A review of the volcano-magnetic effects observed between 1981 and 1995 onMount Etna (Italy)

Detection of local magnetic field perturbations has often been proposed for monitoring the modifications within the volcanic edifice of the stress fie ld or of the thermodynamic state and providing a tool for prediction of eru ptions. In order to evaluate the suitability of magnetic monitoring on Mt. Etna, we analysed two historic series of magnetic data recorded there: i) d uring the 1981 eruption and ii) immediately after 1989 eruption. Moreover, we examined time series associated with the intense explosive activity of E tna in 1995 summer provided by the present permanent magnetic network which was set up between 1994 and 1995.
