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

    28 Feb 2013 | 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...

  5. ASHEE

    14 Aug 2015 | Contributor(s): Matteo Cerminara, Tomaso Esposti Ongaro

    A fluid-dynamic model is developed to numerically simulate the non-equilibrium dynamics of polydisperse gas-particle mixtures forming volcanic plumes. Starting from the three-dimensional N-phase Eulerian transport equations for a mixture of gases and solid particles, we adopt an asymptotic...

  6. bent: A model of plumes in crossflow

    11 Nov 2010 | Contributor(s): Marcus I Bursik

    Bent is an integral trajectory model for calculation of plume parameters in the presence of a crossflow (wind). It has been validated against data for eruptions from Kliuchevskoi and Avachinskiy volcanoes, Russia.
