The Total Volatile (TV) flux from Mount Etna volcano has been characterised for the first time, by summing the simultaneously‐evaluated fluxes of the three main volcanogenic volatiles: H 2 O, CO 2 and SO 2 . SO 2 flux was determined by routine DOAS traverse measurements, while H 2 O and CO 2 were evaluated by scaling MultiGAS‐sensed H 2 O/SO 2 and CO 2 /SO 2 plume ratios to the UV‐sensed SO 2 flux. The time‐averaged TV flux from Etna is evaluated at ∼21,000 t·day −1 , with a large fraction accounted for by H 2 O (∼13,000 t·day −1 ). H 2 O dominates (≥70%) the volatile budget during syn‐eruptive degassing, while CO 2 and H 2 O contribute equally to the TV flux during passive degassing. The CO 2 flux was observed to be particularly high prior to the 2006 eruption, suggesting that this parameter is a good candidate for eruption prediction at basaltic volcanoes.
