Stable Fault Sliding and Earthquake Nucleation

, 1993
The process of earthquake nucleation is studied assuming that faults are rupture surfaces on which sliding is controlled by friction. Earthquakes are assumed to arise through an instability of frictional sliding. Empirical slip laws indicate that, under constant ambient conditions, friction depends on time, slip rate and slip history.

Seismic Evidence for an Earthquake Nucleation Phase

Science, 1995
Near-source observations show that earthquakes initiate with a distinctive seismic nucleation phase that is characterized by a low rate of moment release relative to the rest of the event. This phase was observed for the 30 earthquakes having moment magnitudes 2.6 to 8.1, and the size and duration of this phase scale with the eventual size of the ...

Earthquake nucleation on (aging) rate and state faults [PDF]

Journal of Geophysical Research, 2005
We obtain quasi-static, two-dimensional solutions for earthquake nucleation on faults obeying Dieterich's “aging” version of the rate and state friction equations.

Testing a model of earthquake nucleation

Bulletin of the Seismological Society of America, 1995
Abstract Some laboratory models of slip find that a critical amount (or velocity) of slow slip is required over a nucleation patch before dynamic failure begins. Typically, such patch sizes, when extrapolated to earthquakes, have been thought to be very small and the precursory slip undetectable.

A source model for earthquakes near the nucleation dimension

Bulletin of the Seismological Society of America, 2022
Earthquake self-similarity is a controversial topic, both observationally and theoretically. Theory predicts a finite nucleation dimension, implying a break of self-similarity below a certain magnitude. While observations of non self-similar earthquake behavior have been reported, their interpretation is challenging due to trade-offs between source and
