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): Fabio Dioguardi, Daniela Mele, Pierfrancesco Dellino

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...

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...

Underwater volcano disaster - an Oxford Sparks Animation

19 Mar 2014 | Contributor(s): David Pyle

A short (2 minute) animation of a subduction zone and volcano, introducing the processes involved in subduction, melting and volcanism.This animation can be used as a stand alone item, or in a classroom. We have developed some class activities around an exercise in volcano monitoring at an...
