Only earthquakes with at least six observations were included. During this period, local magnitudes (ML) ranged from 0.0 to 4.6. Questo catalogo presenta la sismicità selezionata dal database dell’Istituto Nazionale di Geofisica e Vulcanologia (Alparone et al., 2023; Barberi et al., 2020; https://www.ingv.it/risorse-e-servizi/archivi-e-banche-dati), concentrandosi sugli eventi crostali superficiali (≤40 km di profondità) registrati da gennaio 2011 a dicembre 2023. Sono stati inclusi solo i terremoti con almeno sei osservazioni. In questo periodo, le magnitudo locali (ML) variano tra 0.0 e 4.6. The earthquake dataset was relocated using the tomoDDPS double-difference algorithm (Zhang et al., 2009) and a 3D velocity model derived by the integration of passive and active seismic data (the last acquired during the “TOMO-ETNA experiment”, FP7 “MED-SUV”, Barberi et al., 2018), to improve accuracy in hypocentre localization. The algorithm combines both absolute and differential arrival-time readings from pairs of closely spaced earthquakes, having the same velocity profile along the ray-path between source and a common receiver. Since the spatial and velocity paths are nearly identical, differences in arrival times can be attributed solely to the spatial offset between seismic events. Applying the 3D relocation method resulted in a more refined clustering of seismicity, reducing travel-time residuals by approximately 59%, with a mean residual of 0.03 seconds. The final hypocentral locations show horizontal and vertical uncertainties of approximately 0.12 ± 0.05 km and 0.17 ± 0.08, respectively. The table (PelAeolianEQ3D_2011-2023) shows the origin time and the hypocentre parameters of locations. Specifically: ID = identification number; Date (day-month-year); Origin Time (hour, minute, second and cent); Lat = latitude north in degrees; Long = longitude east in degrees; Depth in km; ML = local magnitude.
