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.

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.

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 ...

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 ...

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.

Mechanical and durability performance of sustainable concretes containing conventional and emerging supplementary cementitious materials

open access: yesDevelopments in the Built Environment, 2023
This paper presents a comparative study on the mechanical and durability properties of concrete mixtures containing conventional supplementary cementitious materials (SCMs) and emerging alternatives (i.e., volcanic ash, volcanic ash-limestone blend, and ...

A Multi-Sensor Approach for Volcanic Ash Cloud Retrieval and Eruption Characterization: The 23 November 2013 Etna Lava Fountain

open access: yesRemote Sensing, 2016
Volcanic activity is observed worldwide with a variety of ground and space-based remote sensing instruments, each with advantages and drawbacks. No single system can give a comprehensive description of eruptive activity, and so, a multi-sensor approach ...

Vog: Using Volcanic Eruptions to Estimate the Health Costs of Particulates

open access: yesThe Economic Journal, EarlyView., 2018
The negative consequences of long‐term exposure to particulate pollution are well established but a number of studies find no effect of short‐term exposure on health outcomes. The high correlation of industrial pollutants complicates the estimation of the impact of individual pollutants on health.

Differential response of chlorophyll-a concentrations to explosive volcanism in the western South Pacific

open access: yesFrontiers in Marine Science, 2023
When it is deposited in the ocean, volcanic ash has the potential to release iron and other nutrients into surface water to stimulate ocean productivity. In the western South Pacific Ocean (SPO), one of the most important volcanic ash deposition regions,

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.
