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
(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 ...
The lifecycle of volcanic ash: advances and ongoing challenges
(Springer, 2022-05)
Explosive volcanic eruptions can produce vast amounts of volcanic ash made up mainly of fragments of magmatic glass, country rock and minerals<2 mm in size. Ash particles forming from magma fragmentation are generated by ...
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 ...
Characterization of the ashes from the 2014-2015 Turrialba Volcano eruptions by means of scanning electron microscopy and energy dispersive x-ray spectroscopy
(2016)
The Turrialba Volcano is a stratovolcano located approximately 35 km northwest from San José, Costa Rica’s capital city. Since October 29, 2014, until at least late 2015, a series of eruptions has represented ...

Comparison of lake and land tephra records from the 2015 eruption of Calbuco volcano, Chile
(Springer Verlag, 2019)
Tephra layers in lake sediment cores are regularly used for tephrostratigraphy as isochronous features for dating and recording eruption frequencies. However, their value for determining volcanic eruption size and style ...
Largest explosive eruption in historical times in the Andes at Huaynaputina volcano, A.D. 1600, southern Peru
(Geological Society of America, 1999-05)
The largest explosive eruption (volcanic explosivity index of 6) in historical times in the Andes took place in a.d. 1600 at Huaynaputina volcano in southern Peru. According to chronicles, the eruption began on February ...
