Pyroclastic density currents with an abundance of cauliflower-shaped bombs are an uncommon type of deposit, called bomb and ash flow (BoAF) deposits in several papers. Although they are similar to block and ash flow (BAF) deposits (e.g., rich in juvenile...

One of the most outstanding features of the Southern Puna is the occurrence of a widespread monogenetic mafic volcanism during Neogene-Quaternary. Despite a number of published papers focusing on the petrogenesis of this back-arc volcanism, works aimed o...

Basaltic activity is the most common class of volcanism on Earth, characterized by magmas of sufficiently low viscosities such that bubbles can move independently of the melt. Following exsolution, spherical bubbles can then expand and/or coalesce to gen...

The Tungurahua volcano (Northern Andean Volcanic Zone) has been erupting since 1999, with at least
four eruptive phases up to present. Although a dozen of research focuses in tephra fall deposits during this period, none
of them cover the full eruptive c...

INTRODUCTION. On May 17, at about 6:00 a.m., the Llaima volcano began a strombolian eruption, 10 years since the last short phreatomagmatic eruption (April 1984). The Llaima volcano is a complex composite-shield volcano, with a buried caldera and 40 para...
