  1. Supplementary material for Newhall and Pallister (2014) Using multiple data sets to populate probabilistic volcanic event trees

    27 Sep 2017 | Contributor(s): Chris Newhall, John S Pallister

    For probabilistic forecasting in volcanology, two widely used methods are the Cooke method (Aspinall and others) and BET-EF (Marzocchi and others).   The paper noted in the title, in Papale P (ed), Volcanic Hazards, Risks and Disasters. Academic Press, describes...

  2. La erupción del volcán Calbuco en 2015: Volcanología, sociedad y ecosistemas

    25 Apr 2017 | Contributor(s): Jorge E. Romero

    La erupción del 22-23 de abril de 2015 del Volcán Calbuco tuvo impactos en las actividades sociales y ecosistemas en el sur de Chile y en Argentina, debido a la espesa caída de piroclastos, corrientes calientes de gases y rocas, además de flujos de lodo...

  8. Multidisciplinary constraints of hydrothermal explosions based on the 2013 Gengissig lake events, Kverkfjöll volcano, Iceland

    29 Dec 2015 | Contributor(s): Cristian Montanaro

    Hydrothermal explosions frequently occur in geothermal areas showing various mechanisms and energies of explosivity. Their deposits, though generally hardly recognised or badly preserved, provide important insights to quantify the dynamics and energy of these poorly understood explosive events....

    29 Nov 2015 | Contributor(s): Sally H. Potter, Gill E. Jolly, Vince E. Neall, David M. Johnston, Bradley J. Scott

    The communication of scientific information to stakeholders is a critical component of an effective Volcano EarlyWarning System. Volcanic Alert Level (VAL) systems are used in many countries as a tool within early warning systemsto communicate complex volcanic information in a simple form, from...

  10. Los depósitos de caída de tefra: Una breve revisión sobre su cuantificación y análisis para la clasificación de erupciones volcánicas explosivas, con ejemplos Latinoamericanos

    15 Nov 2015 | Contributor(s): Jorge E. Romero

    La cuantificación de los depósitos volcánicos es una de las herramientas más utilizadas en la actualidad para clasificar la magnitud de la actividad volcánica y determinar los peligros volcánicos asociados. En el caso especial de las erupciones...

  11. VUELCO deliverable 7.5: Guidelines for the best practice of scientific management of volcanic unrest

    09 Sep 2015 | Contributor(s): dmitri rouwet

    Volcanic eruption forecasting and hazard assessment are multi-disciplinary processes with scientific and social implications. Our limited knowledge and the randomness of the processes behind a volcanic eruption yields the need of quantifying uncertainties on volcano dynamics. With deterministic...

  12. Towards the reconstruction of the shallow plumbing system of the Barombi Mbo Maar (Cameroon) Implications for diatreme growth processes of a polygenetic maar volcano

    30 Aug 2015 | Contributor(s): CHAKO TCHAMABE Boris, Takeshi Ohba, Gabor Kereszturi, Karoly Nemeth, Aka Festus Tongwa, Dieudone Youmen, Isabel Meza, Yasuo Miyabuchi, Seigo Ooki, Greg Zinkeng Tanyileke, Hell Joseph Victor

    Understanding the mechanisms involved in the formation of maars and their diatreme growth processes has been a subject of contention. While there is no direct evidence of the presence of diatremes beneath most of the young maars, their existence is inferred based on the amount and type of country...
