    It kind of makes sense, there’s a large mass of charged particles being deflected by the Earth’s magnetic field, so there must be some kind of corresponding force applied back to the field/the dynamo generating it. Interesting that the leading hypothesis is that it manifests piezoelectrically in rock.

      Yeah I found the fact that its basically the piezoelectric effect (in reverse of how I’m used to thinking about it) at a massive scale, to be fascinating. I’ve always been interested in those fans you put on wood burning stoves, which take some heat energy to spin a fan.

      What are the quantitative forces of a CME versus the Earth’s fields? I feel like any regular charged particle emissions from the sun would be far weaker than a planetary electromagnetic field, especially in terms of induction.

        I suspect that the electrical-force would be … insane, given that Quebec Hydro kept having their grid getting millions of volts, from aurora ( popping their systems )…

        & if you’ve got wet, fractured tectonic-plates, with some fault-zones near-release,

        & then you put a gentle, but IMMENSE geographically, force on them … then the statistical likelihood of stress-release would go up…

        I’m not presuming piezo, but I’m not saying that’s wrong, either…

        I’m just saying that electric-fields have proven, in space, to reach WAAAY farther than we assumed…

        & if we were getting that wrong, then we may be getting it wrong in the Earth, too…

        The primary force would be electric, since it’s from positive & negative plasma being pulled to different locations on Earth…

        & then it should all come down to how-sensitive-the-balance-is, among the tectonic faults, & how that electric current affects those zones, including how it flows through mineralized-water…

        ( that 24h-delay means something: there’s some process which takes that long, for it to tip the balance… )
