This work describes the main characteristics of the seismicity due to the volcano-tectonic events recorded at Mount Etna during 2020. The data are recorded by the seismic stations of the Permanent Seismic Network operated by National Institute of Geophysics and Volcanology – Etna Observatory (INGV - OE). In this year, about 100 seismic stations constitute the network. The seismic data are first transmitted in real time to the Unified Data Acquisition Centre (CUAD) and then continuously transferred and recorded in the Control Room of INGV – OE. The Analyst Working Group of the Etna Observatory (GLAOE) reviews and reprocesses the seismic data the day after they are acquired, observing standard protocols which are adopted for the compilation of the catalogues and the databases relative to...
