Mt. Etna Catalogue Earthquake Complete Moment Tensor

We computed the full seismic moment tensor of 14 earthquakes (3.5 <ML ≤ 4.8) that occurred in the Etna area in the period October 2018 to December 2020 and were recorded by the seismic broadband network managed by Osservatorio Etneo (INGV-OE). The focal solutions computed are here reported and compared with that obtained using the standard first arrival polarities method, based on the assumption of a double couple source type. The full seismic moment tensor computation allows for a complete definition of the earthquake source, through the inversion of the seismic waveforms. It permits the calculation of the Seismic Moment, the Double Couple component (DC) which allows identifying the nodal planes of the focal mechanism, and the non-DC components as Compensated Linear Vector Dipole (CLVD) and volumetric (ISO). In a volcanic environment, such as Etna, the computation of the non-DC components can provide useful information for a comprehensive study of the source, accounting also for the role of magma in the generation of earthquakes (e.g. Saraò et al., 2001; 2010; 2016).
