The Bermuda Triangle, also known as the Devil's Triangle, is a region in the western part of the North Atlantic Ocean where a number of aircraft and ships are said to have disappeared under mysterious circumstances. The triangle is loosely defined by points in Miami, Florida, San Juan, Puerto Rico, and the mid-Atlantic island of Bermuda. Over the years, many ships and planes have been lost in this area with some disappearances attributed to paranormal or extraterrestrial phenomena by popular culture. However, most scientists provide rational natural explanations such as rapid weather changes or methane gas eruptions from the sea floor. The true cause of the disappearances in the Bermuda Triangle remains unexplained.
