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...

VHAST

04 Apr 2013 | Contributor(s): Gabriel Andrés Bernal

VHAST (Volcanic Hazard Analysis and Simulation Tool)is a probabilistic volcanic hazard assessment software. It has been developed in Visual Basic .NET and runs on Windows XP or later. VHAST supports hazard analysis of lava flows, pyroclastic flows and ash fall, using simplified models.The...

Large Scale Experiments on Volcanic Processes (EOS)

19 Jul 2011 | Publications | 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...
