Tephra fall from the August 1991 eruption of Volcán Hudson affected some 100,000 km2 of Patagonia and was almost immediately reworked by strong winds, creating billowing clouds of remobilised ash, or ‘ash storms’. The immediate impacts on agriculture and rural communities were severe, but were then greatly exacerbated by continuing ash storms. This paper describes the findings of a 3-week study tour of the diverse environments of southern Patagonia affected by ash storms, with an emphasis on… 
Impacts on agriculture following the 1991 eruption of Vulcan Hudson, Patagonia: lessons for recovery
Large explosive eruptions have the potential to distribute heavy ashfalls across large areas, resulting in physical and chemical impacts on agriculture, and economic and psycho-social impacts on
Short- and long-term evacuation of people and livestock during a volcanic crisis: lessons from the 1991 eruption of Volcán Hudson, Chile
Human and livestock evacuation during volcanic crises is an essential component of volcanic risk management. This study investigates the evacuation of human and livestock populations from areas
Dynamics of volcanic ash remobilisation by wind through the Patagonian steppe after the eruption of Cordón Caulle, 2011
Despite changes over time, an inverse linear correlation between the mass transports and the mass-flux gradients was found, not linked with shear-stress partition parameters, but with the ratio: ash-fall thickness to total vegetation cover.
Impacts to agriculture and critical infrastructure in Argentina after ashfall from the 2011 eruption of the Cordón Caulle volcanic complex: an assessment of published damage and function thresholds
The 2011 Cordón Caulle (Chile) was a large silicic eruption that dispersed ashfall over 75,000 km2 of land in Central Argentina, affecting large parts of the Neuquén, Río Negro, and Chubut provinces,
Modeling volcanic ash resuspension – application to the 14–18 October 2011 outbreak episode in central Patagonia, Argentina
Abstract. Volcanic fallout deposits from the June 2011 Cordon Caulle eruption on central Patagonia were remobilized in several occasions months after their emplacement. In particular, during 14–18
Volcanic ash fall impacts
All explosive eruptions produce volcanic ash (fragments of volcanic rock < 2mm: Figure 12.1), which is then dispersed by prevailing winds and deposited as ash falls hundreds or even thousands of
Laboratory Experiments of Volcanic Ash Resuspension by Wind
Fresh volcanic eruption deposits tend to be loose, bare, and readily resuspended by wind. Major resuspension events in Patagonia, Iceland, and Alaska have lofted ash clouds with potential to impact
Volcanic Ash Resuspension in Patagonia: Numerical Simulations and Observations
Resuspension of pyroclastic deposits occurs under specific atmospheric and environmental conditions and typically prolongs and exacerbates the impact associated with the primary emplacement of tephra


Environmental assessment of 1991 Hudson volcano eruption ashfall effects on southern Patagonia region, Argentina
The August 1991 eruption of the Hudson volcano in the southern Andean volcanic zone affected an area of 1000 km in radius to the east in the Argentine Patagonic meseta. The thickness of ash ranged
Delayed sedimentary response to the A.D. 1886 eruption of Tarawera, New Zealand
Sedimentary response to tephra deposition from substantial volcanic eruptions is generally immediate and dramatic. An important exception is the A.D. 1886 eruption of Mount Tarawera, New Zealand,
Impacts of Sand Storms/Dust Storms on Agriculture
The drylands of the world are affected by moderate to severe land degradation from wind erosion and there is evidence that the frequency of sand storms/dust storms in increasing. Human induced change
Effects of Volcanic Ash on the Forest Canopy Insects of Montserrat, West Indies
Abstract The impact of ash deposition levels on canopy arthropods was studied on the West Indian island of Montserrat, the site of an ongoing volcanic eruption since 1995. Many of the island’s
Effects of scoria-cone eruptions upon nearby human communities
Scoria-cone eruptions are typically low in volume and explosivity compared with eruptions from stratovolcanoes, but they can affect local populations profoundly. Scoria-cone eruption effects vary
The 26.5 ka Oruanui eruption, New Zealand: A review of the roles of volcanism and climate in the post‐eruptive sedimentary response
Abstract The landscape response to large explosive pyroclastic volcanic eruptions is one of the most dramatic processes in sedimentology and geomorphology. Processes of post‐eruptive erosion and
Material Sources, Chemical Weathering, and Physical Denudation in the Chubut River Basin (Patagonia, Argentina): Implications for Andean Rivers
The Chubut is a medium‐size (42,000 km2) river basin that drains the arid‐to‐semiarid Patagonian seaboard and pours its waters into the southwestern Atlantic Ocean (ca. lat 43°20′S, long 65°04′W).
Sedimentological analysis of the tephra from the 12–15 August 1991 eruption of Hudson volcano
The tephra fallout from the 12–15 August 1991 explosive eruption of Hudson volcano (Cordillera de los Andes, 45°54′ S-72°58′ W; Chile) was dispersed on a narrow, elongated ESE sector of Patagonia,
