Monitoring volcanic ash in the atmosphere
(Spie, 2013-06)
On several occasions, volcanic eruptions in the Andes have disrupted airspace for prolonged periods. Such eruptions include those in the southern Andes at the Chaitén volcano on 6 May 2008, and at Puyehue-Cordón Caulle on ...
Volcanic ashes as a source for nitrated and oxygenated polycyclic aromatic hydrocarbon pollution
(Springer Heidelberg, 2020-05)
In this study, a novel, simple, and highly sensitive analytical procedure for the quantitative evaluation of oxygenated and nitrated polycyclic aromatic hydrocarbons in volcanic ash samples based on dispersive solid–liquid ...
Magmatic volatiles in ash leachates and environmental impact assessment of the 29-30 October 2014 phreatic eruptions of Turrialba Volcano, Costa Rica
(The International Union of Geodesy and Geophysics (IUGG), 2015)
Long-range volcanic ash transport and fallout during the 2008 eruption of Chaitén volcano, Chile
(Pergamon-Elsevier Science Ltd, 2012-03-01)
The May 2008 eruption of Chaitén volcano, Chile, provided a rare opportunity to measure the long-range transport of volcanic emissions and characteristics of a widely-dispersed terrestrial ash deposit. Airborne ash mass, ...
Fluorine surface speciation in South Andean volcanic ashes
(Elsevier Science, 2020-01)
Fresh volcanic ash samples collected during the eruptions of the Hudson (1991), Chaitén (2008), Puyehue (2011), Calbuco (2015) and Copahue (2016) volcanoes were analyzed in order to identify the fluorine (F) bearing phases. ...
Of volcanoes and insects: the impact of the Puyehue-Cordon Caulle ash-fall on populations of invasive social wasps, Vespula spp.
(Springer Tokyo, 2013-03)
Volcanic eruptions have important effects on terrestrial ecosystems. The biotic effects of volcanic ash on insect populations vary from widespread and catastrophic to subtle and localized. Volcanic eruptions may increase ...
Mapa Geológico de la Hoja Istarú
(Oficina de Defensa Civil, Dirección de Geología Minas y Petróleo, Ministerio de Industria y Comercio, 2000)
Digitalización del Mapa Geológico de la Hoja Istarú, como parte de las actividades del Proyecto "Utilización de modelaje computacional y SIG como herramientas para la gestión de riesgo por caída de ceniza proveniente del ...
Forecasting volcanic ash dispersal and coeval resuspension during the April-May 2015 Calbuco eruption
(Elsevier Science, 2016-07)
Atmospheric dispersion of volcanic ash from explosive eruptions or from subsequent fallout deposit resuspension causes a range of impacts and disruptions on human activities and ecosystems. The April-May 2015 Calbuco ...
Spectroscopic and microscopic characterization of volcanic ash from puyehue-(Chile) eruption: Preliminary approach for the application in the arsenic removal
(ELSEVIER SCIENCE BV, 2013-08)
Volcanic ash from Puyehue Cordon Caulle Volcanic Complex (Chile), emitted from June 4 2011 and deposited in Villa La Angostura at ~ 40 km of the source, was collected and analyzed by Raman spectroscopy, optical and scanning ...
