    <description xml:lang="en" descriptionType="Abstract">We computed focal solutions of earthquakes (1.3≤ML≤4.8) recorded by the seismic network managed by the INGV, that occurred in the Mt. Etna area in the period between 2002 and 2021.</description>
    <description xml:lang="it" descriptionType="Abstract">Sono state calcolate le soluzioni focali dei terremoti (1.3≤ML≤4.8) registrati dalla rete sismica gestita dall'INGV, avvenuti nell'area dell'Etna nel periodo compreso tra il 2002 e il 2021.</description>
    <description xml:lang="en" descriptionType="Methods">We collected basic data (locations and first polarities) from available datasets and published studies (Barberi et al., 2004; Alparone et al., 2012, 2013; Scarfì et al., 2013, 2016; Musumeci et al., 2014; De Guidi et al., 2015) and processed them by calculating the ray-tracing in the 3D velocity model of Firetto Carlino et al. (2021). By using FPFIT software (Reasenberg and Oppenheimer, 1985), we obtained 577 focal solutions with an average uncertainty on the orientation of the nodal planes of about 10°. These focal mechanisms can be considered representative of the kinematics characterizing Mt. Etna, since they are distributed in all the main seismogenically active areas of the region.</description>
    <description xml:lang="en" descriptionType="TechnicalInfo">The table shows the origin time, location and focal parameters of the analysed earthquakes. Specifically: No= identification number; Date (day-month-year); origin time (hour, minute and second); latitude north and longitude east; depth in km; magnitude; Strike, Dip and Rake of the first and second nodal plane; Strike and Dip of the P- and T-axes.</description>
