  1. PYFLOW_2.0. A new tool for estimating the impact parameters and the deposition rate and time of dilute PDCs based on field data

    22 Nov 2017 | Contributor(s): Marcus I Bursik

    PYFLOW_2.0 is a hazard tool for the calculation of the impact parameters of dilute pyroclastic density currents (DPDCs). DPDCs represent the dilute turbulent type of gravity flows that occur during explosive volcanic eruptions; their hazard is the result of their mobility and the capability...

  5. Confort 15 (Conflow improvement)

    22 Apr 2016 | Contributor(s): Marcus I Bursik

    We present an updated version of the Conflow model, an open-source numerical model for flow in eruptive conduits during steady-state pyroclastic eruptions (Mastin and Ghiorso, 2000). In the Confort 15 program, several updates were considered:The rheological parameters of the model are...

  6. 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

    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...

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

    15 Apr 2014

    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...
