Aeolian Remobilisation of the 2011-Cordón Caulle Tephra-Fallout Deposit: Example of an Important Process in the Life Cycle of Volcanic Ash
(Frontiers Media SA, 2020-01-14)Although volcanic eruptions represent short periods in the whole history of a volcano, the large amount of loose pyroclastic material produced, combined with aeolian processes, can lead to continuous, long-lasting reworking ... -
Aeolian Remobilisation of Volcanic Ash: Outcomes of a Workshop in the Argentinian Patagonia
(Frontiers Media, 2020-11-27)During explosive volcanic eruptions, large quantities of tephra can be dispersed and deposited over wide areas. Following deposition, subsequent aeolian remobilisation of ash can potentially exacerbate primary impacts on ... -
Ash resuspension related to the 2011–2012 Cordón Caulle eruption, Chile, in a rural community of Patagonia, Argentina
(2018)The 2011–2012 Cordón Caulle eruption emitted about 1 km3 of rhyodacitic tephra. Dominant westerly winds in the region caused most of the primary tephra to deposit in neighboring Argentina. In addition to the impact of ... -
Desgaste dentario en ovinos Merino de la Patagonia Argentina, tras la erupción en Chile del Volcán Puyehue
(2015-07-25)Tras la erupción en Chile del complejo volcánico Puyehue-Cordón Caúlle, el 4 de junio de 2011 se trabajó con 13 carneros Merino adultos de 3 y 4 años de edad a los cuales se los mantuvo a campo en un potrero de 8,1 hectáreas ... -
Mass fux decay timescales of volcanic particles due to aeolian processes in the Argentinian Patagonia steppe
(Springer Nature, 2020-09)We investigate the timescales of the horizontal mass flux decay of wind remobilised volcanic particles in Argentina, associated with the tephra-fallout deposit produced by the 2011–2012 Cordón Caulle (Chile) eruption. ... -
Of volcanoes and insects: the impact of the Puyehue–Cordon Caulle ash fall on populations of invasive social wasps, Vespula spp.
(2013-03)Las erupciones volcánicas tienen importantes efectos en los ecosistemas terrestres. Los efectos bióticos de ceniza volcánica en las poblaciones de insectos varian de un generalizado y catastróficoa lo sutil y localizada. ... -
Spatial distribution of volcanic ash deposits of 2011 Puyehue-Cordón Caulle eruption in Patagonia as measured by a perturbation in NDVI temporal dynamics
(2018-03)Volcanic ash fallout is a recurrent environmental disturbance in forests, arid and semi-arid rangelands of Patagonia, South America. The ash deposits over large areas are responsible for several impacts on ecological ... -
Tormentas de ceniza volcánica en Patagonia : un peligro latente y subestimado
(2018-04)Una tormenta de ceniza volcánica puede definirse como un evento de remobilización masiva de ceniza volcánica (<2mm) a partir de la acción eólica (via suspensión, saltación y reptaje). Pero, ¿a qué nos referimos exactamente ...
