| The cataclysmic pole shift hypothesis is the conjecture that the axis of rotation of a planet has undergone relatively rapid shifts in location, creating calamities such as massive floods and large scale tectonic events. This type of event would occur if the physical poles had been or will be suddenly shifted with respect to the underlying surface over a geologically short time frame. Among the scientific community, the evidence shows that no rapid shifts in the pole have occurred during the last 200 million years. True polar wander is known to occur, but only at rates of 1° per million years or less. The last rapid shift in the poles may have occurred 800 million years ago, when the supercontinent Rodinia still existed. This hypothesis is almost always discussed in the context of Earth, but other bodies in the Solar System may have experienced axial reorientation during their existences. |
