TL;DR: Investigations of an Icelandic volcanic eruption confirm that sulfate aerosols caused a discernible yet transient brightening effect, as predicted, but their effect on the liquid water path was unexpectedly negligible.
Journal ArticleDOI
Reconstructing the deep CO2 degassing behaviour of large basaltic fissure eruptions
TL;DR: In this article, the mass of volatiles degassed from volcanic eruptions is estimated by comparing the volatile concentrations in undegassed glassy melt inclusions with the volatile concentration in the degassed matrix glass.
Journal ArticleDOI
Tracking the changing oxidation state of Erebus magmas, from mantle to surface, driven by magma ascent and degassing
Yves Moussallam,Clive Oppenheimer,Bruno Scaillet,Fabrice Gaillard,Philip R. Kyle,Nial Peters,Margaret E. Hartley,Kim Berlo,Amy Donovan +8 more
TL;DR: In this paper, the authors track the redox evolution of an alkaline magmatic suite at Erebus volcano, Antarctica, from the mantle to the surface, using X-ray absorption near-edge structure (XANES) spectroscopy at the iron and sulphur K-edges.
Journal ArticleDOI
Magma fragmentation in highly explosive basaltic eruptions induced by rapid crystallization
Fabio Arzilli,Giuseppe La Spina,Mike Burton,Margherita Polacci,Nolwenn Le Gall,Margaret E. Hartley,Danilo Di Genova,Biao Cai,Nghia T. Vo,Emily C. Bamber,Sara Nonni,Robert C. Atwood,Edward W. Llewellin,Richard A. Brooker,Heidy M Mader,Peter D. Lee +15 more
TL;DR: In this paper, a numerical model was used to investigate the minimum viscosity required for the fragmentation of fast ascending basaltic magmas, and it was shown that the critical requirements are initial magma temperatures lower than 1,100˚°C to reach a syn-eruptive crystal content of over 30˚vol%, and thus a magma viscoverage around 105˚Pa.
Journal ArticleDOI
The 1874–1876 volcano-tectonic episode at Askja, North Iceland: Lateral flow revisited
TL;DR: The Edinburgh Ion Microprobe Facility (MEH) as mentioned in this paper was funded by NERC grant IMF386/1109 and MEH was supported by NE/F008929/1.
