  4. Bubble nucleation in H2O-CO2 bearing basaltic melts: results of high temperature decompression experiments

    26 Apr 2013 | Contributor(s): Nolwenn Le Gall, Michel Pichavant, Alain Burgisser

    AGU Meeting, San Francisco 2012Previous experiments have shown that mechanisms of basalt degassing are strongly contrasted when gas bubbles are present or when they are absent. Thus, experimental information on the kinetics of bubble nucleation in basaltic melts is needed, and high temperature...

  5. CO2-rich melts generated during basalt magma ascent and degassing

    26 Apr 2013 | Contributor(s): Michel Pichavant, Ida Di Carlo, Silvio Rotolo, Bruno Scaillet, Alain Burgisser, Nolwenn Le Gall, Caroline Martel

    AGU Meeting San Francisco 2012To test mechanisms of basaltic magma degassing, experimental decompressions of volatile-bearing (2.7-3.8 wt% H2O, 600-1300 ppm CO2) Stromboli melts have been performed from 250-200 to 50-25 MPa at 1180-1140°C. Ascent rates were varied from 0.25 to ~ 1.5 m/s. Both the...

  6. Volcanic Threat in Central America

    14 Apr 2013 | Contributor(s): Jose L. Palma

    (Presented at AGU Fall Meeting in 2008)This presentation shows an assessment of the volcanic threat posed by the 23 most active and best documented volcanoes in Central America. It also includes a preliminary evaluation for all volcanoes in Guatemala. The results are compared to the threat posed...

    Global volcanic unrest in the 21st Century: An analysis of the first decadeVolcanic unrest is perhaps best defined as the deviation from the background or baseline behaviour of a volcano towards a level of activity, which is cause for concern in the short-term because it might be a prelude to an...

  11. The sensitivity of conduit flow models to basic input parameters: there is no need for magma trolls! Geophysical Research Abstracts Vol.14, EGU2012-8467, 2012.

  12. Phillipson and Gottsmann EGU2012 Vol. 14, EGU2012-3695, 2012

    20 Mar 2013 | Contributor(s): Jo Gottsmann

    Volcanic unrest is the deviation from the background or baseline behaviour of a volcano towards a level of activity, which is cause for concern in the short term because it might be a prelude to an eruption. When volcanic unrest is preceded by lengthy periods of quiescence it is particularly...

  13. J. Gottsmann EGU 2012 Abstract Vol. 14, EGU2012-2353, 2012

    20 Mar 2013 | Publications | Contributor(s): Jo Gottsmann

    In this presentation I explore magma chamber stress conditions prior to a large-magnitude andesitic eruption and associated pre-eruptive ground deformation and gravity field perturbations. The analyis is informed by constraints from multi-disciplinary investigations of the data-rich and ongoing...

  16. An assessment of hydrothermal alteration in the Santiaguito lava dome complex, Guatemala: implications for dome collapse hazards

    28 Feb 2013 | Publications | Contributor(s): Jessica L. Ball, Eliza S Calder, Marc Bernstein

    A combination of field mapping, geochemistry, and remote sensing methods has been employed to determine the extent of hydrothermal alteration and assess the potential for failure at the Santiaguito lava dome complex, Guatemala. The 90-year-old complex of four lava domes has only experienced...
