Regardless of the recent advances in geophysical monitoring and real-time quantitative
observations of explosive volcanic eruptions, the characterization of tephra deposits remains …

It is increasingly recognized that the gravitational stability of explosive eruption columns is
governed by complex ash-pumice-gas (multiphase) interactions as well as the mechanics of …

In explosive submarine eruptions, volcanic jets transport fragmented tephra and exsolved
gases from the conduit into the water column. Upon eruption the volcanic jet mixes with …

The Ecuadorian arc is composed of an unusually high number of volcanoes, organized as
along-arc alignments and across-arc clusters, in a relatively small area. Although several …

A new, pre-Green Tuff (46 ka) volcanic stratigraphy is presented for the peralkaline
Pantelleria Volcano, Italy. New 40Ar/39Ar and paleomagnetic data are combined with …

The distribution of clasts deposited around a volcano during an explosive eruption typically
contoured by isopleth maps provides important insights into the associated plume height …

Cotopaxi volcano, situated in the Eastern Cordillera of the Ecuadorian Andes, is one of the
most active volcanoes on Earth. The volcano is well known for the magnificence of its almost …

A multiphase fluid dynamic model is used to explore the effects of entrainment of granular
debris into sustained volcanic jets such as those which produce sub-Plinian to Plinian …

There are hundreds of volcanic lakes around the world that represent an important hazard
due to the potential occurrence of phreatomagmatic or limnic eruptions. Variations in …

Volcanic tephra fall deposits, which form during explosive eruptions, are commonly
characterized in terms of their thickness and grainsize. While significant efforts have been …
