Ideally this cyberinfrastructure provides amechanism for globally collaborative...

  3. Lava: Distribution Module Verification

    26 Jun 2014 | Contributor(s): Jacob Richardson, Laura J Connor

    A distribution module has been written in C, duplicating the algorithm accomplished in LavaPL. This document explains the ability for the C code to replicate the results of the Perl script and the misfit between the two scripts. Three maps illustrate the flow output of each model and the fit...

  9. 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...

  11. 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...

  18. 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...

  19. 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...

    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 ̄...
