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 involve the ejection of dense mixtures of ash and gas from a
volcanic vent at high speed and pressure. This mixture is generated as liquid magma rises …

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 …

During the 1979 eruption of the Soufrière of St Vincent, West Indies, a 14 min period of
explosive activity occurred on April 22. The first three minutes of this activity were filmed …

The net effect of magma composition and water content on the behavior of explosive
volcanic eruptions was investigated by the use of thermofluid-dynamic models and …

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 …

Explosive volcanic eruptions frequently generate fall and flow deposits simultaneously,
which can be attributed to a marginally stable atmospheric column in transitional conditions …

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 …

Physical Processes in Volcanic Eruptions ADS Classic is now deprecated. It will be completely
retired in October 2019. This page will automatically redirect to the new ADS interface at that …

During explosive volcanic eruptions, fragmented silicic magma and volatiles exit the vent
with pressures typically in the range 10–100 atm and at the speed of sound of the mixture …
