Description

The new hazard map for lava flows inundation at the summit of Mt. Etna volcano obtained by using a probabilistic approach that considers both the long-lasting sub-terminal eruptions, and the short-lasting paroxysmal events from the summit craters: North East Crater (NEC), South East Crater (SEC), Voragine (VOR) and Bocca Nuova (BN).

Methods (English)

The methodology includes different stages: (i) the definition of the classes of the expected eruptions, effusion rate curves and their occurrence probability; (ii) assessment of the spatiotemporal probability of future vent opening, by assuming two different probability distributions; (iii) running of lava flows emplacements considering a large number of eruptive scenarios with the GPUFLOW model; (iv) computation of the long-term probability for each point of the area interested by simulated lava flows; (v) validation of the best approach.
