Southern California Seismic Alert: San Jacinto Fault Zone

The Loma Linda Fault is an Active Splay of the San Jacinto Fault Zone, which has been obscured for many years by urban expansion & land development.

Note: The Anza Seismic Gap is a locked segment along the Southern San Jacinto Fault Zone from Anza and Southeast to Coyote Mountain. Micro quake activity 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.

Graphic:(AE)Unclamping Level Chart 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"

- Frank Condon
Graphic:(Map)Tectonic Plates Caption: Map of Global Tectonic Plates and Volcanoes

My philosophy, quite simply stated is:

" The Plate Boundary including the western edge of the ECSZ is the
interface for the transmission of Infrasonic, or AE. 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."
