The abstract was so ambiguously-worded that nothing specific about the 'anomalies' could be deduced, requiring the viewer to sign in, and god-knows- what afterwards, to gain access to the PDF.
One comment made though, concerned the anomalies having nothing to do with the Sun. Ruling out space weather.
* 'Diurnal' is a man-experienced event.
* Earth is 'unaware' that 'days' exist.
* Sun / Earth / Lunar tidal effects go on, day and night, 24-7, 365.
* If the magnetosphere has a variability in its vertical force component, the Earth Dynamo itself would be the culprit.
* If it's the dynamo, then it's about internal convection and plumes.
* That will have to do with solar system gravitational tidal effects, the Earth-wave, and radioactive decay of heavy elements in Earth's interior.
* IEEE might want to look at all the other phenomena that occur pre-earthquake. Run their statistical models on them as well. See if they're experiencing a symptom of something else, instead of a driver.

Like animals' anxiety levels?

Animals that follow the Earth's magnetic field for migration are impacted by the wandering magnetic poles.

Right! And we'd want to examine the cataloged migration calendar events for a checklist of times when that happens, seasonally.
Some migrating species will fly day and night, so they're experiencing diurnal variability if it's there.
And if there are X, Y, and Z of Earth's magnetic lines of flux, we need to know which ones affect which species.
Here in Texas and Oklahoma, we're experiencing thousands of earthquakes now, caused by hydrofracking oil and natural gas wells. These petroleum-bearing formations were located in part, by their paleo thermoremanent magnetization from hundreds of millions of years ago.

No one seriously into earth quake prediction tries to predict M4 earthquakes or makes a watch area thr size of the lower 48. So that right there is a strawman. Plus no one cares about M4 earth quakes.
The latest science is detecting abrupt changes in the earth's magnetic field minutes before the fault snaps on M6 and bigger quakes.
USGS will continue with "there is no such thing as earth quake prediction" until after they them selves start issuing earth quake warnings. And then they will take credit for it.

So, if the change in magnetic field changes at the speed of light, and the acoustic waves travel through the lithosphere much slower, you would always expect to 'register' the delta- magnetic-flux in advance of the P-waves / S-waves, even though they started from the same, identical, place and time.
There isn't any prediction capability. You're only experiencing a time-lag, between a 'field' velocity and a 'wave' velocity. Nothing unique.
And since the total stress required to fracture any fault asperity cannot be known in advance, and a small fracture and displacement could conceivably unzip a larger asperity, it seems that all seismic events would be of significant interest if they could conceivably trigger contiguous events.
It's difficult to place sensor - transmitters, which can withstand 1,500- Celsius, and over-pressures at 400-kilometers below ground. And until they can do so, we can expect these time lags to prevail.
A cardiologist can watch your blood pressure, but they can't predict if you'll develop an aortic dissection.

The National Earthquake Information Center gives this value for annual earthquake incidence, globally.

All you need is a few minutes warning to get outta buildings and away from stuff that can fall on you.
The sensors appear to sit at ground level, maybe as deep as a water well. No special technology required.
If they had some government money then maybe it could be a thing. But according to the government earthquakes can't be predicted, even by a few minutes.

It's still worthwhile to monitor smaller quakes because they come in clusters and might precede, else mitigate, larger earthquakes.

The whole process is laid out here: www.everythingselectric.com/claude-blot/

Claude Blot in 1969 discerned that earthquakes originate in the Benioff zone in the lower reaches of the Earth's crust. These percolate upward with the timing dictated by electrical activity in the upper crust, which in turn is dictated by the immediate electric[o-magnetic]al environment of the Earth.

The earthquake forecasters don't predict small ones but the do use the small ones or lack of small ones to make warnings for thr big ones.
