Forecasting catastrophic rupture in brittle rocks using precursory AE time series

JZ Zhang, XP Zhou - Journal of Geophysical Research: Solid …, 2020 - Wiley Online Library
An evidently precursory acoustic emission (AE) time series, characterized by a time‐
reversed Omori law, is registered prior to the unconfined catastrophic rupture of brittle …

Strain localization in magmas

Y Lavallée, JE Kendrick - Reviews in Mineralogy and …, 2022 - pubs.geoscienceworld.org
One of the most intriguing and (from the point of view of modeling) poorly understood
aspects of geomaterial mechanics is strain localization. Strain localization is a common …

Characterization of volcanic regimes and identification of significant transitions using geophysical data: a review

R Carniel - Bulletin of Volcanology, 2014 - Springer
A volcano can be considered as a dynamical system, and each time series recorded at a
volcano can be interpreted as one of its observables. It is therefore theoretically possible to …

Heterogeneity: The key to failure forecasting

J Vasseur, FB Wadsworth, Y Lavallée, AF Bell… - Scientific reports, 2015 - nature.com
Elastic waves are generated when brittle materials are subjected to increasing strain. Their
number and energy increase non-linearly, ending in a system-sized catastrophic failure …

Catastrophic failure: how and when? Insights from 4‐D in situ x‐ray microtomography

A Cartwright‐Taylor, IG Main, IB Butler… - Journal of …, 2020 - Wiley Online Library
Catastrophic failure of brittle rocks is important in managing risk associated with system‐
sized material failure. Such failure is caused by nucleation, growth, and coalescence of …

Forecast of time-of-instability in rocks under complex stress conditions using spatial precursory AE response rate

Y Niu, XP Zhou - International Journal of Rock Mechanics and Mining …, 2021 - Elsevier
The precursory response rate with the relationship of the time-reversed Omori law can
characterize the damage acceleration behavior in the approach to the local instability of …

Stress transmission and failure in disordered porous media

H Laubie, F Radjai, R Pellenq, FJ Ulm - Physical review letters, 2017 - APS
By means of extensive lattice-element simulations, we investigate stress transmission and its
relation with failure properties in increasingly disordered porous systems. We observe a non …

Dynamics of microscale precursors during brittle compressive failure in Carrara marble

N Kandula, B Cordonnier, E Boller… - Journal of …, 2019 - Wiley Online Library
Microscale heterogeneities influence failure mechanisms in the crust. To track the
microstructural changes in rock samples when loaded until failure, we employed a novel …

Prospective forecast of sliding instability time using a precursory AE time series

XP Zhou, CQ Li - Tribology International, 2022 - Elsevier
Forecasting the timing of an earthquake is both fascinating and challenging. In this paper,
four efforts were made to prospectively forecast the laboratory earthquake timing of granite …

Using volcanic tremor for eruption forecasting at White Island volcano (Whakaari), New Zealand

L Chardot, AD Jolly, BM Kennedy, N Fournier… - Journal of Volcanology …, 2015 - Elsevier
Eruption forecasting is a challenging task because of the inherent complexity of volcanic
systems. Despite remarkable efforts to develop complex models in order to explain volcanic …
