Rheology of nanocrystal-bearing andesite magma and its roles in explosive volcanism
Communications Earth & Environment, 2022 Nanolite crystallisation increases bulk viscosity in mafic to intermediate magmas but other mechanisms are required to promote explosive eruptions, according to an experimental study using natural samples.

Ice core evidence for a second volcanic eruption around 1809 in the Northern Hemisphere [PDF]
, 2006 A volcanic signal observed in ice cores from both polar regions six years prior to Tambora is attributed to an unknown tropical eruption in 1809. Recovery of dacitic tephra from the 1809 horizon in a Yukon ice core (Eclipse) that is chemically distinct ...

Explosive volcanism on Venus: Transient volcanic explosions as a mechanism for localized pyroclast dispersal [PDF]
Journal of Geophysical Research: Planets, 1995 It is proposed that transient volcanic explosions of the vulcanian type may provide a mechanism for the generation and dispersal of pyroclastic material on Venus. The influence of the Venusian high atmospheric pressure environment implies that continuous discharge plinian eruptive activity is relatively uncommon: the tendency for suppression of ...

Explosive volcanic eruptions-VII. The ranges of pyroclasts ejected in transient volcanic explosions [PDF]
Geophysical Journal International, 1993 An earlier treatment of the motions of pyroclasts produced in discrete volcanic explosions assumed that clasts were ejected into a stationary atmosphere. We argue here that the air in the vicinity of an explosion site will itself be moving radially away from the source with a speed comparable to that of the clasts, especially at early times after the ...

Marine tephrochronology: a personal perspective [PDF]
, 2014 This special volume on marine tephrochronology is remarkable, and timely, because it marks a concerted step towards what might be informally termed ‘phase 3’ of a revolution in Quaternary geosciences that began around 40 years ago.

Terrestrial, Atmospheric and Oceanic Sciences, 2009 The giant piston core MD01-2387 taken from the eastern Celebes Sea basin provides a marine tephrostratigraphy with higher solution for inferring explosive volcanism in the area surrounding the basin for the past 350 kyr.

External ballistic of volcanic explosions [PDF]
Bulletin Volcanologique, 1983 In order to determine the kinetic energy of an explosion it is necessary to know the initial velocities of ejected fragments. Calculations of initial velocities made earlier with few exceptions did not take into account the resistance of the air and therefore, greatly underestimated the initial velocities, and consequently the energy of the explosions.

SO2 emissions from basaltic eruptions, and the excess sulfur issue [PDF]
, 2004 Volcanic SO2 can affect the Earth's environment. Where no direct measurements of SO2 in the atmosphere are available, a petrologic method of assessing sulfur release from the magma must be used.
