The analysis presented here exploits a large active seismic database that fully covers the area under study. We observe that scattering effects dominate over intrinsic attenuation, suggesting that the region is very heterogeneous. Comparison with analyses conducted at other volcanoes reveals that the Mt Etna region is characterized by high intrinsic attenuation, resulting from the presence of large volcanoclastic deposits at shallow depth. The 2-D distributions of intrinsic and scattering anomalies show the presence of regions characterized by high and low attenuation effects, corresponding to several tectonic and volcanic features. In particular, we identify a high attenuation region in the SW sector of the Mt Etna volcanic complex, which is correlated with high seismicity rates and volcanism. This work supports the hypothesis of a link between the dynamics of the SW flank and the recharge of the volcano in the last decades, occurring under the summit crater and, secondarily, the upper South rift zone. info:eu-repo/grantAgreement/EC/H2020/798480/EU/State of unrest of active VOLCANOes through advanced seismic WAVES analysis - An application to eruption forecast modelling/VOLCANOWAVES This project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 798480-VOLCANOWAVES info:eu-repo/grantAgreement/ES/MINECO/TEC2015-68752-R1 info:eu-repo/semantics/closedAccess by https://creativecommons.org/licenses/by/4.0/deed.es 2.574 2019 GEOCHEMISTRY & GEOPHYSICS 39 / 84 = 0.464 2019 Q2 T2 1.339 2019 Geophysics 2019 Q1 Geochemistry and Petrology 2019 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Castro-Melgar, Ignacio (orcid)0000-0001-5938-3606 Cocina, Ornella Zuccarello, Luciano Branca, Stefano Del Pezzo, Edoardo Prudencio, Janire 220, 1 (2019), 267-277 Geophys. j. int.
