Greasing the fault
Article Abstract:
An isolation-compaction mechanism may explain the high pore pressures produced by slipping faults at high temperatures and pressures. Geophysicists have sought to understand how overpressured fluids could cause California's San Andreas fault to lack the strength of the adjacent rocks as indicated by geophysical measurements. Michael L. Blanpied and colleagues propose that these measurements result from a process involving hydraulic isolation of the fault zone, an increase in pore pressure due to the powdered rock being compacted followed by slip at unexpectedly low pressures.

Creep events preceding small to moderate earthquakes on the San Andreas fault
Article Abstract:
Small to moderate earthquakes are predicted to occur after the creep events or aseismic slips in the San Andreas fault in central California. The prediction is based on a relative study of the archival creep data and the earthquake records of central California. In the San Andreas fault, creep events were followed by earthquakes within five days, for five successive times between Apr to Sep, 1995. However, the creep events and earthquakes lack a direct spatial relationship.

Strength of the San Andreas
Article Abstract:
The San Andreas fault system in California has provided much information on earthquake patterns but knowledge of the physics of such plate-bounding faults remains inadequate. New evidence suggesting that the San Andreas fault is relatively 'strong' may help to provide predictability data about earthquakes on other faults.
