Can Electric Signals In Earth's Atmosphere Predict Earthquakes? (sciencemag.org)
sciencehabit writes with interesting news about a possible new avenue for earthquake prediction. Sciencemag reports: "Ask seismologists when they'll be able to predict earthquakes, and the answer is generally: sometime between the distant future and never. Although there have been some promising leads over the years, the history of earthquake forecasting is littered with false starts and pseudoscience. However, some scientists think that Earth's crust may give hints before it ruptures, in the form of electromagnetic anomalies in the ground and atmosphere that occur minutes to days before an earthquake. Now, researchers are sharing their evolving understanding of these phenomena—and how they might be used to predict deadly quakes."
Another question being put forth as some sort of possibility.... sorry, no evidence to support this at all and it doesn't even pass the common sense test.
Yes.

No.
By what mechanism do they expect stresses in rocks to produce electric fields?
APK likes to ask for responses to the same things over and over. Maybe he just likes the responses?
in my experience, they predict lots of things. time for dinner.
Correlation is not causation... or in this case, any chance that someone invented an earthquake machine and is using to it to cause quakes?
Solar activity should be considered a major contender for detecting earthquakes, ongoing research at SuspiciousObservers.org. Electrical activity in the earth's atmosphere is too little too late.
However, scientists have yet to agree on a mechanism by which the crust could create electromagnetic signals. One idea is that rocks can generate positive charges when heated or stressed in the build-up to an earthquake, says Friedemann Freund, an adjunct professor of physics at San Jose State University in California and a senior scientist at NASA’s Ames Research Center in Mountain View, California. “When you stress a rock, it turns into a battery,” Freund says. “Not an electrochemical battery that you find in your car, but a new type of semiconductor battery that produces electrons and holes.”
These “holes” are positive charges that come from molecular defects known as peroxy bonds, which occur in most crystalline rocks and involve two oxygen atoms bonded together instead of to silicon or another element. At high temperatures and pressures, peroxy bonds break, causing them to pull in an electron from a neighboring atom, and leave behind a positively charged “hole.” This creates a chain reaction of electrons flowing toward the peroxy defect, effectively creating a cloud of positive charge flowing away, potentially to the surface and beyond.
My eyes reflect the stars and a smile lights up my face.

Just check on Lex Luthor's recent real estate purchases and make friends with his escrow agent. Shouldn't be too hard.
The mechanism by which stresses in rocks produce electric fields.
Alex, what is piezoelectricity?
Better known as 318230.
The first thing I thought of was pressure fluctuations on naturally occurring piezoelectric crystals
Perhaps we can trick Betteridge.... "Electric Signals In Earth's Atmosphere Predict Earthquakes, false or true?"
love is just extroverted narcissism
No.
By what mechanism do they expect stresses in rocks to produce electric fields?
There is a well known mechanism called the piezoelectric effect by which stress in a crystal produces an electrical field. Quartz, for example, is a well-known piezoelectric material...and also a component of igneous rock.
So, it's not completely implausible.

This has long been known, and as usual not super new news.
Even in 1975 ("Haicheng Earthquake" ), schoolchildren who had been given electrical measurement kits began to detect unusual fluctuations in ground voltage. This earthquake is one of the few that have reasonably legitimately been claimed to have been predicted on the order of days in advance, with significant population lives saved by concrete action beforehand (could be fortuitous coincidence, but they definitely saw the warning signs -- and note that this earthquake is one of the many documented where animals foretold the earthquake through unusual activity).
There have also been reports of the atmosphere turning purple/blue around the location of an impending earthquake, which is probably what led to the work here. What is new is some more consistent effort to try to detect the precursors.
My uninformed interpretation of the phenomenon is that geophysical / piezoelectric stress in the rocks induces voltages/currents in the ground, which in turn cause atmospheric electrical effects that can be detected.

By what mechanism have you come to the conclusion that it's impossible and the idea is immediately dismissable?
Talk about argument from ignorance...

Quartz. Squeeze it, it creates a charge. The last 100 or so years of radio technology has depended on this. Earthly rocks got lots of it.
But.... yawn... pretty sure I read this like 40 years ago in Popular Science or Popular Electronics or some such.
Build an earthquake detector!
Just look where the biggest concentration of CO2 is located - after all, it's blamed for all other ills of the Earth! So that must be it...
The piezoelectric effect, you nimrod high-school dropout.
The same mechanism that makes the piece of rock in your wristwatch oscillate. Are you as stupid and obnoxious as you appear to be?

You should probably stop offering your opinion if you have no idea what you're talking about.
Apply a current to a piece of quartz and it vibrates. Squeeze it and it generates a current.
But you seem hell bent on sounding like an idiot, so you've succeeded.
so the electric signal of the quake will get to you faster than even the p-wave
that would give birds time to fly up into the air, and people time to get into a doorway, but probably not enough time to get out of a really tall building
You're the exact type of complete fucking moron who would have argued that it is impossible to break the sound barrier or that man cannot reach the moon.
There is no such thing as a vacuum or microorganism either.
Please do us a favor, and stop communicating with people.
.... and decided that all the crap in it was based on scientific fact.
They do not need scientists: italian radio amateurs are very busy detecting radio signals emitted from earthquakes!
Watch it. You're messing with the fabric of space-time now.
Not nearly as well as sheep's bladders.
Thank you for posting this. I have been considering getting back into ham radio after quitting it years ago, but given the stuff they are doing, for sure I will keep myself miles away from that!
So, are you going to apply your sig to yourself?

By what mechanism do they expect stresses in rocks to produce electric fields?
All of this, and MORE can be explained by the Electric Universe Theory. Any gaps in EUT are filled in by TIMECUBE.
It's been a long time since I've visited that site. Looks like they've had a major redesign.

It is good to hear they were cleared. That seemed like the politician/managers faithful fallback "someone must be to blame!" I hadn't heard about the outcome of the trial yet, thanks for the information.

I knew about the piezoelectric effect before graduating high school, yes. Go back to your software, you thick-skulled autist.
You *do* realize that by your own weak insult, you are admitting that a teenager knows more about the real world than you! You're not even smart enough to come up with an insult that doesn't blow up in your face!!
When I was at Stanford in the 1970s there were several promising methods associated with at least one major earthquake. They included the Russian acoustic - shear velocity ratio which was supposed to change before earthquakes due to an increase in microcracks. The Chinese had two successes with farmyard animal anomalies, but missed the most costly Chinese quake in the 20th century, the Tianjin right at the doorstep of Beijing science academies. Heliem soil anomaly increases seemed promising too. The US funded studies in all these methods. But none ever really predicted another quake. "Prediction" became a nasty joke wordk on scientific resumes. The field dribbled on with more narrow problems such as early warning systems to give 30 seconds or so early notice of damaging seismic waves or tsunamis. And less rigorous "forecasting"- windows of increased probablity rather than a specific prediction.
Yet the prediction effort sunders on. A Greek group claimed ground resistance anomalies associated with quakes, but no one could reproduce their results. A Stanford group saw a magnetic jump just before the large 1989 San Andreas quake, but this was never seen again in later quakes. A Russian group calimed their secretive "circles of probability" method predicted the same quake, but missed other quakes. And ionospheric anomalies, the topic of this slashdot, are startign to be looked at. All these methods have received some funding from government agencies, so its not like they are completely ignored. The USGS had a huge and expensive effort to instrument Parkfield California for a large quake which happens about every 20 years. The quake did happen a dozen years later than expected. There werent any promising anomaly signals.
The most promising method still seems to be previous seismicity and fault mapping. These hint at the possible size and location of earthquakes. Its been known for a century that quakes tend to obey a size-frequency law. That means when you see a persistent swarm of small or medium quakes like in northwest Nevada, central Oklahoma, and eastern Tennessee, is this a sign of something larger to come?
These seismicity data are are online in public databases for anyone to test their pet analysis theory on.
I was merely pointing out that children use insults to belittle others. That or you never progressed socially since around middle school. So, the question is, who is acting more like an autist here? You insult someone you don't even know for no apparent reason, or me for pointing out your needless insults as coming from someone who is socially still in middle school.
I knew about piezoelectric effect in high school too, wow, aren't we special together. But I don't go around throwing insults at others to make myself feel better, while you do.
you nimrod high-school dropout.
I point out your needless insults, and you think I am insulting you? It is only an insult because you think you are being insulted, instead realize you are the one acting abnormal here, and I am the one trying to have an adult conversation. Perhaps when you learn the difference, maybe you can join the adult table.
