Factors governing the flow lineation of a large-scale pyroclastic flow — An example in the ata pyroclastic flow deposit, Japan

Bulletin of Volcanology, 1983
Schmincke andSwanson (1967) explained laminar flowage structures as indicators for flow direction of pyroclastic flows that show a radial flow pattern away from the source. Several other authors have reported similar examples, but the influence of pre-flow topographic relief has not been analyzed.

Mobility of pyroclastic flows

Nature, 1977
THE mobility of pyroclastic flows has been described as spectacular1, in particular because of their ability to surmount obstacles in their path. It is relatively easy to estimate the minimum velocities required to climb a given height, if frictional losses are ignored.

Models for pyroclastic surges and pyroclastic flows

Journal of Volcanology and Geothermal Research, 1979
Pyroclastic surges are low-concentration turbulent flows that form in at least three ways: (1) eruption column collapse (ground surge, base surge), (2) elutriation from the top of a moving pyroclastic flow (ash cloud), and (3) directly from a crater without an accompanying vertical eruption column.∗ Ground surge deposits occur at the base and ash cloud

On pyroclastic flow emplacement

Journal of Geophysical Research: Solid Earth, 1993
In this note I investigate some theoretical characteristics of pyroclastic flow deposits, assuming that these flows are Bingham fluids, probably the simplest non‐Newtonian fluids. Pyroclastic flows are modeled as laminar debris flows moving on an inclined plane, and their physics is discussed within the classical framework of lubrication theory.

Pyroclastic flows modelling using cellular automata

Computers & Geosciences, 2006
Cellular automata (CA) and derived computational paradigms represent an alternative approach to differential equations to model and simulating complex fluid dynamical systems, whose evolution depends on the local interactions of their constituent parts.

Pyroclastic Flow Deposits

1984
Pyroclastic flows are volcanically produced hot, gaseous, particulate density currents. Their deposits offer unparalleled opportunities to estimate minimum volumes of near-surface magma chambers as well as vertical chemical, mineralogical, and thus temperature and pressure distributions within the magma columns immediately prior to eruption.
