Ash aggregation is a common phenomenon in particle-laden environments of volcanic eruption plumes and pyroclastic density currents. Many of these initially fragile aggregates gain sufficient mechanical strength to remain intact after atmospheric transport and deposition. Several processes contribute to ash aggregate stability, including electrostatic and hydrostatic bonding, ice formation, and cementation by salt precipitates. Here, we compare leachate chemistry from aggregates from a variety… Expand

Influence of particle aggregation on the tephra dispersal and sedimentation from the October 8, 2016, eruption of Aso volcano
The phreatomagmatic eruption at Aso volcano on October 8, 2016, released PDC and fallout up to 320 km from the vent, providing an opportunity to study the dispersal and sedimentation of tephraExpand
Anak Krakatau triggers volcanic freezer in the upper troposphere
It is shown that this unprecedented event was caused and sustained by phreatomagmatic activity at Anak Krakatau volcano, Indonesia during 22–28 December 2018 and that lightning flash rates were strongly correlated with satellite-derived plume heights for this event. Expand


Ash aggregation enhanced by deposition and redistribution of salt on the surface of volcanic ash in eruption plumes
The data suggest that volcanically-relevant loads of surface salts can be produced by acid condensation in eruptive settings and the role of liquids in re-distributing surface salts and cementing ash aggregates offers further insight into the mechanisms which preserve well-structured aggregates in some ash deposits.

Experimental volcanic ash aggregation: Internal structuring of accretionary lapilli and the role of liquid bonding
Explosive volcanic eruptions can release vast quantities of pyroclastic material into Earth's atmosphere, including volcanic ash, particles with diameters less than two millimeters. Ash particles canExpand
A review of volcanic ash aggregation
Most volcanic ash particles with diameters <63 lm settle from eruption clouds as particle aggregates that cumulatively have larger sizes, lower densities, and higher terminal fall velocities thanExpand
Aggregation in particle rich environments: a textural study of examples from volcanic eruptions, meteorite impacts, and fluidized bed processing
Investigating aggregates from 18 natural deposits as well as aggregates produced experimentally via fluidized bed techniques proves that in all three environments, aggregation occurs under broadly similar conditions despite the significant differences in source conditions. Expand
Experimental investigation of volcanic particle aggregation in the absence of a liquid phase
[1] Understanding the dispersal and deposition of fine-grained silicate particles from volcanic plumes is key to interpreting ash fall deposits and predicting hazards for future eruptions. It isExpand
Stability of volcanic ash aggregates and break-up processes
This experimental study uses industrial granulation techniques to artificially produce aggregates and finds a dependence of aggregate stability on primary particle size distribution and solid particle binder concentration, which could be combined with eruption source parameters and implemented in future tephra dispersal models.

Aggregation-dominated ash settling from the Eyjafjallajökull volcanic cloud illuminated by field and laboratory high-speed imaging
The recent Eyjafjallajokull (Iceland) eruption strikingly underlined the vulnerability of a globalized society to the atmospheric dispersal of volcanic clouds from even moderate-size eruptions. AshExpand
Growth of volcanic ash aggregates in the presence of liquid water and ice: an experimental approach
Key processes influencing the aggregation of volcanic ash and hydrometeors are examined with an experimental method employing vibratory pan aggregation. Mechanisms of aggregation in the presence ofExpand
In situgranulation by thermal stress during subaqueous volcanic eruptions
Some of the most complex volcanic thermodynamic processes occur when erupting magma interacts with water. In shallow water, “Surtseyan” eruptions are spectacular, and they efficiently fragment magmaExpand

Abstract The vent-hosted hydrothermal system of Ruapehu volcano is normally covered by a c. 10 million m3 acidic crater lake where volcanic gases accumulate. Through analysis of eruptionExpand
