Volcanic eruption plumes on Io

Nature, 1979
Preliminary analyses of the eight volcanic eruption plumes detected on Io by Voyager 1 are presented. Plumes were observed on the bright and dark limbs of the satellite corresponding to half of the surface and range from 10,000 to 75 km in width and 280 to 70 km in height.

Particle recycling in volcanic plumes

Bulletin of Volcanology, 2001
We have developed a new theoretical model of an eruption column that accounts for the re-entrainment of particles as they fall out of the laterally spreading umbrella cloud. The model illustrates how the mass flux of particles in the plume may increase with height in the plume, by a factor as large as 2.5 because of this recycling.

BrO formation in volcanic plumes

Geochimica et Cosmochimica Acta, 2006
Volcanoes have only recently been recognized as a potentially major source of reactive bromine species to the atmosphere, following from the detection of bromine monoxide (BrO) in the plume emitted by Soufriere Hills Volcano, Montserrat. However, BrO is not expected to be emitted in significant quantity from magma, presenting a puzzle regarding its ...

Hearing a volcanic plume

Science, 2017
Volcanology![Figure][1] CREDIT: ASSOCIATED PRESS, COLT SNAPP Monitoring remote eruptions—such as that of Pavlof Volcano, Alaska, in 2016—is challenging. Fee et al. found that the height of the ash plume during the Pavlof eruption could be inferred from sound waves detected by ...

Dynamics of volcanic plumes on Io

Nature, 1979
Ballistic and aerodynamic models are proposed to explain the dynamics of the volcanic plumes on Io. A ballistic model, which assumes that eruptive gas and solid-particle flows become completely and permanently decoupled over a small distance as compared with the maximum particle height, is shown to be unable to account for the observed shape of Plume 3.

Volcanic plume imagery from Meteosat‐9

Weather, 2011
Figure 1. The height of the top of the volcanic ash layer from the Eyjafjallajokull eruption at 0800 UTC on 13 May 2010, almost a month after the initial eruption. This is derived from Meteosat-9 infrared imagery using a 1DVar retrieval. (© EUMETSAT/MetOffice.) Figure 2.
