Solar Flares are a commonly discussed phenomenon, which have effects ranging from geomagnetic storms to radio disruptions to absolutely nothing noticeable.

Given that part of the core of the Earth is molten, and magnetic, is there any evidence either way of the core of the Earth producing 'geoflares' like Solar Flares?

  • $\begingroup$ We do know through paleomagnetic techniques that the strength of the Earth's magnetic field varies in location with time, such as the Levantine Iron Age geomagnetic anomaly (LIAA) where a regional magnetic field ~3,000 years ago was twice the strength of the global average. Are you looking for information like that, or are you looking for evidence that these magnetic field variations had some secondary effect? $\endgroup$ – jeffronicus May 26 '18 at 14:30
  • $\begingroup$ Looking for any indication of abrupt geomagnetic effects originating from the core of the Earth rather than the Sun. $\endgroup$ – Onyz May 28 '18 at 18:45
