Relative Afterslip Moment Does Not Correlate With Aftershock Productivity: Implications for the Relationship Between Afterslip and Aftershocks

Geophysical Research Letters, 2022
AbstractAseismic afterslip has been proposed to drive aftershock sequences. Both afterslip moment and aftershock number broadly increase with mainshock size, but can vary beyond this scaling. We examine whether relative afterslip moment (afterslip moment/mainshock moment) correlates with several key aftershock sequence characteristics, including ...

Afterslip (and only afterslip) following the 2004 Parkfield, California, earthquake [PDF]

Geophysical Research Letters, 2007
An analysis of the first two years of postseismic surface deformations from GPS reveals that afterslip is the only mechanism significantly contributing to postseismic deformation following the 2004 M6 Parkfield, California earthquake. Finite element modeling shows this event to have been too small to significantly stress the lower crust and upper ...

Afterslip and aftershocks in the rate‐and‐state friction law [PDF]

Journal of Geophysical Research, 2009
We study how a stress perturbation generated by a main shock affects a fault obeying the rate‐state friction law using a simple slider block system. Depending on the model parameters and on the initial stress, the fault exhibits aftershocks, slow earthquakes, or decaying afterslip. We found several regimes with slip rate decaying as a power law of time,

On the mechanics of earthquake afterslip

Journal of Geophysical Research: Solid Earth, 1991
We propose a model for earthquake afterslip based on rate and state variable friction laws. In the model, afterslip is attributed to the interaction of a velocity‐weakening region at depth (within which earthquakes nucleate) with an upper region of velocity‐strengthening frictional behavior.

Space‐time distribution of afterslip following the 2009 L'Aquila earthquake

Journal of Geophysical Research, 2012
The inversion of multitemporal DInSAR and GPS measurements unravels the coseismic and postseismic (afterslip) slip distributions associated with the 2009 MW 6.3 L'Aquila earthquake and provides insights into the rheological properties and long‐term behavior of the responsible structure, the Paganica fault. Well‐resolved patches of high postseismic slip
