Linking Stress Drop and Slip Heterogeneity to Assess Source Rupture Directivity for Earthquakes in Central Italy

open access: yesTerra Nova, EarlyView.
ABSTRACT In this study, we examine the relationship between Brune stress drop and fault slip where the stress drop is estimated using the Empirical Green's Function (EGF) method and slip distribution is derived from seismic and geodetic data inversion.

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.

Connecting with tephras: principles, functioning, and applications of tephrochronology in Quaternary science [PDF]

open access: yes, 2013
Tephrochronology is a unique method for linking and dating geological, palaeoecological, palaeoclimatic, or archaeological sequences or events. The method relies firstly on stratigraphy and the law of superposition, which apply in any study that connects

Volcano disaster risk management during crisis: implementation of risk communication in Indonesia

open access: yesJournal of Applied Volcanology, 2023
Volcano disaster risk management during a crisis requires continuous and intensive risk communication with the public. However, to have the desired public response during a crisis, it is necessary to improve the community’s understanding of volcanoes ...

Impact vesiculation – a new trigger for volcanic bubble growth and degassing [PDF]

open access: yes, 2007
We highlight a potentially important trigger for bubble growth and degassing in volcanic bombs. We have successfully triggered bubble growth in previously unvesiculated samples of silicate melt during experiments to simulate volcanic bomb impact, by ...

Fossil trees, tree moulds and tree casts in the Palaeocene Mull Lava Field, NW Scotland: context, formation and implications for lava emplacement [PDF]

open access: yes, 2016
Megafossils and macrofossils of terrestrial plants (trees, leaves, fruiting bodies, etc.) are found in sedimentary and pyroclastic units interbedded with lavas in many ancient lava fields worldwide, attesting to subaerial environments of eruption and the

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 ...
