Growth and evolution of long-lived, large volcanic clusters in the Central Andes: The Chachani Volcano Cluster, southern Peru
(ElsevierNL, 2022-06)
In the Central Andes, large (> 500 km2) and long-lived (1–5 Ma) volcanic clusters (LVCs) are less explored and their eruptive history and magmatic regimes less understood than smaller, short-lived (<0.5 Ma), individual ...
Arsenic in Latin America: A critical overview on the geochemistry of arsenic originating from geothermal features and volcanic emissions for solving its environmental consequences
(Elsevier B.V.NL, 2020-05)
Geothermal fluids and volcanic emissions are important sources of arsenic (As), resulting in elevated concentrations of As in ground-, surface-water and soil, which may adversely affect the environment. Arsenic originating ...
Ubinas: the evolution of the historically most active volcano in southern Peru
(Springer-VerlagDE, 2005-07)
Ubinas volcano has had 23 degassing and ashfall episodes since A.D. 1550, making it the historically most active volcano in southern Peru. Based on fieldwork, on interpretation of aerial photographs and satellite images, ...
Multidisciplinary Study of the Impacts of the 1600 CE Huaynaputina Eruption and a Project for Geosites and Geo‑touristic Attractions
(SpringerUS, 2021-07)
The Huaynaputina volcano, southern Peru, was the site of the largest historical eruption (VEI 6) in the Andes in 1600 CE, which occurred during the historic transition between the Inca Empire and the Viceroyalty of Peru. ...
Shallow magma convection evidenced by excess degassing and thermal radiation during the dome-forming Sabancaya eruption (2012–2020)
(Springer Berlin HeidelbergUS, 2022-02)
We used a large set of satellite- (visible, infrared, and radar images from Planetscope, MODIS, VIIRS, Sentinel2, Landsat 8, and Sentinel 1) and ground-based data (optical images, SO2 flux, shallow seismicity) to describe ...
Linking magmatic processes and magma chemistry during the post-glacial to recent explosive eruptions of Ubinas volcano (southern Peru)
(Elsevier B.V.NL, 2020-12)
Understanding the links between the magma differentiation processes, the magma plumbing system and the magma composition at arc volcanoes is of paramount importance for volcanic hazard assessment. In this work we focus on ...
Magma extrusion during the Ubinas 2013–2014 eruptive crisis based on satellite thermal imaging (MIROVA) and ground-based monitoring
(ElsevierNL, 2015-09)
After 3 years of mild gases emissions, the Ubinas volcano entered in a new eruptive phase on September 2nd, 2013. The MIROVA system (a space-based volcanic hot-spot detection system), allowed us to detect in near real time ...
The Tutupaca volcanic complex (Southern Peru): Eruptive chronology and successive destabilization of a dacitic dome complex
(ElsevierUS, 2021-08)
Several processes have been proposed as triggering mechanisms for the large sector collapses that affect most volcanoes, and which may occur several times in the volcano's lifetime. Here we present and discuss the case of ...
Erupciones históricas del Volcán Tromen: análisis geomorfológico y geocronológico en su sector noroesteHistoric eruption of Tromen volcano: Geomorphologic and geochronological analysis on its northwestern area
(Asociación Geológica Argentina, 2014-06)
Se estudiaron los productos más jóvenes del volcán Tromen en su sector NO. En base al análisis de reportes históricos en conjunto con datos geomorfológicos y una edad radiocarbono, se determinó que los últimos períodos de ...
Estratigrafía y evolución del Complejo Volcánico Cerro Blanco, Puna Austral, Argentina
(Universidad Nacional Autónoma de México. Centro de Geociencias, 2015-03)
El Complejo Volcánico Cerro Blanco se ubica en la provincia de Catamarca en el extremo sur del altiplano Andino y ha sido interpretado como un sistema de calderas anidadas con abundantes depósitos piroclásticos y actividad ...
