Geophysical Research Letters, 2021 We use 3D dynamic rupture simulations to discover a previously un‐described effect of asymmetric topography on the earthquake process. With the Cajon Pass along the San Andreas Fault as an example, we find that asymmetric topography generates an ...

Journal of Geophysical Research: Solid Earth, 2022 Fluid injection stimulates seismicity far from active tectonic regions. However, the details of how fluids modify on‐fault stresses and initiate seismic events remain poorly understood.

Off‐Fault Damage Characterization During and After Experimental Quasi‐Static and Dynamic Rupture in Crustal Rock From Laboratory P Wave Tomography and Microstructures [PDF]
Journal of Geophysical Research: Solid Earth, 2020 Elastic strain energy released during shear failure in rock is partially spent as fracture energy Γ to propagate the rupture further. Γ is dissipated within the rupture tip process zone, and includes energy dissipated as off‐fault damage, Γoff ...

The Dynamics of Elongated Earthquake Ruptures [PDF]
Journal of Geophysical Research: Solid Earth, 2019 AbstractThe largest earthquakes propagate laterally after saturating the fault's seismogenic width and reach large length‐to‐width ratiosL/W. Smaller earthquakes can also develop elongated ruptures due to confinement by heterogeneities of initial stresses or material properties. The energetics of such elongated ruptures is radically different from that

Geochemistry, Geophysics, Geosystems, 2022 Despite decades‐long debate over the mechanics of low‐angle normal faults (LANFs) dipping less than 30°, many questions about their strength, stress, and slip remain unresolved.

Dynamic nucleation as a cascade-up of earthquakes depending on rupture propagation velocity
Earth, Planets and Space, 2023 Earthquake dynamic rupture requires a nucleation process to provide sufficient energy to overcome the fracture energy. Large earthquakes may occur via a cascading rupture process, which includes many triggering processes that cascade from small to large ...

Single-Molecule Rupture Dynamics on Multidimensional Landscapes [PDF]
Physical Review Letters, 2010 We explore emergent effects of multidimensionality of the free energy landscape on single-molecule kinetics under constant force. The proposed minimal model reveals the existence of a spectrum of unusual scenarios for the force-dependent lifetime, all of which are shown to occur on a free energy landscape with a single transition state.

Rupture-dependent breakdown energy in fault models with thermo-hydro-mechanical processes [PDF]
Solid Earth, 2020 Substantial insight into earthquake source processes has resulted from considering frictional ruptures analogous to cohesive-zone shear cracks from fracture mechanics.

Dilatancy-induced fluid pressure drop during dynamic rupture: Direct experimental evidence and consequences for earthquake dynamics [PDF]
Earth and Planetary Science Letters, 2019 Fluid pressure and flow in the crust is a key parameter controlling earthquake physics. Since earthquake slip is linked to spatio-temporal localisation of deformation, it is expected that the localised fluid pressure around the fault plane could ...
