Intrusive Seismic Swarms as Possible Precursors of Destructive Earthquakes on Mt. Etna’s Eastern Flank
Table 2
Intrusive seismic swarm parameters. The duration represents the time interval in which there is contemporaneity between seismicity and ground deformation ([30] and references therein; [50, 63]). The seismic moment was obtained by using (1) and (2) relationships. The 2018 values comprise an estimate of for the 1425 events with not included in the Bonaccorso and Giampiccolo [52] calculus. The last row reports data of the first phase of the October 1984 seismic swarm (16th at 14:00-18th at 12:00).
