Short summary

In 1984, several seismic events, caused one fatality, 12 injuries and produced serious damage in eastern flank of Mt. Etna. We inverted ground deformation (EDM) data finding that in 1980–84 period, the Fiandaca Fault was affected by a strike slip and normal dip slip of ca. 20.4 and 12.7 cm. This is consistent with field observations (ground ruptures) but it it is notably large compared to displacements estimated by seismicity, then suggesting that most of most of the slip was aseismic.
