Afterslip and aftershocks in the rate-and-state friction law
Agnes Helmstetter, Bruce E. Shaw
We study how a stress perturbation generated by a mainshock affects a population of faults obeying a rate-state friction law. Depending on the model parameters and on the initial s…

Relation between stress heterogeneity and aftershock rate in the rate-and-state model
Agnes Helmstetter, Bruce E. Shaw
We estimate the rate of aftershocks triggered by a heterogeneous stress change, using the rate-and-state model of Dieterich [1994].We show that an exponential stress distribution P…
