Reconciling pyroclastic flow and surge: the multiphase physics of pyroclastic density currents [PDF]

Earth and Planetary Science Letters, 2002
Two end-member types of pyroclastic density current are commonly recognized: pyroclastic surges are dilute currents in which particles are carried in turbulent suspension and pyroclastic flows are highly concentrated flows. We provide scaling relations that unify these end-members and derive a segregation mechanism into basal concentrated flow and ...

A fast, calibrated model for pyroclastic density currents kinematics and hazard [PDF]

Journal of Volcanology and Geothermal Research, 2016
Abstract Multiphase flow models represent valuable tools for the study of the complex, non-equilibrium dynamics of pyroclastic density currents. Particle sedimentation, flow stratification and rheological changes, depending on the flow regime, interaction with topographic obstacles, turbulent air entrainment, buoyancy reversal, and other complex ...

Pyroclastic density current volume estimation after the 2010 Merapi volcano eruption using X-band SAR

Journal of Volcanology and Geothermal Research, 2013
Pyroclastic density current deposits remobilized by water during periods of heavy rainfall trigger lahars (volcanic mudflows) that affect inhabited areas at considerable distance from volcanoes, even years after an eruption.Here we present an ...
