TL;DR: Lateral dyke growth with segment barrier breaking by pressure build-up in the dyke distal end explains how focused upwelling of magma under central volcanoes is effectively redistributed over long distances to create new upper crust at divergent plate boundaries.
Journal ArticleDOI
Long-period seismicity in the shallow volcanic edifice formed from slow-rupture earthquakes
Christopher J. Bean,Louis De Barros,Louis De Barros,Ivan Lokmer,Jean-Philippe Métaxian,Gareth O’ Brien,Shane Murphy +6 more
TL;DR: In this article, an analysis and modelling of long-period seismicity at volcanoes in Italy, Costa Rica and Peru shows that it could instead be caused by slow rupture along faults in the upper volcanic edifice.
Journal ArticleDOI
The broad-band fractal nature of heterogeneity in the upper crust from petrophysical logs
TL;DR: In this paper, the authors used a range of different techniques, including autocorrelation, semi-variogram, rescaled range and power spectra, to estimate the fractal dimension.
Journal ArticleDOI
Influence of near-surface volcanic structure on long-period seismic signals and on moment tensor inversions : Simulated examples from Mount Etna
TL;DR: In this article, the influence of near-surface volcanic structure on LP signals and on moment tensor inversions was investigated using 3-D full wavefield simulations and 2-D sensitivity kernels in a digital elevation model of Mount Etna.
Journal ArticleDOI
Numerical simulation of seismic waves using a discrete particle scheme
Aoife Toomey,Christopher J. Bean +1 more
TL;DR: In this paper, a particle-based model for the simulation of wave propagation is presented, which is based on solid-state physics principles and considers a piece of rock to be a Hookean material composed of discrete particles representing fundamental intact rock units.
