Volcanology of Ischia (Italy)

open access: yesJournal of Maps, 2018
A volcanological map of the active Ischia volcanic field that includes Vivara Island is presented. The volcanological map is at the 1:10,000 scale and is based on 1:5000 field mapping, geological CAR.G data, and new volcanological studies. Geological data

Squeezing out plastic lava blocks on Young Shiveluch volcano (Kamchatka) in 2020–2021

open access: yesВестник Камчатской региональной ассоциации "Учебно-научный центр". Серия: Науки о Земле, 2021
Volcano Young Sheveluch is one of the most active volcanoes in Kamchatka. Since August 1980 to the present time, an extrusive dome has been growing in the crater of the volcano. Plastic lavas in the form of large ribbons were noted on the dome already in

Efficacy of Assessing Magmatic Storage Depth Using Natural Samples, Experiments and Thermodynamic Models: A Case Study From Valles Caldera, NM (USA)

open access: yesGeochemistry, Geophysics, Geosystems
Estimates of magmatic storage are typically made using mineral assemblages in natural samples, experiments and thermodynamic models (e.g., MELTS), where each method has limitations.

Estimation and uncertainty quantification of magma interaction times using statistical emulation

open access: yesVolcanica
The evolution of volcanic plumbing systems, which controls the style and size of eruptions, is largely determined by processes at depths that are not observable.

DensityX: A program for calculating the densities of magmatic liquids up to 1,627 °C and 30 kbar

open access: yesVolcanica, 2019
Here we present a standalone program, DensityX, to calculate the densities of hydrous silicate melts (1,000s of samples in a single model run) given pressures, temperatures, and major oxide compositions in wt% in the 10-component system SiO2-TiO2-Al2O3 ...

Role of mechanical erosion in controlling the effusion rate of basaltic eruptions

open access: yesGeophysical Research Letters, 2016
In many basaltic eruptions, observations show that the effusion rate of magma has a typical dependence on time: the effusion rate curves show first a period of increasing and later a decreasing phase by a maximum value. We present a model to explain this

Introducing Geoscience Students to Numerical Modeling of Volcanic Hazards: The example of Tephra2 on VHub.org

open access: yesNumeracy, 2012
The Tephra2 numerical model for tephra fallout from explosive volcanic eruptions is specifically designed to enable students to probe ideas in model literacy, including code validation and verification, the role of simplifying assumptions, and the ...
