UNDERSTANDING ERUPTIVE DYNAMICS, PLUME DISPERSAL AND PARTICLE TRANSPORT FOR RISK ASSESSMENT IN PAROXYSMAL MAFIC ERUPTIONS
… This thesis presents a study of several lava-fountain episodes at Etna that occurred between 2021 and 2024. Its aim is to improve our understanding of eruptive dynamics and better characterize key eruptive parameters used in monitoring operations for modelling tephra dispersal (Eruptive …

Experimental and Computational Approaches to Enhance the Gravimetric Monitoring of Volcanic Areas
… two different stations during the 10 April 2011 lava fountain, one of the strongest paroxysmal episode in 2011 eruptive events, were analyzed. Finally, to separate the signal from the gravimeter into gravity field contribute due to the subsurface mass or density variations and the inertial …

Multi-parametric study of the 2020-2022 paroxysmal activity at mt. Etna: the role of fluids in the trigger mechanisms, durations and energy of the eruptive phenomena [Studio multi-parametrico dell’attività parossistica del 2020-21 al Mt. Etna: ruolo dei fluidi sui meccanismi di innesco, durata ed energia dei fenomeni eruttivi]
… ampiezze di deflazione associate alle fontane di lava e ad altri parametri chiave come le velocità di inflazione e deflazione e le ampiezze del tremore vulcanico. Il Periodo I, che si sovrappone alla prima fase, è stato caratterizzato da valori più elevati di questi parametri, indicando il …
