A source model for earthquakes near the nucleation dimension
Bulletin of the Seismological Society of America, 2022Earthquake 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

Earthquake nucleation by transient deformations caused by the M = 7.9 Denali, Alaska, earthquake
Nature, 2004The permanent and dynamic (transient) stress changes inferred to trigger earthquakes are usually orders of magnitude smaller than the stresses relaxed by the earthquakes themselves, implying that triggering occurs on critically stressed faults. Triggered seismicity rate increases may therefore be most likely to occur in areas where loading rates are ...

Stable Fault Sliding and Earthquake Nucleation
1993The 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.

Friction law for earthquake nucleation: size doesn’t matter
2022A central question in modeling induced and natural earthquake nucleation is whether fault frictional properties measured in the laboratory are applicable to nature. A laboratory fault is generally just a few centimeters in length-width scale, while natural faults can be hundreds of meters to kilometers in extent.

Nucleation of earthquakes and its implication to precursors
Acta Seismologica Sinica, 2000The recent argument about nucleation phase of earthquakes reminds us to completely study the concept of earthquake nucleation. The original meaning of nucleation includes concentration, nucleation and initiation of the eruptive processes. Thus, it is needed to discuss how to exactly translate the word “nucleation” into Chinese in different fields.

Earthquake source nucleation as self organization process
Tectonophysics, 2007Abstract The theory of an earthquake source nucleation is discussed. Based on the assumption that self organization of damage process takes place in the zone of an earthquake source nucleation the theory incorporates the damage rheology framework of Lyakhovsky et al. and the approach of phenomenology theory of second-order phase transition.

Strong asperities nucleate earthquakes on laboratory faults
GeologyAbstract Abundant heterogeneity has been documented on faults in nature across a wide range of length scales, including structural, mineralogical, and roughness variations. The role of complex heterogeneity on fault mechanics and frictional stability is not well established, and experiments investigating heterogeneity have typically ...

Scaling and Nucleation in Models of Earthquake Faults
Physical Review Letters, 1997We present an analysis of a slider block model of an earthquake fault which indicates the presence of metastable states ending in spinodals. We identify four parameters whose values determine the size and statistical distribution of the {open_quotes}earthquake{close_quotes} events.
