Depends on how low the frequency is :)
But indeed I'm not an expert by any means on magma properties, perhaps someone else can chime in. If magma is conductive then even less radiation goes through.
Keep in mind at extremely low frequencies the whole Earth is in mid-field or near-field of emissions, so it doesn't behave attenuated like light rays.
- ncmncm 7y agoMagma is, for practical purposes, infinitely conductive. Only atmospheric EM events are plausible causes of spurious correlated events.
- darkmighty 7y agoEven an infinitely conductive sphere does not screen the quasi-static near field very well. Although the delay is probably going to be weird, greater than direct visibility. Atmospheric EM events indeed are what comes to mind.
