  within the gap is mainly constrained to two high stress regions concentrated at
  both ends of the asperity, and only at a depth of 15 km in the seismogenic zone,
  which is right above the upper limit of aseismic slip.

Caption:The inferred Mean Average Unclamping Incident Level Observed from
the Pacific & North American Plate Boundary in Southern California.
Major Global Earthquakes have been Preceded by abrupt increases in the
Unclamping Incident Level, as observed during both   December 2004, and   October 2005.

The Pacific Plate is inferred to have transmitted the changes observed here
from a large increase in lithospheric stress along the Sunda Trench, and the
Eurasian Plate. The inference was first made after the M9.2 Great Sumatra
Earthquake, which was preceded by an abrupt increase in the local Unclamping
Incident Level. Since then, I've experimentally utilized the Unclamping Incident
Level as a means for monitoring global tectonic stress levels, with quite
excellent results


Caption: Map of Global Tectonic Plates and Volcanoes

My philosophy is quite simply:
"The Plate Boundary including the western edge of the (ECSZ)
Eastern California Shear Zone is the interface for the transmission of
Infrasonic, or (AE) Acoustic Emissions. Secondary faults are the handshake
lines, which handle the nucleation of the stress..The data lines are the
harmonics, which indicate the severity and the approximate lattitude of the
location by having a different amplitude and frequency for each of the specific
harmonics in the infrasound spectrum. I monitor and record these
frequencies, and analyze the results, which allows me to publish a specific
forecast of the current regional lithospheric stress level. It's not magic, just
good old fashioned hard work while conducting an analysis. I believe
these infrasonic signals are the same ones, which enable many pets,
wild animals, and humans to sense an increase in the level of
stress before an earthquake happens. Also, I utilize the Spring Tides
Lunar Phases and Solar Activity level in my forecasts."
