Generation of volcanic ash by basaltic volcanism [PDF]

open access: yesJournal of Geophysical Research: Solid Earth, 2012
The recent eruptions of Eyjafjallajökull and Grimsvötn volcanoes in Iceland demonstrate the importance of a better understanding of processes leading to the formation of volcanic ash, specifically of fine volcanic ash that poses a threat to air traffic.

Spectroscopic study of volcanic ashes

open access: yesJournal of Hazardous Materials, 2020
Volcanic ashes particles are subjected to substantial modification during explosive eruptions. The mineralogical and compositional changes have important consequences on the environment and human health. Nevertheless, the relationship between the speciation of iron (Fe) and the mineralogical composition and particle granulometry of the ashes, along ...

Deposition behaviour and its damage evaluation of natural volcanic ash deposited under a high temperature and a high gas flow condition

open access: yesNihon Kikai Gakkai ronbunshu, 2016
Japan has a special feature that there are a lot of natural disasters compared with other country. The volcanic explosion which has occurred at the Ontake-mountain in 2012 was enormous. Recently, the volcanic explosion at Mt. Fuji has been paid attention.

A re-assessment of historical records pertaining to the activity of Mt. Baekdu (Paektu, Tianchi) volcano

open access: yesGeoscience Letters, 2023
This study re-assesses the historical records pertaining to the activity of Mt. Baekdu according to volcanic phenomena. We categorized volcanic phenomena into five categories: rumbling, atmospheric abnormality, ash rain, ash cloud and phenomenon ...

Volcanic ash detection with infrared limb sounding: MIPAS observations and radiative transfer simulations [PDF]

open access: yesAtmospheric Measurement Techniques, 2014
Small volcanic ash particles have long residence times in the troposphere and the stratosphere so that they have significant impact on the Earth's radiative budget and consequently affect climate.

Applying volcanic ash to croplands – The untapped natural solution

open access: yesSoil Security, 2021
A nature-based soil security solution is proposed. In countries with active volcanoes, such as Indonesia, volcanic ash could be used to supply nutrients and reduce CO2 from the atmosphere.

Four-dimensional distribution of the 2010 Eyjafjallajökull volcanic cloud over Europe observed by EARLINET [PDF]

open access: yes, 2012
The eruption of the Icelandic volcano Eyjafjallajökull in April–May 2010 represents a "natural experiment" to study the impact of volcanic emissions on a continental scale.

Health Impact Assessment of Volcanic Ash Inhalation: A Comparison With Outdoor Air Pollution Methods

open access: yesGeoHealth, 2020
This paper critically appraises the extrapolation of concentration‐response functions (CRFs) for fine and coarse particulate matter, PM2.5 and PM10, respectively, used in outdoor air pollution health impact assessment (HIA) studies to assess the extent ...

Volcanic Ash and Small Uncrewed Aerial Vehicle (sUAV) Interaction: In-situ Observations and Laboratory Experiments on Aircraft Failure

open access: yesFrontiers in Earth Science, 2022
The deployment of small uncrewed aerial vehicles (sUAVs) for volcanological applications has grown over the last decade, mainly attributed to the development of affordable, smaller, and versatile platforms.

Heterogeneous Ice Nucleation by Soufriere Hills Volcanic Ash Immersed in Water Droplets. [PDF]

open access: yesPLoS ONE, 2017
Fine particles of ash emitted during volcanic eruptions may sporadically influence cloud properties on a regional or global scale as well as influencing the dynamics of volcanic clouds and the subsequent dispersion of volcanic aerosol and gases.
