Description:
We have processed thirty Global Positioning System
(GPS) campaigns carried out at Etna from 1994 to early
2001 between the last two main flank eruptions of the Mt.
Etna (Sicily, Italy). This rest period allowed us to investigate
the deep magma plumbing system of the Mt. Etna. The
temporal dynamics of twenty-three points observed three
times or more were analyzed. All the time series show a
first-order linear trend during the five years period. It
suggests that the volcano was continuously deformed by the
action of a deep source while a discrete activity of the
volcano was observed at the summit. We have interpreted
the residual deformation field as the result of an major
eastward motion of the eastern flank of the volcano.
