Reversals in the Earth’s magnetic field means, the magnetic poles of the Earth have shifted in short amounts of time, and many more times than once or twice; and the shifts (which are recorded in ferrous rocks that used to be molten lava) are not related to continental drift.

Something like every 300,000 years.

Thank you for your helpful response. I do remember the 2004 Indian Ocean earthquake causing a measurable shift of this earth, and then again with the recent quake near Japan. What I have not read is which direction from polar north the earth shifted.
