Investigating the nature of an ash cloud event in Southern Chile using remote sensing: volcanic eruption or resuspension?
(Taylor & Francis, 2017-02)
On 14 December 2013, the Cooperative Institute for Meteorological Satellite Studies (United States) reported a volcanic ash cloud apparently emitted by the Puyehue Cordón Caulle Volcanic Complex (Chile) and indicated its ...
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 ...
Modeling volcanic ash resuspension - Application to the 14-18 October 2011 outbreak episode in central Patagonia, Argentina
(Copernicus Publications, 2014-01)
Volcanic fallout deposits from the June 2011 Cordón Caulle eruption on central Patagonia were remobilized in several occasions months after their emplacement. In particular, during 14-18 October 2011, an intense outbreak ...
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 ...
Aeolian Remobilisation of Volcanic Ash: Outcomes of a Workshop in the Argentinian Patagonia
(Frontiers Media S.A., 2020-11)
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 ...
Aeolian remobilisation of volcanic ash: outcomes of a workshop in the Argentinian Patagonia
(Frontiers MediaCH, 2020-11)
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 ...

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 ...
