This project aims at demonstrating that Distributed Acoustic Sensing technology is able to improve monitoring of volcanoes and provide insight in proceses and structure that we cannot access with conventional instruments. We deployed in 2018 and in 2019 DAS (Distributed Acoustic Sensors) cables and conventional sensors from the GIPP (trillium sensors and cubes) at the summital area of Etna volcano. Simultaneously, we also recorded distributed in Telecommunication fibre lines in villages on the slope if the volcano, and also under the sea from Catania harbour.
