Plinian air-fall deposits and ignimbrites are the principal products of explosive eruptions of
high viscosity magma. In this paper, the flow of gas/pyroclast dispersions and high viscosity …

The mechanisms controlling the transport of pyroclasts in a plinian-type eruption column are
discussed. An estimate is made of the density of the magmatic gas in the vent, and initial …

A simple model is developed to relate the maximum down-wind and cross-wind ranges of
pyroclasts forming a plinian airfall deposit to the dynamic processes in the eruption cloud …

Peak intensities (magma discharge rate) of 45 Pleistocene and Holocene plinian eruptions
have been inferred from lithic dispersal patterns by using a theoretical model of pyroclast …

A theory of a volcanic eruption as a steady magma flow from a magma chamber to the
surface is described. Magma is considered as a two-component two-phase medium and …

A physical model is developed to determine factors which influence the dynamics of non-
explosive lava eruptions. In the model, magma rises in a laminar regime from an …

The role of anhydrous magma composition, water content, and crystal content on the
dynamics of explosive eruptions is investigated by modeling the ascent of magma along …

The scope of this chapter is limited to the dynamics of lava and gas rising in a volcanic
conduit. No mention will be made of the behaviour of eruption columns in the atmosphere …

This paper describes a series of laboratory experiments in which buoyant mixtures of
methanol and ethylene glycol (MEG) are injected as a downward propagating jet into a tank …

Explosive volcanic eruptions are triggered when magma is sufficiently overpressured to
open up a fracture to the surface and the eruption continues until this overpressure is …
