Prediction of landslide occurrence in urban areas located on volcanic ash soils in Pereira, Colombia
(Springer Verlag, 2004-01-01)
As a result of the 25 January 1999 Armenia earthquake, the city of Pereira (400,000 inhabitants), located on a volcanic ash-covered alluvial fan in the western limit of the Central Cordillera (Colombia), suffered 250 slope ...
Volcanic ash as flux in clay based triaxial ceramic materials, effect of the firing temperature in phases and mechanical properties
(Elsevier, 2015-06)
The study of possible incorporation of nontraditional starting powders is a contribution to the rational utilization of raw materials in the ceramic industry. The technological properties of solid waste problems (both urban ...
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 ...
Phase transition process in the hydrothermal zeolitization of volcanic ashes into LTA and FAU structures
(Clay Minerals Society, 2021-10-19)
Minerals such as quartz, present widely in various volcanic ashes, remain unaltered throughout the low-temperature hydrothermal process currently used in industry to obtain zeolites, causing an incomplete hydrothermal ...
Volcanic ash forecast using ensemble-based data assimilation: an ensemble transform Kalman filter coupled with the FALL3D-7.2 model (ETKF–FALL3D version 1.0)
(Geoscientific Model Development, 2020)
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 ...
