Earthquake nucleation in intact or healed rocks [PDF]
Journal of Geophysical Research: Solid Earth, 2015 Earthquakes are generated because faults lose strength with increasing slip and slip rate. Among the simplest representations of slip‐dependent strength is the linear slip‐weakening model, characterized by a linear drop to a residual friction.

An electrochemical hypothesis of earthquakes exploring a theoretical link between radiated seismic energy and Pourbaix potential [PDF]
Scientific ReportsEarthquakes are measured using well-defined seismic parameters such as seismic moment ( $$M_o$$ ), moment magnitude ( $$M_w$$ ), and released elastic energy (E).

Fluid-driven slow slip and earthquake nucleation on a slip-weakening circular fault [PDF]
Journal of the mechanics and physics of solids, 2023 We investigate the propagation of fluid-driven fault slip on a slip-weakening frictional interface separating two identical half-spaces of a three-dimensional elastic solid.

Nucleation Mechanism and Rupture Dynamics of Laboratory Earthquakes at Different Loading Rates
Applied Sciences, 2023 The loading rate of tectonic stress is not constant during long-term geotectonic activity and significantly affects the earthquake nucleation and fault rupture process. However, the mechanism underlying the loading rate effect is still unclear.

Fault surface morphology as an indicator for earthquake nucleation potential
Geology, 2022 Laboratory measurements can determine the potential for geologic materials to generate unstable (seismic) slip, but a direct relation between sliding behavior in the laboratory and physical characteristics observable in the field is lacking, especially ...

Temporal variation of shear-wave splitting parameters before and after the 2008 Movri Mountain earthquake in northwest Peloponnese (Greece) [PDF]
, 2013 On June 8, 2008, at 12:25 GMT, a Mw 6.4 earthquake, the Movri Mountain earthquake, occurred in the area of northwest Peloponnese, western Greece. The epicenter was located in the municipality of Movri, 35 km southwest of Patras. For this study, a crustal
