Hi Dave, You asked,
“I wonder how his device would be able to keep things like vacuum cleaners and other electric motors from bombing it out.” I don’t think my friend owns a vacuum cleaner! LoL J But to answer your question more directly, the preamp and filtering was designed for *sub-Hz* response… so one could see the spectrum *below* 1Hz, although, I don’t remember that region as being very active. The signal analyzer spec goes down to 30 milli-Hz (0.030Hz). I do remember the very prominent peak at the Schumann resonance (think it was around 6.7-7.3Hz), and of course another very strong peak at 60Hz from the AC grid. It’s been a long time, but I do remember most geomag activity occurred between 2Hz and 20Hz. Most man-made stuff manifests well above several 10s of Hz. When I was there he usually restricted the frequency domain from sub-Hz to 10Hz so as to exclude most man-made sources from the f-spectrum. In addition, the signal analyzer had the ability to display BOTH time domain and frequency domain in separate display ‘windows’. Artificial (i.e., from man-made sources) magnetic effects were easily distinguished from geomag by the behavior of the *time-domain* trace. The t-domain traces from man-made sources were usually quite regular-looking, and geomag just the opposite; very irregular looking and usually a kind of ‘stepped’ behavior; definitely not smoothly analog-like vertical changes. If a geomag ‘event’ was happening at the moment a car drove by, or if he turned on some electric motor, the t-domain trace for the geomag event would get clobbered by the man-made device’s effect on the local mag field. He also oriented the antenna a specific way, but can’t remember if it was parallel to or perpendicular to the local geomag field… Prior to an EQ, there are large areas (tens of square miles or more) of rock which are under tremendous stress, and rock begins to rupture until eventually a very large segment ruptures and you have a major EQ. The hypothesis is that the rupturing is akin to striking a bell, and its subsequent ringing; the rock rupture (strike) causes a ‘ringing’ in the local geomag-field of a few Hz; the ELF ringing of the geomag field propagates outward hundreds, and in the case of 6+ magnitude EQs, even thousands of miles. -Mark From: David Roberson [mailto:[email protected]] Sent: Monday, January 09, 2012 12:24 PM To: [email protected] Subject: Re: [Vo]:Stress-induced negative coefficient of temperature? That is a very interesting story Mark. I wonder how his device would be able to keep things like vacuum cleaners and other electric motors from bombing it out. Did he happen to mention anything about the frequency response of the device? I can imagine that it has a very low cutoff frequency, maybe a couple of hertz.

A little off topic, but perhaps interesting for some rookies in the Collective… For some first-hand experience with how rock fracturing affects it’s magnetic properties, and how that manifests in anomalous geomagnetic activity (for EQ prediction), see this post: <http://www.mail-archive.com/[email protected]/msg47319.html> http://www.mail-archive.com/[email protected]/msg47319.html -Mark From: James Bowery [ <mailto:[email protected]?> mailto:[email protected]] Sent: Monday, January 09, 2012 5:43 AM To: vortex-l Subject: [Vo]:Stress-induced negative coefficient of temperature? Something that occurs to me about the emergence of a negative coefficient of temperature at high loading of hydrogen in metallic lattices is that it may be related to the stress imposed by that loading. If stress reaches a point where charge carriers to emerge, then increasing the temperature may enhance the emergence of those carriers. The emergence of charge carriers with stress is theorized to occur in igneous rock: Stress-Induced Changes in the Electrical Conductivity of Igneous Rocks and the Generation of Ground Currents Author:Friedemann T. Freund, Akihiro Takeuchi, Bobby W. S. Lau, Rachel Post, John Keefner, Joshua Mellon, and Akthem Al-Manaseer Abstract If we can ever hope to understand the non-seismic signals that the Earth sends out before major earthquakes, we need to understand the physics of rocks under increased levels of stress. In particular we need to understand the generation of electrical currents in the ground. We have begun to study how electrical conductivity of igneous rocks changes under stress and what types of charge carriers are involved. We show that quartz-rich granite and quartz-free anorthosite both generate electronic charge carriers when subjected to stress. The charge carriers are positive holes (p-holes), i.e., defect electrons on the oxygen anion sublattice. They spread out of the stressed rock volume, the “source volume”, into the surrounding unstressed rocks. Time-varying ground currents are required to generate pre-earthquake local magnetic field anomalies and low-frequency electromagnetic emissions. We posit that stress-induced activation of p-hole charge carriers and their outflow from the source volume is the basic process by which ground currents can be generated in the Earth’s crust. We propose that the arrival of p-holes at the Earth’s surface leads to changes in the ground potential that may induce ionospheric perturbations. We further propose that the build-up of high electric fields at the ground surface can ionize the air, hence cause ion emission and corona discharges. When p-holes recombine at the ground surface, they are expected to form vibrationally highly excited O-O bonds. The de-excitation of these O-O bonds will lead to stimulated mid-IR emission, which may explain the reported pre-earthquake “thermal anomalies” identified in satellite images.
