Earthquake nucleation on rough faults [PDF]
Geology, 2017 Earthquake nucleation is currently explained using rate and state stability analysis, which successfully models the behavior of laboratory simulated faults with constant thickness gouge layers.

Earthquake nucleation in weak subducted carbonates [PDF]
Nature Geoscience, 2016 Ocean-floor carbonate- and clay-rich sediments form major inputs to subduction zones, especially at low-latitude convergent plate margins. Therefore, knowledge of their frictional behaviour is fundamental for understanding plate-boundary earthquakes.

The Effects of Fault Roughness on the Earthquake Nucleation Process [PDF]
Journal of Geophysical Research: Solid Earth, 2018 AbstractWe study numerically the effects of fault roughness on the nucleation process during earthquake sequences. The faults are governed by a rate and state friction law. The roughness introduces local barriers that complicate the nucleation process and result in asymmetric expansion of the rupture, nonmonotonic increase in the slip rates on the ...

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 ...

Effect of Fluid Viscosity on Earthquake Nucleation [PDF]
Geophysical Research Letters, 2020 Injection of fluids in geo‐reservoirs can reduce the effective stresses at depth, lubricating the nearby faults, promoting slip and, potentially, earthquakes.

Frictional healing and induced earthquakes on conventionally stable faults [PDF]
Nature CommunicationsConventional studies suggest that faults in the shallow subsurface resist earthquake nucleation, because their frictional strength increases as slip accelerates (i.e., velocity-strengthening friction).

Earthquake simulations with time-dependent nucleation and long-range interactions [PDF]
Nonlinear Processes in Geophysics, 1995 A model for rapid simulation of earthquake sequences is introduced which incorporates long-range elastic interactions among fault elements and time-dependent earthquake nucleation inferred from experimentally derived rate- and state-dependent fault ...

Earthquake Nucleation and Slip Behavior Altered by Stochastic Normal Stress Heterogeneity
Journal of Geophysical Research - Solid EarthIn recent laboratory experiments, varying nucleation locations of accelerating slip with changing nucleation lengths were observed. Spatial variations in effective normal stress, due to the controlling influence on fault strength and fracture energy ...

Foreshocks and Mainshock Nucleation of the 1999 Mw 7.1 Hector Mine, California, Earthquake
Journal of Geophysical Research: Solid Earth, 2019 Foreshocks provide valuable information on the nucleation process of an upcoming large earthquake. We applied high‐resolution similar‐waveform techniques for earthquake detection, location, and source parameter estimation to understand the space‐time ...
