Transient and steady‐state friction in non‐isobaric conditions

S Barbot - Geochemistry, Geophysics, Geosystems, 2024 - Wiley Online Library

On the interplay between distributed bulk plasticity and local fault slip in evolving fault zone complexity

M Abdelmeguid, MS Mia… - Geophysical Research …, 2024 - Wiley Online Library
We numerically investigate the role of plastic strain accumulation on the mechanical
response of a planar strike‐slip fault. Our models show that fault‐zone strength significantly …

The paucity of supershear earthquakes on large faults governed by rate and state friction

C Liang, JP Ampuero… - Geophysical Research …, 2022 - Wiley Online Library
Supershear earthquakes are rare compared to their subshear counterparts, but the cause for
their paucity remains to be understood. We investigate for the first time the prevalence of …

Stress heterogeneity and the onset of faulting along geometrically irregular faults

D Morad, V Lyakhovsky, YH Hatzor… - Geophysical Research …, 2022 - Wiley Online Library
We present a two‐dimensional analytical solution for the static stress field around a rough
interlocked interface under background stresses and its applications to faulting. The solution …

Slow slip as an indicator of fault stress criticality

V Lambert - Geophysical Research Letters, 2024 - Wiley Online Library
Fault regions inferred to be slowly slipping are interpreted to accommodate much of tectonic
plate motion aseismically and potentially serve as barriers to earthquake rupture. Here, we …
