DInSAR Analysis and Analytical Modeling of Mount Etna Displacements: The December 2018 Volcano‐Tectonic Crisis

A dike intrusion during the December 2018 eruption of Mount Etna triggered the opening of eruptive fissures and activated shallow volcano-tectonic faults, including the Fiandaca Fault, which experienced the strongest seismic event (ML 4.8) on December 26. The study combines DInSAR measurements from Sentinel-1 satellite data with analytical modeling to reveal that fault activation was a response to deformations caused by magma injection. This finding sheds light on the complex interactions between magma intrusion and tectonic structures, offering insights into the dynamics of volcanic crises.
