On http://poleshift.com/ Tells of the two types of pole shift(magnetic reversal)
1. Geomagnetic Reversal aka Magnetic Pole Shift(The Earth’s rotation and orbit are unaffected. The Earth’s crust stays where it is. The change is in the Earth’s Magnetic Field.)
2. Crustal Displacement aka Physical Pole Shift(With a displacement, the Earth’s outer crust moves rapidly and slips relative to the core. The result is that land masses end up being located at a different latitude/longitude than before the shift.) This concept is not accepted by orthodox science.
