Re: Electric Earthquakes

What are the chances of a larger earthquake occuring? We just got a 5.8 earthquake over here about a half hour ago. What would you say are the chances of a much larger one happening this week?

Re: Electric Earthquakes

There is a Yahoo group that detect ELF / ULF waves and find correlations with Earthquakes. The waves of frequency about 2 Hz are the ones to watch for. These guys have lots of files and graphs of frequency plots etc in the group and have been at this a long time.
See http://groups.yahoo.com/group/ulfelf/

Re: Electric Earthquakes

CAN THE IONOSPHERIC PLASMA TURBULENCE BE A PRECURSOR OF THE EARTHQUAKE? RESULTS OF DEMETER MEASUREMENTS

The disturbances of the electromagnetic field around areas of the earthquakes as preseismic events can occur few hours or even few days before main shock. The payload of the DEMETER French microsatellite allows to measure waves and also some important plasma parameters (ion composition, electron density and temperature, energetic particles) with high temporal resolution in the ionosphere over the seismic regions. In the present work analysis of the low frequency fluctuations of the electric fields for the selected strong earthquakes will be given. Special attention will be given to study of the characteristics of the spectra of these variations and search of the nonlinear effects. This analysis is possible in the time interval when the waveform has been transmitted. The mechanism of the energy transmission from the earthquake to the ionosphere is not clear, but we can discuss the behavior of the ionospheric plasma and search of the instabilities which could be a source of the electromagnetic field variations. Some attempt of this discussion will be given in the presentation. The brief discussion of the characteristics of the spectra and multispectra is given in this paper

CONCLUSIONS
In the present paper the electromagnetic effects observed by DEMETER satellite prior to the strong earthquakes in
Japan, Taiwan, Eastern Sichuan and Italy (Aquila) have been shortly discussed. The analysis of the wave form in ELF
frequency range with Fourier, wavelet and bispectral methods has shown the presence of the strong emissions in this frequency range in the ionosphere 6 till 2 days or even 1 day before the earthquake. Moreover the obtained results for Sichuan earthquake correlate very well in time and position with observations of the thermal anomalies reported by in [19]. The discussed results were obtained during very quiet time and therefore no ionospheric and magnetospheric sources of perturbations were expected. However these turbulence behaviors are not specifically related to the occurrence of earthquakes and can be met in other regions of the ionosphere particularly at equatorial and high latitudes [20]. But the closest occurrence in space and in time suggests that the observed effects at mid-latitudes are related to a perturbation of the ionosphere which could be associated with the preparation of the discussed earthquakes. Now we expect the answer for the question given in the title of present paper. But the answer is not resolving. Presented examples show the presence of the variation of the electric field in ELF range indicating the features of the turbulence. We can say that effect is present few days prior to the earthquake, but the very similar variations can be observed in the ionosphere not associated with the earthquake. In the Sichuan case some additional information from metrological satellite supported our suggestion, but all presented cases were chosen for very quite geomagnetic situation. In the case of disturbed magnetosphere it will be very difficult to distinguish the disturbances originated from the earthquake from the other. We can conclude that only complex measurements, not only plasma, can give in the future positive method of forecasting of the earthquakes. Nevertheless electromagnetic effects associated with the plasma turbulence in the ionosphere can be one of significant indicators. What new can be obtained from SWARM satellites in this subject? The orbit of DEMETER satellite with period about 90 minutes cannot allow to see the time evolution of the processes near the epicenter. The visit of the same place is only after about 24 hours. The fleet of 3 satellites with some separation of their orbit allows to study the characteristic changes of the ionosphere over the seismic area with better resolution in time

Re: Electric Earthquakes

Proposed multi-layer capacitor model of the crust
indicates that change of dielectric features due to
structural changes, such as liquid dilatency, requires a
change in the electric field at the surface. Amount of the
variation is locally independent from the area. Similarity
of the patterns between the model based simulations using
approximate parameters and the real data based patterns
beside the relatively high correlation between the
anomalies and the earthquakes gives hope for the progress
of earthquake forecast in future.
http://www.emo.org.tr/ekler/35d11c2f995c60b_ek.pdf

I think it would have to be a very complex model, as the orientation of the rock crystal structures would mean current could flow easier laterally in some layers, while in others it would build up locally 'till a dielectric breakdown occurred vertically. Still, any model that could help with predictions of earthquakes could be a lifesaver.

Earthlights / Cold Plasma?

The earthlights are blue on nightvision...which does not make sense to that image technology.
Occasionally we see strange things in the sky that defy logic, and inspire the imagination to wonder whether odd facets of our existence are actually acting on us in our daily lives in ways we can't comprehend. For the most part, these occurrences are completely random happenings; a mere matter of being "at the right place at the right time." But what happens when you have locations around the world where anomalous activity not only occurs repeatedly, but predictably?

One such area is the Lineville Gorge, nestled in the Black Mountain Range in Western North Carolina. Although the Southeastern United States is home to a variety of strange phenomenon that captivates the area locals (and researchers abroad), near the vicinity of Brown Mountain, a long, looming ridge in the heart of the Gorge, a spectacular display of "ghost lights" can be seen on a frequent basis which continue to defy rational explanation.


Dubbed "The Brown Mountain Lights" by the locals, the lights are actually seen all throughout the Lineville Gorge, and are variously described as bright, glowing orbs of colored light that manifest and drift slowly upward, sometimes behaving so strangely that witnesses have been led to wonder whether they might somehow be "controlled" by external forces.

During a recent television shoot I participated in with the National Geographic Channel, my associates in the North Carolina-based L.E.M.U.R. Paranormal Investigations group and I managed to capture a spectacular display of odd illuminations while cameras were rolling. Below is a sneak preview of the new program, called Paranatural, which will be airing soon and appearing on the web to view:

Could that be a sign of cold plasma?

Re: Earthlights / Cold Plasma?

Well I was hoping some of you guys would make a suggestion.
Interesting to have scientific analysis of earthlights with nightvision that defies
common response on that imaging equipment and seems to occur only with these earthlights.
Evidence of cold-plasma? Caused by piezoelectric and pyroelectric effects from the quartz bedrock maybe?

Re: Earthlights / Cold Plasma?

I don't know whether it's cold plasma or not but these lights are similar to the Marfa lights at Marfa, Texas, south of I-10 and north of Big Bend National Park.

A Spin on Earthquakes

Do earthquakes really affect the Earth's spin? Sounds like from this short article that it is purely theoretical math and can't be observed (that should work well for getting a grant to study it!). What would EU would predict? Should electrical change (assuming that is what the earthquake represents) change the Earth's spin? Can the change be verified experimentally? (More importantly, I hope those people are being taken care of in the earthquake aftermath, but this made me curious.)

Earthquake: Shortened the planet's day
by Associated Press

NEW YORK (AP) - Earth's days may have gotten a little bit shorter since the massive earthquake in Chile, but don't feel bad if you haven't noticed.

The difference would be only about one-millionth of a second.

Richard Gross, a scientist at NASA's Jet Propulsion Laboratory in Pasadena, Calif., and colleagues calculated that Saturday's quake shortened the day by 1.26 microseconds. A microsecond is one-millionth of a second.

Re: A Spin on Earthquakes

Hi Talon Thorn,
I think they are assuming that the earthquake ever so slightly decreased the radius of the Earth causing the rotation to slow down, as per conservation of angular momemtum.
What we don't know is if the earthquake was the cause or the effect, or if both the slowed rotation and the EQ were an effect of a third factor?

Re: A Spin on Earthquakes

Yes. I was wondering, if we ignore the concept of gravity being the primary factor, what would the EU explanation be (or would EU even predict a change in the spin rate?). Thanks.

Re: Earthlights / Cold Plasma?

I found this interesting. Earthlights from the Earthquake in Chile
One of the most credible reports of such phenomenon stems from a Chilean news reporter, Cecelia Lagos, who was interviewed by MSNBC and CNN networks. Lagos described "seeing the sky change colors outside her window as her house shook." Lagos describes "I saw through my window, while I was still in bed, I saw the sky changing colors, it was absolutely surreal. I really thought it was the end of the world…I don't know I hope you understand me because I'm not exaggerating really because I saw it through my window like that. That was the most terrifying thing seeing the sky changing colors with the terribly, amazingly, strong movement of the earth, http://gralienreport.com/fortean-phenom ... arthquake/

Below are preliminary values from the International Earth Rotation and Reference Systems Service (IERS) for 2004 December 1st to 30th.
This period encompasses the 26th December 2004, the date of the Sumatran tsunami.
Even though there was a gain (of +0.000152) on the 26-27th, not all of it is attributable to the tsunami as the daily gain, or negative loss, was trending in that direction anyway.

That wouldn't make sense, because decreased radius of a rotating object would cause increased rotational speed, as per conservation of angular momentum / kinetic energy. Also, decreased radius would cause higher density, given if everything underneath is uniformly compact in the first place.
