Long-runout pyroclastic density currents: Analysis and implications

open access: yesGeology, 2022
Abstract Pyroclastic density currents are hazardous, ground-hugging, hot mixtures of gas and solid particles produced by volcanoes. Currents generated by the largest explosive eruptions have traveled distances on the order of 100 km, and their devastating impact has repeatedly marked Earth's geologic history.

Energy facies. A global view of pyroclastic currents from vent to deposit

open access: yes, 2022
Pyroclastic currents are described as gravity currents, and the classic conceptual model gives a first-order importance to the density of such currents.

Patterns of deposition from experimental turbidity currents with reversing buoyancy [PDF]

open access: yes, 2010
Turbidity currents are turbulent, sediment-laden gravity currents which can be generated in relatively shallow shelf settings and travel downslope before spreading out across deep-water abyssal plains.

Experimental study of dense pyroclastic density currents using sustained, gas-fluidized granular flows [PDF]

open access: yes, 2014
International audienceWe present the results of laboratory experiments on the behaviour of sustained, dense granular flows in a horizontal flume, in which high-gas pore pressure was maintained throughout the flow duration by continuous injection of gas ...

Pyroclastic density currents

open access: yes, 2013
This chapter summarizes the principal experimental and theoretical approaches used to investigate the physics of pyroclastic density currents (PDCs), which are gravity driven hot gas–particle mixtures commonly generated during explosive volcanic eruptions.
