The answers to most of your questions can be found on my Web pages. However, to save you some searching –

A computer program I developed uses information such as the positions of the sun and moon in the sky to match EM Signals with past earthquakes. The closest matches are displayed on the world maps.

Relatively little is known about the EM Signals that I am working with, even by me. I have an unusual way of detecting them that does not provide too much information regarding their nature. And there hasn’t been time to do much research on them.

Some of the signals can be detected by people around the world as "Ear Tones." And they can be easily duplicated in the laboratory.

My best guess is that these signals represent fluctuations in the Earth’s geomagnetic energy field. They range from 0.25 seconds to 30 seconds in length and go from perhaps 4 cycles per second up to 7500 cycles per second. They can apparently be detected anywhere on the planet. Some are strongest near the fault zone associated with them. Some might be generated by the fault zone rock layers. Others appear to involve interactions between fault zones and the Earth's geomagnetic field. The fault zone can act as a temporary “ground” of sorts for the energy in that field among other things.
