Petrographic analysis of the volcanic bombs and blocks from Poás Volcano: April-June 2017 eruptive period
(2017-09)
During the first semester of 2017, Poás Volcano, in the Central American Volcanic Arc (CAVA) initiated a period of volcanic unrest that included high energy phreatomagmatic and magmatic eruptions. The most notable erup-tions ...
Manizales frente a la coyuntura volcánica
(2012-04-16)
Esta nota señala las amenazas volcánicas más probables que debe atender Manizales, donde equivocadamente se piensa en sismos intensos que a 30 km del volcán se atenúan, y entonces las evacuaciones no proceden, máxime cuando ...
Intimidades del Ruiz para un examen de la amenaza volcánica
(2012-03-19)
Sí lo normal del Ruiz como volcán activo es erupcionar, parece sensato esperar eventos cuyo alcance espacial se aproxime a las previsiones señaladas en su mapa de amenazas, dado que la erupción del 13 de noviembre de 1985 ...
Modelado de la última erupción volcánica del Complejo Volcánico Puyehue-Cordón CaulleModeling of last eruption from Puyehue-Cordon Caulle volcanic complex
(Universidad de Atacama, 2013-10)
El presente trabajo está centrado en la utilización y validación del modelo Euleriano FALL3D para la simulación de la dispersión de aerosoles, durante la erupción del complejo volcánico Puyehue-Cordón Caulle, ocurrida el ...
Global and Direct UV Irradiance Variation in the Nahuel Huapi National Park (Patagonia, Argentina) After the Eruption of Puyehue- Cordon Caulle (Chile)
(Elsevier, 2014-02-25)
On June 4th, 2011, the Puyehue-Cordon Caulle volcanic complex (40ª35´25′′S 72ª07´02′′W, Chile) started eruption, sending ash 45,000 feet into the atmosphere. After the initial period, the eruption continued for several ...
The eruptive chronology of the Yucamane-Calientes compound volcano: A potentially active edifice of the Central Andes (southern Peru)
(Elsevier B.V.NL, 2020-03)
We reconstruct the eruptive chronology of the Yucamane–Calientes compound volcano in southern Peru based on extensive fieldwork and a large dataset of geochronological (K-Ar, 40Ar/39Ar, U-Pb, and 14C) and geochemical (major ...
The eruptive chronology of the Ampato-Sabancaya volcanic complex (Southern Peru)
(ElsevierNL, 2016-09)
We have reconstructed the eruptive chronology of the Ampato-Sabancaya volcanic complex (Southern Peru) on the basis of extensive fieldwork, and a large dataset of geochronological (40K-40Ar,14C and3He) and geochemical ...
The 2006 - 2009 activity of the Ubinas volcano (Peru): Petrology of the 2006 eruptive products and insights into genesis of andesite magmas, magma recharge and plumbing system
(ElsevierNL, 2014-01)
Following a fumarolic episode that started six months earlier, the most recent eruptive activity of the Ubinas volcano (south Peru) began on 27 March 2006, intensified between April and October 2006 and slowly declined ...
