Outgassing behaviour during highly explosive basaltic eruptions

Communications Earth & Environment
Explosivity of basaltic eruptions is related to the efficiency in which exsolved gas can separate from the melt during ascent, which is controlled by magma permeability.

Potential atmospheric impact of the Toba Mega‐Eruption ∼71,000 years ago [PDF]

, 1996
An ∼6‐year long period of volcanic sulfate recorded in the GISP2 ice core about 71,100 ± 5000 years ago may provide detailed information on the atmospheric and climatic impact of the Toba mega‐eruption. Deposition of these aerosols occur at the beginning

Five Large 13th Century C.E. Volcanic Eruptions Recorded in Antarctica Ice Cores

Atmosphere
Major explosive volcanic eruptions impact the climate by altering the radiative balance of the atmosphere and through feedback mechanisms in the climate system.

Fe-rich filamentary textures reveal timescales of magmatic interaction before the onset of high-energy explosive events at basaltic volcanoes

Volcanica
Fe-rich filamentary textures are almost ubiquitous in products from explosive eruptions at basaltic volcanoes and, in particular, they characterize the groundmass of ash and lapilli emitted during high-energy events.

Ash plume properties retrieved from infrared images: a forward and inverse modeling approach

, 2014
We present a coupled fluid-dynamic and electromagnetic model for volcanic ash plumes. In a forward approach, the model is able to simulate the plume dynamics from prescribed input flow conditions and generate the corresponding synthetic thermal infrared (

Upper-atmosphere Aerosols: Properties and Natural Cycles [PDF]

, 1992
The middle atmosphere is rich in its variety of particulate matter, which ranges from meteorite debris, to sulfate aerosols, to polar stratospheric ice clouds. Volcanic eruptions strongly perturb the stratospheric sulfate (Junge) layer.
