Wind-remobilisation processes of volcanic ash. Consensual Document
(University of GenevaAR, 2020-02)
Explosive volcanic eruptions can eject large quantities of tephra into the atmosphere that can be dispersed and deposited over wide areas. Whilst the hazardous consequences of primary tephra fallout are well known, subsequent ...
Consequences of Volcanic Ash Deposition on the Locomotor Performance of the Phymaturus spectabilis Lizard from Patagonia, Argentina
(Wiley, 2013-12)
The locomotor performance of lizards depends on their morphological and physiological adaptations to the habitat. However, when the habitat changes dramatically, for example by a volcanic eruption, the performance of lizards ...
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 ...
The effect of dynamic loading on the shear strength of pyroclastic Ash Deposits and implications for landslide hazard: The case of Pudahuel Ignimbrite, Chile
(Elsevier, 2016)
The co-seismic and post-seismic behaviour of pyroclastic ash deposits and its influence on slope stability remains as a challenging subject in engineering geology. Case studies in volcanic areas of the world suggest that ...
Distribution, mineralogy, petrography, provenance and significance of Permian ash-carrying deposits in the Paraná BasinDistribution, mineralogy, petrography, provenance and significance of Permian ash-carrying deposits in the Paraná Basin
(Universidade de São Paulo, Instituto de Geociências, 2005)
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 ...
Assessing the magnitude of impact of volcanic ash deposits on Merino wool production and fibre traits in the context of a drought in North-west Patagonia, Argentina
(CSIRO Publishing, 2014-02)
Environmental variability is a key feature of arid and semiarid rangelands worldwide. Drought is one of the main sources of variation in most extensive livestock production systems in arid environments, with biophysical ...
Effects of volcanic ash deposition on the early recovery of gap vegetation in Northwestern Patagonian steppes
(Academic Press Ltd - Elsevier Science Ltd, 2015-11)
Volcanic eruptions can cause changes in plant communities through the effects of ash fall. We studied the effect of ash deposition on vegetation recovery in inter-plant patches (gaps) following the eruption of the ...
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, ...
Dynamics of volcanic ash remobilisation by wind through the Patagonian steppe after the eruption of Cordón Caulle, 2011
(Nature Publishing Group, 2017-03)
Wind erosion of freshly-deposited volcanic ash causes persistent storms, strongly affecting ecosystems and human activity. Wind erosion of the volcanic ash was measured up to 17 months after the ash deposition, at 7 sites ...
