The Bermuda Triangle, sometimes called the Devil's Triangle, is reputedly an area in the western part of the North Atlantic Ocean. The triangle doesn't exist according to the US Navy and the name is not recognized by the US Board on Geographic Names.
However, a number of aircraft and surface vessels are said to have disappeared in the triangle under unknown circumstances. Popular culture has attributed various disappearances to the paranormal or activity by extraterrestrial beings. Documented evidence indicates that a significant percentage of the incidents were spurious, inaccurately reported, or embellished by later authors. Contrary to popular belief, insurance companies do not charge higher premiums for shipping in this area.
Triangle writers have used a number of supernatural concepts to explain the events. One explanation pins the blame on leftover technology from the mythical lost continent ofAtlantis. Sometimes connected to the Atlantis story is the submerged rock formation known as the Bimini Road off the island of Bimini in the Bahamas, which is in the Triangle by some definitions. Followers of the purported psychic Edgar Cayce take his prediction that evidence of Atlantis would be found in 1968 as referring to the discovery of the Bimini Road. Believers describe the formation as a road, wall, or other structure, though geologists consider it to be of natural origin.
Other writers attribute the events to UFOs. This idea was used by Steven Spielberg for his science fiction film Close Encounters of the Third Kind, which features the lost Flight 19 aircrews as alien abductees.
Charles Berlitz, author of various books on anomalous phenomena, lists several theories attributing the losses in the Triangle to anomalous or unexplained forces.
Compass variations
Compass problems are one of the cited phrases in many Triangle incidents. While some have theorized that unusual local magnetic anomalies may exist in the area, such anomalies have not been found. Compasses have natural magnetic variations in relation to the magnetic poles, a fact which navigators have known for centuries. Magnetic (compass) north and geographic (true) north are only exactly the same for a small number of places – for example, as of 2000 in the United States only those places on a line running from Wisconsin to the Gulf of Mexico. But the public may not be as informed, and think there is something mysterious about a compass "changing" across an area as large as the Triangle, which it naturally will.
Gulf Stream
The Gulf Stream is a deep ocean current that originates in the Gulf of Mexico and then flows through the Straits of Florida into the North Atlantic. In essence, it is a river within an ocean, and, like a river, it can and does carry floating objects. It has a surface velocity of up to about 2.5 metres per second (5.6 mi/h).A small plane making a water landing or a boat having engine trouble can be carried away from its reported position by the current.
Human error
One of the most cited explanations in official inquiries as to the loss of any aircraft or vessel is human error. Human stubbornness may have caused businessman Harvey Conover to lose his sailing yacht, the Revonoc, as he sailed into the teeth of a storm south of Florida on January 1, 1958.
Violent weather
Hurricanes are powerful storms, which form in tropical waters and have historically cost thousands of lives lost and caused billions of dollars in damage. The sinking of Francisco de Bobadilla's Spanish fleet in 1502 was the first recorded instance of a destructive hurricane. These storms have in the past caused a number of incidents related to the Triangle.
A powerful downdraft of cold air was suspected to be a cause in the sinking of the Pride of Baltimore on May 14, 1986. The crew of the sunken vessel noted the wind suddenly shifted and increased velocity from 20 mph to 60–90 mph. A National Hurricane Center satellite specialist, James Lushine, stated "during very unstable weather conditions the downburst of cold air from aloft can hit the surface like a bomb, exploding outward like a giant squall line of wind and water."[30] A similar event occurred to the Concordia in 2010 off the coast of Brazil.
Methane hydrates
Main article: Methane clathrate
Publications by the USGS describe large stores of undersea hydrates worldwide, including the Blake Ridge area, off the southeasternUnited States coast.[35] However, according to other papers of theirs, no large releases of gas hydrates are believed to have occurred in the Bermuda Triangle for the past 15,000 years.An explanation for some of the disappearances has focused on the presence of large fields of methane hydrates (a form of natural gas) on the continental shelves.[31] Laboratory experiments carried out in Australia have proven that bubbles can, indeed, sink a scale model ship by decreasing the density of the water; any wreckage consequently rising to the surface would be rapidly dispersed by theGulf Stream. It has been hypothesized that periodic methane eruptions (sometimes called "mud volcanoes") may produce regions of frothy water that are no longer capable of providing adequate buoyancy for ships. If this were the case, such an area forming around a ship could cause it to sink very rapidly and without warning.
