Selective measurement of volcanic ash flow-rate
2013 IEEE International Instrumentation and Measurement Technology Conference (I2MTC), 2013The ash fall-out, following explosive activity of volcanoes, represents a relevant factor of risk for people and a serious hazard for air traffic. Researchers at DIEEI of the University of Catania are facing the challenge of developing a low-cost multisensor system for the monitoring of ash fall-out phenomena with particular regards to average ...

Inorganic Phosphorus Forms in Soufrière Hills Volcanic Ash and Volcanic Ash-Derived Soil
Soil Science, 2009Abstract Soufriere Hills volcano is an active andesitic volcano located in the south-central part of Montserrat Island, West Indies. Phosphorus (P)-rich ash emitted from the Soufriere Hills volcano is expected to have effects on P retention and distribution in highly acidic soils surrounding the areas inundated with ash for several years.

Location and Extent of the Deposits The volcanic ash or dust in the Great Plains region was first recognized by Wadsworth, who in 1884 described deposits of such material that lie between the White and Niobrara rivers. 3 Four years earlier Aughey 4 erroneously identified similar material as geyserite, and that name persisted in the literature for ...
