I think it's telling that none of the authors are geophysicists, and they definitely aren't statisticians either. The causality they're claiming just does not have any physical plausibility. > Dr. Homola states, “In the scientific world, it is accepted that a discovery can be said to have been made when the statistical confidence level of the corroborating data reaches five sigma, or standard deviations.” > Homola co…

May not be causal, but a six-sigma correlation is sure-as-hell interesting.

Edit: I just remembered that today is the 229th anniversary of a meteor fall in Siena, Italy, so big that it established tan undeniable correlation between falling stars and hundreds of chunks of iron lying on the ground. (Putting Newton's prejudice to rest.)

Precursor signals for earthquakes is a field that has about as much credibility as astrology, from the few conversations I've had with professional geologists and planetary scientists. I had a minor and short-lived role in designing a sensor network that might be useful for these kinds of low-signal, high-noise precursors, and I got nothing but strange looks from actual geologists.

> as much credibility as astrology If this sort of scientific astrology ends up providing precursor signals for future earthquakes, why would geologists have a problem with it?

You're assuming an a priori bias. Astrology didn't lose favor because of some societal decree, it lost favor because it had no predictive power. It seems to be the same with analysis of precursor signals, and the subfield apparently went a little nuts and started to sound like quackery and data fudging.

The article points out that the researchers have a premise grounded in science for their correlation. That's the difference between shouting "correlation doesn't equal causation" and actually understanding how correlation is applied.

I would say the crucial thing is actually making a falsifiable prediction, not having a scientific grounding. There are also many "just so" stories that make sense at face value but are not really falsifiable (e.g. Evo psych is full of them). I think the theory here does make some falsifiable predictions, which is great, so guess we will see. But I'm not holding my breath.

Good point. I don't understand their claims, and I don't have a horse in this race, but I'm really interested to understand the mechanism in more detail if it turns out to be correct because it sounds so bizarre.

Or there's a common trigger event, like, say, a large gravitational wave or a passing cloud of weakly interacting matter(dark matter?) which triggers both increased cosmic ray emissions along with earthquakes. Not that I believe any of this, but it seems we're just pulling stuff out of our asses so I figured I'd give it a shot.

>gravity wave LIGO, the gravity wave detecting interferometer, has arms 4 kilometers long. Along that distance, it can detect a change in length one ten thousandth the diameter of a proton. With an instrument that sensitive, it can just barely detect a handful of gravity waves a year, out of the thousands? that occur in the observable universe. Gravity waves are subtle things.

There are different kinds of gravitational waves, LIGO doesn't see them all.

So who is going to be first to launch earthquake inducing satellite weapon?

The US, in 1988 https://www.americaspace.com/2012/01/30/into-the-black-nasas... >

I can't help but think of this horrible movie:

The key claim in the paper ( https://arxiv.org/pdf/2204.12310.pdf ) is that there are detectable changes in cosmic ray activity around 15 days before major seismic events. One posited mechanism is that stuff happens deep in the earth that affects the magnetic field first, and then kicks off some big earthquake. But they don't rule out loopier ideas (like sunspot activity driving changes in the Earth's dynamo that the…

I feel like from my reading given they’re ground based stations that the major earthquake forming causes changes to the magnetosphere making cosmic ray activity appear to increase from the ground.

Were geologists skeptical of the actual data from your sensor network?

(editing to hit a moving target)

We started the study with a good faith survey and intent to use space and ground signals in sync to detect impending earthquakes on nearish term. We had good technologists and scientists. As the study went on it became clear that all the scientists were completely unconvinced. Sure we could have built out the network but it wouldn't have done much. Most the scientists either lost faith or write dissenting opinions as part of the report. We did our job putting out the report but it was clear there was nothing to do after.

One aspect of gravity waves is that other than being extremely weak, they cannot perform work. So they don't cause mechanical forces.

This is not true, and in fact there is a very famous thought experiment called the "sticky bead argument" that was pivotal in developing the consensus that gravitational waves are a real, physical effect and not just a "gauge" effect (an artifact of the coordinate system): https://en.wikipedia.org/wiki/Sticky_bead_argument On the other hand, I definitely agree that gravitational waves are almost certainly too weak to…

I had heard that somewhere before, but it looks like I'm wrong
