What happens to in-soil Radon activity during a long-lasting eruption? Insights from multidisciplinary data analysis
Editors’ Highlights— This paper considers variations of the level of the gas, Radon, in the soil of a specific volcanic area during a period of intense eruptive activity. The authors present empirical data collected during lava emissions at Mount Etna over almost a year (2008-2009), and show how a.... more
Can Volcanic Gas Levels Predict an Eruption?
From Eos.org: Research Spotlights— Researchers test whether the changing composition of volcanic gas can signal a coming eruption in Chile’s Villarrica volcano. Before a volcano erupts, there are usually signs of what’s to come; small earthquakes, heat emission, and ground swelling, to name a few,.... more
Evolution of the South Pacific Helium Plume over the Past 3 Decades
Editor's Highlight— It is not often that there are opportunities to see whether solute distributions in the ocean are in steady state over a three-decade timescale. The continuing work of these authors over most of their careers has produced data of exceptional quality that allows the issue of steady.... more
The dynamical control of subduction parameters on surface topography
Editor’s Highlight— This study highlights many of the dynamic factors that determine topography at subduction zones. The authors use numerical models of subduction to investigate the primary controls on subduction induced topography, particularly the “dynamic” component arising from stresses/pressure.... more
What Led to the Largest Known Volcanic Eruption in Human History?
From Eos.org: Research Spotlights— A mineral-dating project at the Toba caldera in Inonesia sheds light on the science of supereruptions. In the northern part of the Indonesian island of Sumatra lies the Toba caldera, a massive crater formed by the largest known volcanic eruption ever experienced by.... more
Explaining Why Some Paleomagnetic Results Fail
From Eos.org: Research Spotlights—Reordering of mineral crystal lattice structures during laboratory heating may explain the frequent need to reject results of experiments that estimate the intensity of Earth’s past magnetic fields. The basic idea behind the field of paleomagnetism is that certain iron-bearing.... more
Bubble formation and decrepitation control the CO2 content of olivine-hosted melt inclusions
Editors’ Highlight—CO2 contents of melt inclusions (MI's) in erupted minerals can be used to estimate that depth of magma emplacement and fractionation before volcanic eruptions (among other processes). But, in the past few years, quite a few studies have begun to dig deeper into the types of processes.... more
Exploring Ancient Ocean Acidification in the Rock Record
From Eos.org: Research Spotlights—Scientists studying Earth’s ancient oceans use a new method to measure ocean acidification and its effect on extinction events. Earth’s history is dotted with major mass extinction events from various natural disasters, including climate change. Fossil evidence shows.... more
Alteration Along the Alpine Fault Helps Build Seismic Strain
From Eos.org: Research Spotlights—Detailed analysis of cores drilled through New Zealand’s most dangerous on-land fault indicates that its permeability and strength are altered by mineral precipitation between seismic events. In New Zealand, the boundary between the Australian and Pacific plates is.... more
Tracking Volcanic Bombs in Three Dimensions
From Eos.org: Research Spotlights—A new method allows researchers to precisely track in three dimensions bits of fragmented magma as they are expelled in explosive volcanic eruptions. In explosive volcanic eruptions, bits of fragmented magma can be shot through the air by the release and expansion.... more
