The magnetic poles of the Earth are expected to shift by 65 degrees by 2015. The cataclysmic pole shifts which happen throughout history are a geologically rapid shift in the relative position of the geographic locations of the north and south magnetic poles and the axis of rotation of the Earth, creating calamities such as floods and tectonic events. This is not normal precession and changes in axial tilt, but this change is on a much shorter time-scale and will involve relative motion of the spin axis with respect to the earth. The solid Earth can only rotate with respect to a fixed spin axis. Research shows that during the last 200 million years several super-rapid shifts in the Earth's pole were found during mass extinction periods.
