The Bermuda Triangle or "Devil's Triangle" is a triangular-shaped area off the coast of Florida that is famous for reports in which strange disappearances occur and magnetic compasses go haywire. The area is situated in the Atlantic Ocean and is generally thought of as having apexes at Miami, Bermuda, and San Juan. This area contains some of the deepest sub-oceanic trenches in the world, encompasses the fast-moving waters of the Gulf Stream, and has frequent strong water spouts and violent storms, making at least some of the reported odd phenomena attributable to human error or mishap.

The US Coast Guard acknowledges the fact that there are definite environmental anomalies in this area, but goes on to say that human error is by far the more bizarre phenomena that happens in these waters. The area sustains heavy traffic, both by air and by sea, and certainly accidents are bound to happen. Inexperienced mariners or pilots who don't take into account variations in compass readings or environmental anomalies in the area can and do get into serious trouble, accounting for many of the unexplained disappearances in the area.
