Several seismic tomographic studies have been carried out to outline the intricate interplay between tectonics and magma uprising at Etna volcano. Most of these studies assume a seismically isotropic crust. Here we employ a novel methodology that accounts for the anisotropic structure of the crust. Anisotropy patterns are consistent with the Etna structural trends, unveiling the depth extent of fault segments. A high‐velocity volume, deepening toward the northwest, identifies the subducting foreland units that appear to confine a low‐velocity anomaly, interpreted as the expression of magmatic fluids within the crust. A discontinuity, likely tectonic in origin, affects the subducting units and allows magma transfer from depth to the surface. This structural configuration may explain the presence of such a very active basaltic strato‐volcano within an atypical collisional geodynamic context. Plain Language Summary: [In our study, we investigate the complex relationship between tectonics and magma ascent at Etna volcano. Unlike previous research, we consider the anisotropic nature of the crust, meaning its properties vary depending on direction. Using our innovative methodology, we have uncovered patterns aligned with Etna fault segments, revealing their depth and distribution. We have identified the presence of magma fluids within the crust and potential pathways for its uprising. Our results provides an explanation for the emplacement of the very active Etna basaltic volcano within an unusual collisional geodynamic setting.] Key Points: This study conducts the first P‐wave anisotropic tomography using local earthquakes recorded in the area of Etna volcanoThe tomography resolves three‐dimensional (3D) isotropic and anisotropic structures beneath the volcanoAnisotropy reveals geological features providing valuable insights into the interplay between tectonic deformation and volcanic activity [ABSTRACT FROM AUTHOR]

Three dimensional attenuation images of Mt Etna volcano obtained by the analysis of Q -coda from local volcano-tectonic earthquakes are presented in this work. Seismic sources are confined inside the Etna structure with a maximum focal depth of 35 km below the sea level. The space distribution of the attenuation values was calculated by using 3-D weighting functions derived by the sensitivity kernels of Pacheco & Snieders and approximated by a polynomial interpolation, represented in the maps by using a backprojection method. Data were analyzed in four bands with central frequency placed at 1.5, 3, 6 and 12 Hz, respectively. We observed a frequency dependence of Q -coda with values that range from 55 at 1.5 Hz to 218 at 12 Hz. Q -coda space distribution in the Etna area shows almost uniformity in the average attenuation in the first 35 km below the surface. The images were derived with a resolution of 5 km. We observe as one of our main conclusions that Q -coda attenuation space anomalies are correlated with the areas of highest structural heterogeneities and are distributed along the well-known tectonic structures which characterize the crust in Mt Etna region. Previous and numerous velocity and attenuation images describing the structure of Mt Etna support our main conclusion: high Q -coda volumes almost coincide with the zones marked by high velocity and relative low total attenuation for direct waves.
