Abstract

A strong correlation between the amplitude of volcanic tremor and the flux of SO2 has been found at Mount Etna volcano, Sicily, corresponding to enhanced volcanic activity in the period 1987–1995. We therefore suggest that tremors and SO2 emissions have a common physical origin linked to the magma dynamics of the volcano.
