Magnetic Anomaly Map of the World

The above map comes from the Commission de la Carte Geologique du Monde. It shows where the magnetics of the Earth fluctuate. Blue represent a weak magnetic tug while red is stronger.
The reason, according to the map makers, for the differences across the world is "igneous and metamorphic rocks" in the crust and mantle. The rocks affect the magnetic pull different than would say, limestone. Less than 1% of the world suffers from extreme magnetic anomalies.
While this may not satisfy those who see a correlation between UFOs, Bermuda Triangle, whatever with magnetic anomalies; it is important to remember that these oddities can be perfectly natural and strong in some areas.
