An earthquake mechanism based on rapid sealing of faults
Article Abstract:
Laboratory experiments indicate that the overpressuring of fluids in geological faults can bring on the slippage that results in earthquakes. These overpressured fluids could diminish the shear stress needed to make the faults slide through a two-step process: sealing and compaction. Sealing blocks the movement of fluids from the fault zone to the adjacent rock and compaction of the fault rock allows slippage by increasing pore pressure in the sealed fault.

No need to stick to the point
Article Abstract:
The results of earthquake nucleation studies using simulated fault zones comprised of two sliding rock surfaces separated by a layer of crushed rock, or fault gouge, are presented. The results showed that the characteristic displacement is directly related to the width of shear-localization bands that develop within the gouge layer. This could represent a breakthrough in the search for physical instability paramaters needed for earthquake prediction.

The dating of shallow faults in the Earth's crust
Article Abstract:
Research describing the dating of near surface fault activity in the Earth's crust is presented. In particular the characterization of clay populations in fault gouge is investigated.
