“…March-August 1983 upper south flank (Gresta & Patan? 1983b;Patan?, Gresta & Imposa 1984), November 1978 at the Southeast Crater as well as from fractures in the North of Valle del Bove in 1979 (Cosentino & Lombardo 1984). These studies have documented such features as the development of shallow seismicity of relatively small magnitude preceding, by up to a few days, the opening of flank fissures, and/or proposed an analysis showing that during a period of continued seismic activity a change in the b-value of the number of earthquakes versus magnitude statistics related to eruptions.…”

S U M M A R YA local array was deployed on Mt Etna to follow precisely the seismic activity occurring at the end of the eruption of the Southeast Crater in October 1984. Swarm activity at sea level beneath the summit was followed by isolated earthquakes a few kilometres deeper and more distant and eventually by destructive earthquakes on the lower slopes.There was no continuous migration between these domains of eruptive and seismic activity but the time relation is striking.A revised use of the exceptional record over four centuries of eruptions and destructive earthquakes in the Mt Etna region documents the statistical significance of this type of occurrence of major earthquakes in relation to the end of eruptions, in addition to the previously emphasized significance of the relation between earthquakes and the onset of lateral eruptions.

The event chronology of the 1983 Etna eruption is summarized, and the development of a compound lava field at different time intervals during the eruption is described as observed from aerial photographs.The morphological evolution of the lava fronts has been compared with effusion rate and principal modifications occurring in the main channel, and it has been inferred that the development of the lava flow units is related to the formation of lava tunnels and particularly of lava channels. The total volume of lava emitted has been estimated to be 100+20×106 m 3 according to two different methods. Finally, the comparison with previous historical eruptive activity shows a good correlation to other quiet eruptions.
