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 …

The Earth's history is punctuated by large explosive eruptions that eject large quantities of
magma and silicate rock fragments into the atmosphere. These tephra particles can …

Rhyolite magma has fuelled some of the Earth's largest explosive volcanic eruptions. Our
understanding of these events is incomplete, however, owing to the previous lack of directly …

After 54 years since its last major eruption in 1961, Calbuco Volcano (Ensenada, Southern
Chile) reawakened with few hours of warning on 22 April 2015 at 18: 05 local time. The main …

Eruptive column models are powerful tools for investigating the transport of volcanic gas and
ash, reconstructing past explosive eruptions, and simulating future hazards. However, the …

Abstract On May 1st 2008 Mount Chaitén (southern Chile) interrupted a long period of
quiescence, generating a sequence of explosive eruptions and causing the evacuation of …

Several lines of evidence have previously been used to suggest that ice retreat after the last
glacial maximum (LGM) resulted in regionally-increased levels of volcanic activity. It has …

The most viscous volcanic melts and the largest explosive eruptions on our planet consist of
calcalkaline rhyolites,. These eruptions have the potential to influence global climate. The …

Mediante mapeo geológico y muestreo, análisis fotogramétrico de fotografías aéreas
oblicuas y modelos de elevación digital, se documenta la secuencia eruptiva 2008-2009 del …

Abstract The Southern and Austral Volcanic Zones of the Andes comprise 74 volcanic
centres with known post-glacial activity. At least 21 of these have had one or more large …
