  • A Novel approach to reconstruct the plinian and co-ignimbrite phases of large eruptions - Campanian Ignimbrite 

    Marti, Alejandro; Folch, Arnau; Costa, Antonio; Engwell, Samantha (Barcelona Supercomputing Center, 2015-05-05)
    Conference report
    Open Access
    Reconstructing the volume and tephra dispersal from volcanic super-eruptions is necessary to assess the widespread impact of these massive events on climate, ecosystems and humans. Recent studies have demonstrated that ...
  • Beyond eruptive scenarios: assessing tephra fallout hazard from Neapolitan volcanoes 

    Sandri, Laura; Costa, Antonio; Selva, Jacopo; Tonini, Roberto; Macedonio, Giovanni; Folch, Arnau; Sulpizio, Roberto (Nature Publishing Group, 2016-04-12)
    Article
    Open Access
    Assessment of volcanic hazards is necessary for risk mitigation. Typically, hazard assessment is based on one or a few, subjectively chosen representative eruptive scenarios, which use a specific combination of eruptive ...
  • FPLUME-1.0: An integral volcanic plume model accounting for ash aggregation 

    Folch, Arnau; Costa, Antonio; Macedonio, Giovannin (EGU Journals, 2016-02-02)
    Article
    Open Access
    Eruption source parameters (ESP) characterizing volcanic eruption plumes are crucial inputs for atmospheric tephra dispersal models, used for hazard assessment and risk mitigation. We present FPLUME-1.0, a steady-state 1-D ...
  • Reconstructing the plinian and co-ignimbrite sources of large volcanic eruptions: A novel approach for the Campanian Ignimbrite 

    Marti, Alejandro; Folch, Arnau; Costa, Antonio; Engwell, Samantha (Nature Publishing Group, 2016-02-17)
    Article
    Open Access
    The 39 ka Campanian Ignimbrite (CI) super-eruption was the largest volcanic eruption of the past 200 ka in Europe. Tephra deposits indicate two distinct plume forming phases, Plinian and co-ignimbrite, characteristic of ...
  • Results of the eruptive column model inter-comparison study 

    Costa, Antonio; Suzuki, Yujiro J.; Cerminara, Matteo; Devenish, Ben J.; Ongaro, Tomaso E.; Herzog, Michael; van Eaton, Alexa R.; Denby, L. C.; Bursik, Marcus I.; Vitturi, M. de' Michieli; Engwell, Samantha L.; Neri, Augusto; Barsotti, Sara; Folch, Arnau; Macedonio, Giovanni V.; Girault, Frédéric; Carazzo, Guillaume; Tait, Steve R.; Kaminski, Édouard; Mastin, Larry G.; Woodhouse, Mark J.; Phillips, Jeremy C.; Hogg, Andrew J. C.; Degruyter, Wim; Bonadonna, Constanza (Elsevier, 2016-02-06)
    Article
    Open Access
    To improve our understanding of the physics of volcanic plumes and their interaction with the atmosphere, increasingly sophisticated numerical models of eruptive columns have been developed by a growing number of research ...
  • Uncertainties in volcanic plume modeling: A parametric study using FPLUME 

    Macedonio, Giovanni; Costa, Antonio; Folch, Arnau (Elsevier, 2016-10-15)
    Article
    Open Access
    We carry out a parametric study in order to identify and quantify the effects of uncertainties on pivotal parameters controlling the dynamics of volcanic plumes. The study builds upon numerical simulations using FPLUME, ...
