Radiation Belt Visualization (IMAGE) NASA/Goddard Space Flight Center Caption During a strong geomagnetic storm, electrons at relativistic energies, which are usually only found in the outer radiation belt, are pushed in close to Earth and populate the inner belt. While the electrons in the slot region quickly decay, the inner belt electrons can remain for many months.
