Scaling of the critical slip distance for seismic faulting with shear strain in fault zones
Article Abstract:
A study of the relationship between the critical slip distance (Dc) and shear strain in a simulated fault gouge is reported. The Dc on an earthquake-generating fault has a key role in determining the rupture nucleation dimension, the amount of premonitory and post-seismic slip and the maximum seismic ground acceleration. The results showed that Dc scales with shear strain in a simulated fault gouge. This suggests that Dc is controlled by the thickness of the zone of localized shear strain. The applications for adjusting discrepancies between field- and laboratory-based estimates of Dc are discussed.

The effect of loading rate on static friction and the rate of fault healing during the earthquake cycle
Article Abstract:
Laboratory measurements show that static friction and healing of faults vary with loading rate and time. These results were applied to seismic faulting and it is demonstrated that post-seismic healing will be retarded for several hundred days following an earthquake. This is in agreement with findings from repeating earthquakes.

Shaking faults loose
Article Abstract:
Research is presented describing the study of seismic waves and the methods by which they travel after an earthquake to produce aftershocks in neighbouring faults.
