Ensemble-Based Data Assimilation of Volcanic Ash Clouds from Satellite Observations: Application to the 24 December 2018 Mt. Etna Explosive Eruption

Pardini F, S. Corradini, A. Costa, Tomaso Esposti Ongaro, L. Merucci, A. Neri, D. Stelitano and Mattia de’ Michieli Vitturi (2020).Atmosphere, 11/4, 359; https://doi.org/10.3390/atmos11040359. Abstract Accurate tracking and forecasting of ash dispersal in the atmosphere and quantification of its uncertainty are of fundamental importance for volcanic risk mitigation. Numerical models and satellite…

A framework for validation and benchmarking of pyroclastic current models

Esposti Ongaro T., M. Cerminara, S. J. Charbonnier, G. Lube & G. A. Valentine (2020). A framework for validation and benchmarking of pyroclastic current models.Bulletin of Volcanology, 82/51, https://doi.org/10.1007/s00445-020-01388-2. Abstract Numerical models of pyroclastic currents are widely used for fundamental research and for hazard and risk modeling that supports decision-making and crisis management. Because of their…

Estimating eruptive parameters and related uncertainties for pyroclastic density currents deposits: worked examples from Somma-Vesuvius (Italy)

Cioni R., A. Tadini, L. Gurioli, A. Bertagnini, M. Mulas, A. Bevilacqua & A. Neri (2020).Bulletin of Volcanology, 82/65, https://doi.org/10.1007/s00445-020-01402-7. Abstract The quantification of the maximum runout, invaded area, volume, and total grain-size distribution (TGSD) of pyroclastic density currents (PDC) is a critically important task because such parameters represent the needed necessary input quantities for physical modeling…

Multiphase flow behaviour and hazard prediction of pyroclastic density currents

Lube G., E.C. P. Breard, T. Esposti-Ongaro, J. Dufek and B. Brand (2020).Nature Reviews – Earth & Environment, 1, 348–365, https://doi.org/10.1038/s43017-020-0064-8. Abstract Pyroclastic density currents (PDCs) are dangerous multiphase flows originating from volcanic eruptions. PDCs cause more than a third of volcanic fatalities globally and, therefore, development of robust PDC…
