Lighthouse of the Mediterranean”. The relatively high pressure of the gases ejects basaltic lava and its products to hundreds of meters in the air.

Many significant explosions and lava flows have been recorded during the last 50 years, with the most recent events on July 3, 2019 and on November 10 and 16, 2020. During the last one, a dense ash cloud elevated for approximately 1 km above the volcano's summit and the subsequent pyroclastic flow reached rapidly the coastline, expanding on the sea surface for circa 200 m.

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