"By definition, the Vile Vortices would be miserable whirlers but actually they are twelve vertex points of a planetary grid (see Figure 1) originally plotted by Ivan T. Sanderson, a naturalist and paranormal investigator. Sanderson first coined the term, “Vile Vortices”1 in his article “The Twelve Devil’s Graveyards Around the World” (Saga magazine, 1972).
The best-known Vile Vortices are the Bermuda Triangle, the Dragon’s Triangle (Devil's Sea), and the South Atlantic Anomaly. However, each of these twelve geographic areas is credited with instances of magnetic anomalies and other unexplained phenomena."
