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...

Large Scale Experiments on Volcanic Processes (EOS)
19 Jul 2011 | Contributor(s): Greg A Valentine
Some of the least understood and most hazardous geologic processes involve complex multiphase flows, particularly those related to explosive volcanic eruptions. These phenomena inherently involve a wide range of characteristic length and time scales, as well as processes that are coupled across...
