A review of volcanic ash aggregation
Most volcanic ash particles with diameters< 63μm settle from eruption clouds as particle
aggregates that cumulatively have larger sizes, lower densities, and higher terminal fall …

Review of explosive hydrovolcanism
Hydrovolcanism is a type of volcanism where magma and water interact either explosively or
non-explosively. The less frequently used term, hydromagmatism, includes all the processes …

Origin of accretionary lapilli within ground-hugging density currents: evidence from pyroclastic couplets on Tenerife
Aggregation of airborne particles is an important way in which the atmosphere is cleansed of
fine dust particles, such as following explosive eruptions and meteorite impacts. We identify …

The mafic Curacautín ignimbrite of Llaima volcano, Chile
Mafic volcanism accounts for 80% of magmas erupted on Earth. Although the majority of
these eruptions are effusive to Strombolian and fountain-fed, large explosive mafic eruptions …
