Investigations and new insights on earthquake mechanics from fault slip experiments

L Dong, Q Luo - Earth-Science Reviews, 2022 - Elsevier
Earthquakes occur mainly on active faults. Fault slip is closely related to seismicity and is
thus widely discussed in Geosciences, Seismology, and Engineering. Slip experiment is a …

Intermittent lab earthquakes in dynamically weakening fault gouge

V Rubino, N Lapusta, AJ Rosakis - Nature, 2022 - nature.com
Large and destructive earthquakes on mature faults in Earth's crust occur as slip in a layer of
a fine granular material—fault gouge—produced by comminution during sliding,. A range of …

Stress perturbation from aseismic slip drives the seismic front during fluid injection in a permeable fault

N Wynants‐Morel, F Cappa… - Journal of …, 2020 - Wiley Online Library
Fluid pressure changes affect fault stability and can promote the initiation of earthquakes
and aseismic slip. However, the relationship between seismic and aseismic fault slip during …

How frictional slip evolves

S Shi, M Wang, Y Poles, J Fineberg - Nature Communications, 2023 - nature.com
Earthquake-like ruptures break the contacts that form the frictional interface separating
contacting bodies and mediate the onset of frictional motion (stick-slip). The slip (motion) of …

Laboratory earthquakes decipher control and stability of rupture speeds

P Dong, K Xia, Y Xu, D Elsworth, JP Ampuero - Nature communications, 2023 - nature.com
Earthquakes are destructive natural hazards with damage capacity dictated by rupture
speeds. Traditional dynamic rupture models predict that earthquake ruptures gradually …

Dynamic rupture initiation and propagation in a fluid-injection laboratory setup with diagnostics across multiple temporal scales

M Gori, V Rubino, AJ Rosakis… - Proceedings of the …, 2021 - National Acad Sciences
Fluids are known to trigger a broad range of slip events, from slow, creeping transients to
dynamic earthquake ruptures. Yet, the detailed mechanics underlying these processes and …

The emergence of crack-like behavior of frictional rupture: Edge singularity and energy balance

F Barras, M Aldam, T Roch, EA Brener… - Earth and Planetary …, 2020 - Elsevier
The failure of frictional interfaces—the process of frictional rupture—is widely assumed to
feature crack-like properties, with far-reaching implications for various disciplines, ranging …

Modeling connected granular media: Particle bonding within the level set discrete element method

JM Harmon, K Karapiperis, L Li, S Moreland… - Computer Methods in …, 2021 - Elsevier
