First Volcanic Plume Measurements by an Elastic/Raman Lidar Close to the Etna Summit Craters

Frontiers in Earth Science, 2018
Volcanic emissions represent a well-known hazard mainly for aviation safety that can be reduced with real time observations and characterization of eruptive activity.

From Dome to Disease: The Respiratory Toxicity of Volcanic Cristobalite [PDF]

, 2012
Exposure to fine-grained volcanic ash can potentially cause acute and chronic respiratory disease. The toxicity of ash is likely to vary depending on the type and style of eruption; eruptions at dome-forming volcanoes, in particular, can produce ash ...

Timing, origin and emplacement dynamics of mass flows offshore of SE Montserrat in the last 110 ka: implications for landslide and tsunami hazards, eruption history, and volcanic island evolution [PDF]

, 2013
Mass flows on volcanic islands generated by volcanic lava dome collapse and by larger volume flank collapse, can be highly dangerous locally and may generate tsunamis that threaten a wider area.

A new, ~4500‐year varve record and high‐resolution tephrochronology from lake Hämälänlampi, eastern Finland, provides age constraints for the Furnas C and the Glen Garry/Askja A‐2000 eruptions

Journal of Quaternary Science, EarlyView.
ABSTRACT The northern European distal cryptotephra framework is constantly developing both in terms of identification of new tephra horizons and improved age constraints for the already well‐established tephra marker horizons. However, many prehistoric tephra layers have only been dated by the radiocarbon method, with its inherent problems.

The impact of Volcanic Ash of Kelud Eruption and Manure on Availability and Magnesium Uptake of Corn in Alfisols

Sains Tanah: Journal of Soil Science and Agroclimatology, 2014
Impact of fresh volcanic ash on soil fertility is rarely studied mainly on nutrient availability, uptake and on plant growth. Fresh volcanic ash is primary mineral that takes time and agents such as organic materials to mineralized before it contribute ...

Identification and correlation of the Aso‐3 tephra in the Omaezaki area, central Japan: A valuable key stratum for the MIS 6/5 transition period

Journal of Quaternary Science, EarlyView.
ABSTRACT The Aso‐3 tephra is one of the most significant widespread marker layers from the Middle to Late Pleistocene, generated by a large caldera‐forming eruption at the Aso volcano in Kyushu, southwestern Japan. Despite its importance, a distal co‐ignimbrite ash correlative has yet to be clearly identified, primarily because although volcanic glass ...

Ensemble-Based Data Assimilation of Volcanic Ash Clouds from Satellite Observations: Application to the 24 December 2018 Mt. Etna Explosive Eruption

Atmosphere, 2020
Accurate tracking and forecasting of ash dispersal in the atmosphere and quantification of its uncertainty are of fundamental importance for volcanic risk mitigation.

Improving volcanic ash predictions with the HYSPLIT dispersion model by assimilating MODIS satellite retrievals [PDF]

Atmospheric Chemistry and Physics, 2017
Currently, the National Oceanic and Atmospheric Administration (NOAA) National Weather Service (NWS) runs the HYSPLIT dispersion model with a unit mass release rate to predict the transport and dispersion of volcanic ash.
