Quiet Sun Explosive Events: Jets, Splashes, and Eruptions
, 2012 Explosive events are small transition region phenomena characterised by broad non-Gaussian wings in their line profiles. Images from the Solar Dynamics Observatory (SDO) give a first view of the plasma dynamics at the sites of explosive events seen in O ...

Global Change Biology Communications, EarlyView.Climate change has rapidly expanded and shifted suitable climate conditions for eight major forest pests across North America, especially toward northern and higher elevation areas. Host exposure and overlap among pests are increasing, raising ecological and economic risks, and signaling accelerating future impacts under continued warming.

Report on potential sampling biases in the LaMEVE database of global volcanism
Journal of Applied Volcanology, 2017 We investigate whether the disproportionate contribution of individual volcanoes in the Large Magnitude Explosive Volcanic Eruption database (LaMEVE) potentially compromises the treatment of LaMEVE as a globally representative database of volcanic ...

Role of volatiles in highly explosive basaltic eruptions
Communications Earth & Environment, 2022 The increase in mass eruption rate due to the presence of volatiles in explosive basaltic eruptions is greatly dependent on the type of volatile, according to numerical modelling. CO2 has a very limited effect unless injected from an external source.

Volcano remote sensing with ground-based spectroscopy [PDF]
, 2005 The chemical compositions and emission rates of volcanic gases carry important information about underground magmatic and hydrothermal conditions, with application in eruption forecasting.

Macromolecular Materials and Engineering, EarlyView.Multiscale experiments and DFT calculations establish how polyimide precursor choice governs additively manufactured morphology. PMDA/ODA and PMDA/DDS printed via a polysalt vat photopolymerization route are compared by SEM, SAXS/WAXS, and TGA. PDMA/DDS displays reduced π‐stacking and lower thermal stability compared to PMDA/ODA.

Rapid laccolith intrusion driven by explosive volcanic eruption
Nature Communications, 2016 Magmatic intrusions and volcanic eruptions are intimately related phenomena. Shallow magma intrusion builds subsurface reservoirs that are drained by volcanic eruptions. Thus, the long-held view is that intrusions must precede and feed eruptions. Here we

The 15 January 2022 Hunga Tonga Eruption History as Inferred From Ionospheric Observations
Geophysical Research Letters, 2022 On 15 January 2022, the Hunga Tonga‐Hunga Ha’apai submarine volcano erupted violently and triggered a giant atmospheric shock wave and tsunami. The exact mechanism of this extraordinary eruptive event, its size and magnitude are not well understood yet ...

Gender &History, EarlyView.Abstract This article investigates the ways in which late‐nineteenth‐century students at Northwestern University's Cumnock School of Oratory mobilised elocution training and parlour performance to foster mixed‐gender public discourse. I use student publications to reconstruct parlour meetings in which women and men adapted traditions of conversational ...
