The Planchón-Peteroa Volcanic Complex (PPVC) is located in the Central Andes, Argentina-Chile. Even though this active volcanic system is considered one of the most dangerous volcanoes in the region, with more than twenty ...

Hudson volcano (Chile) is the southern most stratovolcano of the Andean Southern Volcanic Zone and has produced some of the largest Holocene eruptions in South America. There have been at least 12 recorded Holocene explosive ...

The August 1991 eruptions of Hudson volcano produced ∼2.7 km3 (dense rock equivalent, DRE) of basaltic to trachyandesitic pyroclastic deposits, making it one of the largest historical eruptions in South America. Phase 1 ...

This contribution presents a numerical model of time-dependent physical processes and differentiation in a cooling magma chamber to obtain the magma and liquid composition and model the distribution of minerals and H2O ...

El Complejo Volcánico Nevados de Chillán (NdC), localizado en los Andes del Sur, es un sistema volcánico controlado estructuralmente que presenta un nutrido registro de actividad eruptiva y que inició su más reciente ciclo ...

Rhyolite is the most viscous of liquid magmas, so it was surprising that on 2 May 2008 at Chaitén Volcano, located in Chile’s southern Andean volcanic zone, rhyolitic magma migrated from more than 5 km depth in less than ...

The Sierra Valle Fértil Complex of west-central Argentina represents a section of the Ordovician (~470 Ma) Famatinian arc and exposes a continuous, tilted crustal arc section ranging in depth from ~12 to 32 km (~4-8 kbar ...

Cordón Caulle in southern Chile has produced three dacitic to rhyolitic fissure eruptions over the past century (in 1921–1922, 1960 and 2011–2012), and thereby provides an ideal opportunity to examine the architecture of ...

Lascar (5592 m a.s.l.) and Lastarria (5697 m a.s.l.) are Chilean active stratovolcanoes located in the Central Volcanic Zone (CVZ; 16 degrees S to 28 degrees S) that have developed on top of a 71 km thick continental crust. ...
