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]

We present a new three‐dimensional (3D) image of attenuation beneath Mt. Etna volcano based on the coda normalization method. Mt. Etna is an ideal natural laboratory for the application of new or unconventional tomography techniques owing to high levels of seismicity spanning a wide range of epicentral distances and depths. We retrieved seismic waveforms from the database generated in the 2014 TOMO‐ETNA seismic experiment and performed a joint interpretation of tomographic and geophysical inversion models to better constrain interpretations of the volcanic structure. We compared the attenuation tomography results with seismic inversion models (two P wave seismic models and a 3D coda wave seismic attenuation model) and the literature to highlight and interpret structural elements and their impact on the volcano dynamics. We created a new image of the inner structure of Mt. Etna that will help to constrain present and future volcanic behavior. In particular, we focused on magma storage below the summit area and identified a large high‐attenuation volume that is characterized by physical properties compatible with the presence of magma and other fluids. The existence of such a large volume of magma in the shallow crust below Mt. Etna has implications for the eruptive potential of the volcano. Plain Language Summary: Mount Etna, Italy, is one of the world's most active volcanoes and presents an almost constant state of activity. To correctly interpretate potential volcanic hazards, there is a need to better understand the complex inner structure of the volcano. To this end, Mt. Etna is an ideal natural laboratory for the application of new or unconventional tomography techniques. We analyzed seismic attenuation, which measures the loss of energy of the seismic waves, to obtain a three‐dimensional attenuation model of Mt. Etna. We compared our attenuation tomography results with other geophysical data in order to interpret key structural elements and their impact on volcano dynamics. We identified a large volume below the summit area that is compatible with the presence of magma and other volcanic fluids, highlighting the continued eruptive potential of the volcano.
