content: I stumbled across this the other day!Electronic Charge Carriers in Igneous Rocks and their Activation through Tectonic ProcessesFriedemann FreundSan Jose State University, Department of Physics/NASA Ames Research CenterAbstract:"Most rocks, in particular igneous rocks of the continental crust are fairly good insulators. Whenevertheir electrical conductivity increases, locally or with depth along the geotherm, the increase is thoughtto be caused by (1) pore water, (2) intergranular carbon films, or (3) incipient partial melting.However, there is mounting evidence that igneous rocks contain an elusive type of electronic chargecarriers, totally overlooked in the past. These charge carriers are defect electrons in the O2– sublattice,O–, also known as positive holes. Normally they lie dormant in form of spin-coupled positive holepairs, PHP, where two O– are linked in a peroxy bond, O––O–. In this paired state they are electricallyinactive and undetectable.Yet, when activated, PHPs release positive hole charge carriers, which arehighly mobile and turn the rocks momentarily into pure p-type semiconductors. Hence, wheneverPHPs are activated, positive holes will appear. They have the potential of affecting not only theelectrical conductivity of rocks but also other properties of geophysical and geochemical interest.My contribution to the EarthScope workshop will center on the role which the elusive PHPs andpositive hole charge carriers may play in large-scale tectonic and magmatic processes in the crust."Download:http://www-scec.usc.edu/news/01news/es_abstracts/Freund.pdfAdded-- VIDEOS- see comments below for caption.. I saw this, a long time ago, during a huge earthquake I was in.I was also in this earthquake..A lady I knew was actually caught on the top deck of the Bay Bridge..Luckily she stopped her car when she saw people driving back towards her waving to stop.....and didn't drive into the huge hole that had opened up, a bus almost fell in..Here is another video from Mexico.. notice the lights in the sky!

content: Cool. At last a workable explanation for earthquake lights. (Glows in the sky, before and during earthquakes.)Possibly also a factor in volcano ash-cloud lightning.There are two obvious typo errors in the text:"From extreme situations encountered prior to large earthquakes we can learn not about non-seismic earthquake precursors. We can also learn, more generally, about ..."===> we can learn not ONLY about non-seismic"When the charge carriers reached the surface they gave rise to positive surface potentials of the order of a few hundred mV. These surface potentials gave rise to very high electric fields across the surface-to-air interface and, hence, to corona discharges.===> "mV" is obviously wrong. KV? MV? Probably KV.Related, though not much there:http://www.thunderbolts.info/tpod/2005/arch05/050302electric-earth.htm

content: Probably "megavolts" -Ive seen earthquake lights. And I wasnt the only person to see them. It was during a huge earthquake that I was in in northern California. The earthquake occurred in the wee hours of the morning and knocked me out of bed. At the time I was living in a quite substantial old house that had a view out towards the ocean. There were bright greenish flashes in the sky to the south west. It was a pretty big earthquake. There was ground liquefaction and all sorts of windows broke, but not as much other damage as you might think there would be because of the nature of the construction in the area. There was very strong sharp ground motion though. More so than any other earthquake Ive been in.***Edit- wow- there are now videos of identical looking lights on YouTube! Check this out! This is what I saw, exactly.*** I've seen all this kind of stuff, actually. Swinging chandeliers and lights too.. this captures what its like. I am moving the videos up to the top, this is cool to see it again- yes I totally remember - it gives me a kind of chill to see it again. It was soooo strange..

content: I've done research into this kind of stuff for a science project. Mostly into piezoelectric theory. They actually have big rotary HV generators on trucks they can use to force certain faults into being more active (I think it was in Japan if I remember right). They also covered earthquake lights on the show Strange Evidence.EDIT: Would it actually be possible to get struck by one of these discharges and die?EDIT2: Probably! One hits close to the camera in this video! That looks like it would hurt if you were standing there! It looks like a big ass horseshoe arc jumping out of the ground! (Hard to see it due to camera saturation though).

content: I am not discounting the possibility of Earthquake Lights, but all the videos look like normal lightning to me.Anecdotal stories suggest animals behave different around earthquakes, but studies show it is just normal behaviour that people flag as different just because they happen to remember it around a significant event. Earthquake lights could be the same thing. It would be necessary to show similar lights do not occur during all the time earthquakes are not occurring, which obviously no one bothers to do.

content: QuoteThat's because it IS a form of lightning. It's ground-ground lightning. The flashes you see in the clouds are reflections.NOTE: Some videos have potentially been debunked as power lines swinging and arcing together, and the one in Japan as a transformer blast. Although if that's the case, it would be hard to tell apart visually since either way it's just electricity. Too bad the one I posted doesn't have sound, as it the closest I've ever seen them go off, it would be easy to tell if it sounded like lightning or lines arcing.

content: The lights I saw were over the ocean! Which is also where the earthquake epicenter was. It was a huge earthquake. It seemed much stronger and more abrupt than the one in San Francisco to me.Given that lightning can be seen and tracked from space its likely that at this point we also have remote sensing data on earthquake lights.That sounds like a good question to put to scientists!Quote from: Cyberdragon on January 12, 2018, 03:44:06 pm
