Pole shift is the hypothesis that extreme movement of the Earth's rotational axis occasionally occurs and can explain catastrophes such as earthquakes and tsunamis. This phenomenon refers to a change in the geographic location of the poles and is distinct from plate tectonics, geomagnetic reversal, and change in axial orientation. Significant shift has not occurred for at least 800 million years and often occur over periods of thousands, if not millions, of years. A slight pole shift over time is normal and harmless, for example, the effects of precession where the angle of the rotation move around like a gyroscope over a cycle of around 26,000 years.
In 1997 a rapid pole shift was predicted for 2000. Unsurprisingly, this did not happen. In 1996 a pole shift was predicted for 2001. This did not happen either. The 2012 pole shift didn't happen either. See the pattern?
The magnetic field can flip. And it can do so relatively quickly, by geological standards; every 300,000-500,000 years. But the pole reversals haven't been correlated to any widespread disasters, such volcanoes, earthquakes, tornadoes, or the dead rising from the grave, so it appears to be nothing worth getting that worried about.
