Fault strength and rupture process controlled by fault surface topography

S Xu, E Fukuyama, F Yamashita, H Kawakata… - Nature …, 2023 - nature.com
Faults are rarely completely smooth, with topographic undulations coming from the
distribution of asperities along the fault surface. Understanding the effects of fault surface …

Preparatory slip in laboratory faults: Effects of roughness and load point velocity

S Guérin‐Marthe, G Kwiatek, L Wang… - Journal of …, 2023 - Wiley Online Library
Aseismic slip may occur during a long preparatory phase preceding earthquakes, and what
controls it remains poorly understood. In this study, we explored the role of load point …

A synthesis of fracture, friction and damage processes in earthquake rupture zones

Y Ben-Zion, G Dresen - Pure and Applied Geophysics, 2022 - Springer
We review properties and processes of earthquake rupture zones based on field studies,
laboratory observations, theoretical models and simulations, with the goal of assessing the …

Back‐propagating rupture: Nature, excitation, and implications

X Ding, S Xu, E Fukuyama… - Journal of Geophysical …, 2024 - Wiley Online Library
Recent observations show that certain rupture phase can propagate backward relative to the
earlier one during a single earthquake event. Such back‐propagating rupture (BPR) was not …

The sharp turn: Backward rupture branching during the 2023 Mw 7.8 Kahramanmaraş (Türkiye) earthquake

X Ding, S Xu, Y Xie, M Van den Ende, J Premus… - Seismica, 2023 - hal.science
Multiple lines of evidence indicate that the 2023 Mw 7.8 Kahramanmaraş (Türkiye)
earthquake started on a splay fault, then branched bilaterally onto the nearby East Anatolian …

Frictional behavior and micro-damage characteristics of rough granite fractures

F Meng, LNY Wong, T Guo - Tectonophysics, 2022 - Elsevier
Natural faults or discontinuities in general are usually rough at different scales, and the
roughness of fault surfaces plays a dominant role in determining the mode of sliding (stable …

The 2021 Mw7. 0 and Mw6. 7 Miyagi‐oki earthquakes nucleated in a deep seismic/aseismic transition zone: possible effects of transient instability due to the 2011 …

Abstract In March and May 2021, Mw7. 0 and Mw6. 7, respectively, deep interplate
earthquakes occurred off Miyagi, Japan, near the downdip edge of the rupture area of the …

The sharp turn: backward rupture branching during the 2023 Mw 7.8 Turkey earthquake

X Ding, S Xu, Y Xie, M Ende, J Premus… - arXiv preprint arXiv …, 2023 - arxiv.org
Multiple lines of evidence indicate that the 2023 Mw 7.8 Turkey earthquake started on a
splay fault, then branched bilaterally onto the nearby East Anatolian Fault (EAF). This …

Laboratory earthquake ruptures contained by velocity strengthening fault patches

JY Song, GC McLaskey - Journal of Geophysical Research …, 2024 - Wiley Online Library
Many natural faults are believed to consist of velocity weakening (VW) patches surrounded
by velocity strengthening (VS) sections. Numerical studies routinely employ this framework …

Evolution of Shear Rupture Along a Prescribed Interface Using the Discontinuous Deformation Analysis Method

Q Wang, Y Zhang, L Wang, P Yu… - Rock Mechanics and …, 2024 - Springer
Laboratory experiments suggest that the evolution of in-plane shear rupture along an
interface separating two elastic blocks typically shows a transition from slow to fast slip. In …
