    Deep-sea eruptions boosted by induced fuel–coolant explosions 
    Dürig, Tobias; White, J. D. L.; Murch, A. P.; Zimanowski, B.; Büttner, R.; Mele, D.; Dellino, P.; Carey, R. J.; Schmidt, L. S.; Spitznagel, N. (Springer Science and Business Media LLC, 2020-06-29)
    The majority of Earth’s volcanic eruptions occur beneath the sea, but the limited number of direct observations and samples limits our understanding of these unseen events. Subaerial eruptions lend some insight, but direct extrapolation from the subaerial ...

    Deep-sea fragmentation style of Havre revealed by dendrogrammatic analyses of particle morphometry 
    Dürig, Tobias; White, J. D. L.; Zimanowski, B.; Büttner, R.; Murch, A.; Carey, R. J. (Springer Science and Business Media LLC, 2020-09-30)
    In 2012, the eruption of deep-sea volcano Havre produced an abundance of fine ash at a depth of ~ 1000 m below sea level. In this study the 2D shapes of Havre ash grains retrieved from the seafloor were compared quantitatively with those of particles ...

    The effect of wind and plume height reconstruction methods on the accuracy of simple plume models — a second look at the 2010 Eyjafjallajökull eruption 
    Dürig, Tobias; Guðmundsson, Magnús T.; Ágústsdóttir, Thorbjörg; Högnadóttir, Thórdís; Schmidt, Louise (Springer, 2022-02-28)
    Real-time monitoring of volcanic ash plumes with the aim to estimate the mass eruption rate is crucial for predicting atmospheric ash concentration. Mass eruption rates are usually assessed by 0D and 1D plume models, which are fast and require only a ...

    Lava field evolution and emplacement dynamics of the 2014–2015 basaltic fissure eruption at Holuhraun, Iceland 
    Pedersen, Gro; Höskuldsson, Ármann; Dürig, Tobias; Thordarson, Thorvaldur; Jonsdottir, Ingibjorg; Riishus, M. S.; Óskarsson, B.V.; Dumont, Stéphanie; Magnússon, Eyjólfur; Gudmundsson, Magnus Tumi; Sigmundsson, Freysteinn; Drouin, V.J.P.B.; Gallagher, C.; Askew, R.; Gudnason, J.; Moreland, William; Nikkola, P.; Reynolds, Hannah Iona; Schmith, Johanne (Elsevier BV, 2017-06)
    The 6-month long eruption at Holuhraun (August 2014–February 2015) in the Bárðarbunga-Veiðivötn volcanic system was the largest effusive eruption in Iceland since the 1783–1784 CE Laki eruption. The lava flow field covered ~84 km2 and has an estimated ...

    A review of statistical tools for morphometric analysis of juvenile pyroclasts 
    Dürig, Tobias; Ross, Pierre-Simon; Dellino, Pierfrancesco; White, James D. L.; Mele, Daniela; Comida, Pier Paolo (Springer Nature, 2021-10-30)
    Morphometric analyses are based on multiparametric datasets that describe quantitatively the shapes of objects. The stochastic nature of fracture-formation processes that break up magma during explosive eruptions yields mixtures of particles that have ...

    Seismic Amplitude Ratio Analysis of the 2014-2015 Bárðarbunga-Holuhraun Dike Propagation and Eruption 
    Caudron, Corentin; White, Robert S.; Green, Robert G.; Woods, Jennifer; Agustsdottir, Thorbjorg; Donaldson, Clare; Greenfield, Tim; Rivalta, Eleonora; Brandsdóttir, Bryndís (American Geophysical Union (AGU), 2018-01)
    Magma is transported in brittle rock through dikes and sills. This movement may be accompanied by the release of seismic energy that can be tracked from the Earth's surface. Locating dikes and deciphering their dynamics is therefore of prime importance ...

    Standardized analysis of juvenile pyroclasts in comparative studies of primary magma fragmentation: 2. Choice of size fraction and method optimization for particle cross-sections 
    Comida, Pier Paolo; Ross, Pierre-Simon; Dürig, Tobias; White, James D. L.; Lefebvre, Nathalie (Springer Nature, 2021-12-27)
    The morphological and textural features of juvenile pyroclasts record crucial details on magma conditions at the time of fragmentation. Their study is therefore essential to better understand the dynamics of explosive eruptions. Unfortunately, the ...
