Moment Tensor Etna Earthquakes

We computed the full seismic moment tensor of the earthquakes (3.5<ML ≤4.8) that occurred in the Etna area in the period May 2008 to December 2020, recorded by the seismic broadband network managed by the INGV - Osservatorio Etneo. The full seismic moment tensor computation, through the inversion of the seismic waveforms, allows for a comprehensive definition of an earthquake source. In particular, the moment tensor is directly related to the earthquake fault orientation and kinematics, while the derived moment magnitude, Mw, is the most reliable quantity for measuring the size of an earthquake. In addition, the source tensor can provide information on the decomposition into isotropic (ISO), double-couple (DC) and compensated linear vector dipole (CLVD) components. This distinction is a tool for classifying and physically interpreting seismic sources. Indeed, although most tectonic earthquakes are dominated by shear deformation in narrow area (DC component of the tensor), in volcanic and geothermal areas, other processes, such as the migration of magmatic and hydrothermal fluids or rupture on non-planar faults, can produce earthquakes with significant non-double-couple components. (e.g. Minson et al. 2007; Saraò et al., 2010; 2016).
