Advancing our understanding of these hidden processes is essential for improving seismic and tsunami hazard assessment—especially in regions that are otherwise difficult to study directly.

Understanding these systems is critical. For such reason I’m working on a project aiming to monitor subduction slip behavior using remote seismological techniques. By analyzing teleseismic signals, we investigate subtle precursory phases and slow slip phenomena.

It involved the @universityofleeds.bsky.social, Università degli Studi di Padova, İstanbul Teknik Üniversitesi, @ingvterremoti.bsky.social and the European Center for Geodynamics and Seismology

It has been conducted in collaboration with @rosalialobue.bsky.social, Brandon VanderBeek, Manuele Faccenda, Judith Confal, Seda Yolsal-Çevikbilen, Tuna Eken, Ceyhun Erman, Paola Baccheschi and Silvia Pondrelli.

The new anisotropic 3D tomography model provides:

🟢 An updated view of major slabs (Alboran, Apennines, Alps, Dinarides, Carpathians, Hellenic)
🟢 Clear imaging of slab windows and back-arc basin dynamics
🟢 Detailed anisotropic patterns tracing mantle flow and tectonic evolution

Both works represent important steps forward, each shedding light on different facets of the volcano’s internal workings. And there's more to come: other studies are currently in preparation.

📍 The second study, led by PhD student Gianmarco Del Piccolo, identifies a pressurized magma storage system within a radial dike network located between 6 and 16 km depth—a configuration that could play a key role in Etna’s eruptive behavior.

Anisotropy helps trace geological features and offer new insight into how tectonic deformation and volcanic processes interact in this complex setting.

📍 The first study, led by Dr @rosalialobue.bsky.social , presents the first-ever P-wave anisotropic tomography based on local earthquakes recorded around Etna.
It provides high-resolution 3D images of both isotropic and anisotropic seismic structures beneath the #volcano.

🔴 L' #Etna ha generato un flusso piroclastico dal Cratere di Sud-Est, senza superare la Valle del Leone.
In corso fontana di lava, tremore e attività infrasonica molto elevati.
Nessuna deformazione significativa rilevata.
