"STRANGE ATTRACTOR LIKE" ELECTRIC EARTHQUAKE PRECURSORS

INVERSION EXAMPLE-1

In the page of the "synthetic data" it was demonstrated that a circle is generated when the EQ monochromatic signals. recorded by two monitoring sites are processed by the "strange attractor" methodology. So what is the use of such circles? Just remember what is called "strange attractor" in the earthquake prediction topic. Each point of a circle is the intersection of the azimuthal directions of the earth's electric field recorded by the two monitoring sites. Therefore, a specific point of such a circle is the epicenter of the EQ-1 which generates the recorded signals. The seismological target is to determine the epicenter of the EQ-1 which creates such a "strange attractor" electric EQ precursor.

The specific problem was solved as follows:

A hypothetical monitoring array was adopted, consisted of three (3) monitoring sites M1, M2, M3 and a hypothetical random EQ, all of known X, Y coordinates. Next, the theoretical circles were determined in pairs M1-M2, M1-M3, M2-M3. At the next step the EQ-1  X=45, Y=75  coordinates were ignored and an inversion process was applied on all circles by using a random pair of EQ X=-15, Y=-10 coordinate values as initial guess. The results are presented in live form graphs for random EQ location and as total array, using joint inversion methodology.

Each graph consist of two parts. The left is the main live presentation, controlled by the buttons below it and the right one which presents all the parameters of the process and how these change along it.
