On the puzzling feature of the silence of precursory electromagnetic emissions

K. Eftaxias, S. M. Potirakis, T. Chelidze

The results also imply that the activation of a single earthquake (fault) is a reduced self-affine image of the whole regional seismicity and a magnified self-affine image of the laboratory seismicity.  ...  The search of precursory patterns is mainly based on well documented scaling properties of fault surface topology.  ...  This evidence supports the hypothesis that the detected EM precursor is a subproduct of the Athens fault system nucleation.  ...

Shear stress in fault zones

Barry Kean Atkinson
1982 Nature  
The key evidence of long-term, low shear stress, probably around lO MPa, comes from the absence of a heat flow anomaly around the San Andreas Fault.  ...  Relatively high moments for short fault breaks are only achieved in association with a large volume of relaxation which can be larger than the inclusion.  ...
