The Magnetic Pole has, as far as anyone knows, ALWAYS been shifting, a little bit like the path of a spinning top. Contrary to the comment above, however, it appears to be moving north - that is to say, moving closer to the astronomic pole - the axis of the earth's rotation.
There was never a physical requirement that the magnetic pole coincide exactly with the astronomic pole, although it seems plausible that the two should not be very far apart.
The next bit of theory is also true but it's been exaggerated. The earth's magnetic poles are gradually changing places. This has happened before, based on the alignment of iron-bearing particles in clay formed in various epochs. It's a cycle of THOUSANDS of years. The strength of the magnetic poles will peak - at that time the iron particles in wet mud will uniformly align in one direction. Then, very gradually - over many centuries - the strength of the magnetic pull will diminish; the iron particles in newer clay will be less and less inclined to point all the same way. At some point the magnetic pull will seem to disappear; the iron particles will be completely disorganized and random in their direction.
And then the magnetic pull will begin to gain strength again - but this time reversed -- what had been pull the compass needle to the north will now pull that needle to the south. From this point on, the iron particles in the clay will more and more point in the opposite direction to what particles did several centuries earlier. Eventually this magnetic pull will reach its maximum, then decline and the entire cycle will be repeated.
The earth has probably endured these reverses several times, although the last time the poles were the reverse the only "witnesses" were dinosaurs. The effect is so slow and gradual that many centuries will go by before ordinary people will notice anything about it (although extremely advanced equipment might be able to measure it much sooner). There are no volcanoes, tidal waves, earthquakes, or other conspicuous phenomena expected to accompany this extremely gradual reversal; only that magnetic compasses will no longer be reliable in finding the astronomic pole.
