Effect of Fluid Viscosity on Earthquake Nucleation [PDF]

Geophysical Research Letters, 2020
AbstractInjection of fluids in geo‐reservoirs can reduce the effective stresses at depth, lubricating the nearby faults, promoting slip and, potentially, earthquakes. High‐viscous fluids are often used during hydraulic fracturing and production phases in geo‐reservoirs.

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 ...

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
