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 ...
Immobilization and stabilization of volcanic ash in soil aggregates in semiarid meadows of Northern Patagonia
(Elsevier, 2021-06-15)
Although volcanism may be perceived by the society as a phenomenon with mostly negative consequences, this is not always the case especially for natural systems. There is a limited knowledge on how the deposited pristine ...
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 ...
Spatial distribution of volcanic ash deposits of 2011 Puyehue-Cordón Caulle eruption in Patagonia as measured by a perturbation in NDVI temporal dynamics
(Elsevier Science, 2018-03-15)
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 ...
Encounters with the volcano: community knowledge exchange on responses to impacts to volcanic ash in Ecuador and Peru
(Istituto Nazionale di Geofisica e VulcanologiaITA, 2018)
In recent years, innovative methodologies to communicate volcanic hazards and risk have been developed through film, art and past narratives of volcanic eruptions. At the same time, it has been recognised that understanding ...
