Pyroclastic density currents (PDCs) represent some of the most formidable and complex volcanic phenomena, characterised by a turbulent mixture of solid particles and gases that surge down slopes at ...

Figure 1: Synthesizing pyroclastic density currents in large-scale experiments. Figure 3: Experimental deposit and timescale of deposition. The discovery of mesoscale clusters in PDCs has major ...

One of the leading killers during explosive volcanic eruptions is a family of superheated gas, ash, and debris known as pyroclastic density currents. These tumbling, turbulent paroxysms rush downslope ...
