Following on from the AM radio list thread (moved to this section last night), a link for those with a few reels of insulated cable doing not a lot.

The potential link between ELF/VLF and the ULF (0.01 - 10 Hz) as a precursor to an earthquake.

This ties in with research carried out on the effects of the sun's magnetic field(s) on our planet, carried here by the solar wind.
Inequality of the interplanetary current sheet and the movement of the Earth as it orbits through open or broken sections of the interplanetary magnetic field are further compounded by the reversal of the Sun's magnetic polarity - twice - during each solar cycle.

One of the scientific instruments on the Parker Probe in determining how better to measure the changes remotely, which might lead to a reliable warning system. The trouble is the speed at which a repeatable result of such a low frequency can be reported before the impact.

VLF/ELF radiation from the ionospheric dynamo current system modulated by powerful HF signals | Semantic Scholar

Abstract This paper presents results of several campaigns at the Arecibo Observatory using the new HF high power ‘heater’ facility. The specific measurement pertains to detecting VLF/ELF radiation from the ionospheric dynamo current system that has been periodically modified by pulsing the HF...

I have a 10,000 foot coil of magnet wire stuck up in the air about 20 feet that I use for VLF frequency's, I don't hear much on those freqs, but when I'm bored out of my gourd and need to do something, other then look for Jovian noise in the 20 MHz band.

Noises from the Jupiter system are on the rise, peaking in June.

The 20MHz band has become somewhat polluted lately though, thanks in part to cheap LED lighting
