S. Leonardi et al., Searching for a significant correlation between volcanic tremor amplitude and SO2 emissions at Mount Etna volcano, Sicily, GEOPHYS J I, 141(3), 2000, pp. 832-834
A strong correlation between the amplitude of volcanic tremor and the flux
of SO2 has been found at Mount Etna volcano, Sicily, corresponding to enhan
ced volcanic activity in the period 1987-1995. We therefore suggest that tr
emors and SO2 emissions have a common physical origin linked to the magma d
ynamics of the volcano.
