14 GNGTS 2019 S essione 1.1 Conclusions. This research is focused on the study of three earthquakes that occurred in the lower southern sector of Mt. Etna. The integration of INGV-OE seismic data with those from the station managed by the University of Catania (SGR) has allowed improving the hypocenter earthquake parameters and consequently the conjunction of seismic sources with the structural lineaments of the survey area. The evidence of activation of southern flank of volcano could be related to extensometers data, which in the same period, recorded some millimetric variations. This multidisciplinary study will allow to better understand the complex geodynamics of the lower southern slope of the volcano and to link this with the eruptive activity of Mt. Etna volcano. Acknowledgments. A special thanks to the Municipality of San Gregorio di Catania (CT) which enabled installing the seismic station and provided considerable logistic support. This work was funded by the Dipartimento di Scienze Biologiche, Geologiche e Ambientali, Università degli Studi di Catania, in the frame of “Piano Nazionale della Ricerca 2019”.
