Cover Story: A statistical analysis of the effusion rate of recent flank eruptions at Mt Etna was performed, finding that most peaks occur at the beginning of eruptions, between 0.5% and 29% of the total duration, followed by a progressive decrease. Three generalized curves were derived through the calculation of the 25th, 50th, and 75th percentiles linked to the distribution of peaks and slope variations. Lava flow simulations were run by using each characteristic curve to quantify the differences in run-out distance, proving that an early incidence of the effusion rate peak can induce variations up to 40%. Our tests highlights how effusion rate strongly influences the emplacement of lava flow fields, with significant repercussion both on long- and short-term hazard assessment associated with effusive eruptions.
