Vegetation dieback as a proxy for temperature within a wet pyroclastic density current: A novel experiment and observations from the 6th of August 2012 Tongariro eruption [PDF]
, 2014 The 6th of August 2012 eruption of Te Maari (Mt Tongariro, New Zealand) generated wet pyroclastic density currents (PDCs) which caused widespread dieback of vegetation (singed, brown foliage) in their path.

A stress-controlled mechanism for the intensity of very large magnitude explosive eruptions [PDF]
, 2011 Large magnitude explosive eruptions are the result of the rapid and large-scale transport of silicic magma stored in the Earth's crust, but the mechanics of erupting teratonnes of silicic magma remain poorly understood.

Dynamics of solar coronal eruptions [PDF]
Journal of Geophysical Research: Space Physics, 2001 The kinematics of 87 solar eruptive events (flare sprays, eruptive prominences, and coronal transients) observed above the solar limb are studied. The data reveal a clear statistical trend for the highest measured value of the acceleration to be lower in the events taking place at a larger radial distance.

Geochemistry, Geophysics, Geosystems, 2007 The explosive eruption of voluminous silicic magmas often produces widespread and massive deposits formed from pyroclastic density currents. While these punctuated events dramatically alter the landscape and have potential climate‐altering impact, our ...

Supergranular-scale magnetic flux emergence beneath an unstable filament [PDF]
, 2015 Here we report evidence of a large solar filament eruption on 2013, September 29. This smooth eruption, which passed without any previous flare, formed after a two-ribbon flare and a coronal mass ejection towards Earth.

The dynamics of an erupting prominence [PDF]
Astronomy & Astrophysics, 2002 H α full disk observations and radio interferometry at decimetre and metre wavelengths are used to probe the dynamics of ejecta and electron acceleration during a solar eruptive event on 1990 September 14. An erupting prominence and a moving type IV radio source are shown to trace a common magnetic structure during its rise from ~10 Mm to 3 $R_\odot ...

Explosive Behavior of Intermediate Magmas: The Example of Cotopaxi Volcano (Ecuador)
Geochemistry, Geophysics, Geosystems, 2021 The variability in intensity and style shown by explosive volcanism has been traditionally explained by a complex interplay among melt composition and pre‐eruptive volatile content, which modulate magma ascent and conduit dynamics. However, magmas having

A multidisciplinary study of an exceptional prehistoric waste dump in the mountainous inland of Calabria (Italy) : implications for reconstructions of prehistoric land use and vegetation in Southern Italy [PDF]
, 2020 The mountainous inland of northern Calabria (Southern Italy) is known for its sparse prehistoric human occupation. Nevertheless, a thorough multidisciplinary approach of field walking, geophysical survey and invasive research led to the discovery of a ...

Maars to calderas. End-members on a spectrum of explosive volcanic depressions [PDF]
, 2015 We discuss maar-diatremes and calderas as end-members on a spectrum of negative volcanic landforms (depressions) produced by explosive eruptions (note—we focus on calderas formed during explosive eruptions, recognizing that some caldera types are not ...
