  1. BENCHMARKING LAVA FLOWS -BM2- INCLINED ISOTHERMAL VISCOUS SPREADING

    26 Jun 2014 | Contributor(s): Fanny Garel, Benoit BJR Cordonnier, Einat Lev

    The lava flow team has agreed on benchmarking series.Among which, benchmark #2 represents a benchmark test for an isothermal viscous flow on an inclined plane.This benchmark, combined with BM#1, is useful to test how well fast-computing models handle a simple viscous flow geometry.Flow...

  5. PyFlow

    07 May 2014 | Contributor(s): Fabio Dioguardi, Pierfrancesco Dellino, Daniela Mele

    PYFLOW is a multi-block code for the calculation of the flow field variables of dilute pyroclasticdensity currents (hereafter DPDCs) starting from the deposits characteristics. The code, written inFortran 90, solves an improved version of the model of Dellino et al. (2008): it calculates...

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

    15 Apr 2014 | 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...

  9. The Volcanic Hazards Simulation

    31 Mar 2014 | Contributor(s): Jacqueline Dohaney, Erik Brogt, Ben Kennedy, Thomas Wilson, Rebecca Fitzgerald

    The Volcanic Hazards Simulation is a half-day capstone activity targeted at upper year geology and emergency management students. It is a complex role-play, where students and instructors play authentic roles and respond to a volcanic crisis scenario. The data for the simulation is delivered via...

  14. Geophysical signatures of magma chamber replenishment

    14 Mar 2014 | Contributor(s): Antonella Longo, Chiara Paola Montagna, Gilberto Saccorotti, Paolo Papale

    Many volcanic eruptions are shortly preceded by new magma injection into a pre-existing, shallow (< 10 km) magma chamber, causing convection and mixing between the incoming and resident magmas. These processes may trigger dyke propagation and further magma rise, inducing long-term (days to...

  15. Simplifying assumptions in volcano modeling: are we missing something crucial?

    14 Mar 2014 | Contributor(s): Chiara Paola Montagna, Antonella Longo, Paolo Papale, Gilberto Saccorotti

    Volcanoes are extremely complex natural systems, in which the interplay of different forces and physical processes determines a variety of behaviors that can be hard to interpret. The deep magmatic systems cannot be directly observed, and we must rely on indirect information. The latter typically...

  16. Magma flow between summit and Pu`u `O`o at Kilauea volcano, Hawai`i

    14 Mar 2014 | Contributor(s): Chiara Paola Montagna, Helge Gonnermann

    Volcanic eruptions are often accompanied by spatiotemporal migration ofground deformation, a consequence of pressure changes within magma reser-voirs and pathways. We model the propagation of pressure variations byeruptive magma withdrawal during the early episodes of the ongoing Pu‘u ̄...

  17. Complex magmatic systems and geophysical signal analysis: what can we understand from inversions?

    14 Mar 2014 | Contributor(s): Chiara Paola Montagna, G. Saccorotti, P. Papale, A. Longo

    Many volcanic eruptions are shortly preceded by new magma injection into a pre-existing, shallow (< 10 km) magma chamber, causing convection and mixing between the incoming and resident magmas. These processes may trigger dyke propagation and further magma rise, inducing long-term (days to...
