* Someone on a nearby thread mentioned this very interesting article, called "An Integrated Alternative Conceptual Framework to Heat Engine Earth, Plate Tectonics, and Elastic Rebound", which is located on this webpage: http://www.scientificexploration.org/jo ... tassos.pdf. It goes into great detail and seems to explain a lot.
* It says the velocity of S and P waves etc suggests that Earth's deep interior is cool, not hot.
* Here are brief statements about the electrical nature of earthquakes from the article.It says "the source of thermal energy of Earth’s interior is the radiant heat produced by ... released resonating electrons inside the 10^6 to 10^5 m microfractures, which enable electrons to vibrate harmonically at thermal frequencies".
* I don't imagine the article speculates about the Earth getting charged from the solar wind etc, but it does mention also the electrical effects of impacts. I've only skimmed it so far, so there may be yet more gold in that goldmine.- The Electron Resonance Stimulated by Excess Mass Electrons—ERSEME—process and the dual role of microcracks, (a) as wave harmonically resonant cavities, where radiant heat and other precursory phenomena are produced; (b) as a network of many effective capacitors, connected in parallel electrically, the implosive gravitational collapse of which produces all earthquake shock types, whether deep-focus, shallow focus, tectonic or volcanic.
- The catastrophic cavity network collapse which follows discharge is similar to dielectric breakdown and failure of a capacitor. The drop of geoelectric potential and the increased conductivity at the earthquake preparatory stage, that observably culminates co-seismically..., corroborates the logic presented here, that an earthquake itself is fundamentally an electromagnetic phenomenon.
