Shifting Cataclysm/Pole Reversal (Hancock)

The Cataclysmic Pole Reversal Theory is the theory that the earth's magnetic poles have rapidly changed in the past and caused advanced ancient civilizations to be lost when they all died during the cataclysmic event. The complete lack of any direct physical evidence of this advanced civilization having ever existed is said to be because the remains of the civilization are hidden beneath the ice of Antarctica.

The Cataclysmic Pole Reversal Theory Inspiration/Origin

The idea that a magnetic pole reversal is relatively new because the concept that the magnetic poles could move was not proposed until 1997 when Joe Kirschvink proposed true polar wander. Although theories prior to the discovery of the magnetic poles movement did not specifically say that there was a pole reversal, the significant ideas are the same. The general idea is that a global catastrophe caused an advanced civilization to die and be lost in time.
