  8. MeMoVolc workshop on the "Dynamics of volcanic explosive eruptions", Consensual Document

    15 Jul 2014 | Publications | Contributor(s): Costanza Bonadonna, Raffaello Cioni, Antonio Costa, Tim Druitt, Jeremy Phillips, Laura Pioli

    This workshop served to assess the main advantages and shortcomings of existing eruption classification schemes and to identify open questions and research priorities that could help improve our understanding of volcanic explosive eruptions. We identified the main parameters and processes...

  9. Pyroclastic density currents and local topography as seen with the conveyer model

    15 Apr 2014 | Publications | Contributor(s): Domenico M. Doronzo

    Pyroclastic density currents (PDCs) are multiphase flows generated during explosive volcanic eruptions, and they move down the volcano, and over the surrounding topography. The flow-topography interaction can play a fundamental role in the sedimentary processes, and in the resulting deposit...

  10. Towards a probabilistic scheme: How can we recognize and track non-magmatic unrest and related hazards?

    18 Feb 2014 | Publications | Contributor(s): dmitri rouwet, Laura Sandri, Warner Marzocchi, Jo Gottsmann

    Eruption forecasting is a major goal in volcanology. The intrinsic complexity and non-linearity of volcanic systems has recently led to an intertwining of deterministic to probabilistic eruption forecasting methods. However, many volcanoes often pass states of non-eruptive and non-magmatic unrest...

  12. Estimating Volcanic Risk in the Lesser Antilles

    26 Sep 2013 | Publications | Contributor(s): Michal Camejo, Richard E.A. Robertson

    The potential catastrophic effects of future volcanic eruptions in the Lesser Antilles can be decreased by the utilisation of effective risk quantification measures and their subsequent incorporation into disaster risk reduction strategies. A volcanic risk study conducted by the Norwegian...

  13. Spherulites and thundereggs from pitchstones of the Deccan Traps: geology, petrochemistry, and emplacement environments

    18 Sep 2013 | Publications | Contributor(s): Pooja Vinod Kshirsagar

    Spherulites and thundereggs are rounded, typically spherical, polycrystalline objects found in glassy silicic rocks. Spherulites are dominantly made up of radiating microscopic fibers of alkali feldspar and a silica mineral (commonly quartz). They form due to heterogeneous nucleation in highly...

  14. Mafic alkalic magmatism in central Kachchh, India- a monogenetic volcanic field in the northwestern Deccan Traps

    18 Sep 2013 | Publications | Contributor(s): Pooja Vinod Kshirsagar, Badre Alam shaikh, Hetu Sheth

    Magmatism in Kachchh, in the northwestern Deccan continental flood basalt province, is represented not only by typical tholeiitic flows and dikes, but also plug-like bodies, in Mesozoic sandstone, of alkali basalt, basanite, melanephelinite and nephelinite, containing mantle nodules. They form...

  15. Global volcanic unrest in the 21st century: An analysis of the first decade

    16 Sep 2013 | Publications | Contributor(s): Jo Gottsmann, Rosa Sobradelo

    We define volcanic unrest as the deviation from the background or baseline behaviour of a volcano towards a behaviour which is a cause for concern in the short-term because it might prelude an eruption. When unrest is preceded by periods of quiescence over centuries or millennia it is...

  17. Correlation of Magma Evolution and Geophysical Monitoring during the 2011^2012 El Hierro (Canary Islands) Submarine Eruption

    04 Sep 2013 | Publications | Contributor(s): Joan Marti, Antonio Castro, Carmen Rodriguez, Fidel Costa, Sandra Carrasquilla, Rocio Pedreira, Xavier Bolos

    The application of petrography, mineral chemistry, geochemistry, and xperimental petrology, including mineral^melt thermodynamic and diffusion modelling, on quenched basanitic magma samples from the recent (2011^2012) submarine eruption of El Hierro (Canary Islands) has permitted the...

  18. Electrical resistivity tomography revealing the internal structure of monogenetic volcanoes

    04 Sep 2013 | Publications | Contributor(s): Stephanie Barde-Cabusson, Xavier Bolos, Dario Pedrazzi, Raul Lovera, Guillem Serra, Joan Marti, Albert Casas

    Eruptive activity of individual monogenetic volcanoes usually lasts a few days or weeks. However, their short lifetime does not always mean that their dynamics andstructure are simple. Monogenetic cones construction is rarely witnessed from the beginning to the end, and conditions for observing...
