All about Bermuda triangle

 The Bermuda Triangle, also known as the Devil's Triangle, is an urban legend focused on a loosely-defined 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 idea of the area as uniquely prone to disappearances arose in the mid-20th century, but most reputable sources dismiss the idea that there is any mystery.

Triangle area

The Gaddis Argosy article delineated the boundaries of the triangle, giving its vertices as Miami; San Juan, Puerto Rico; and Bermuda. Subsequent writers did not necessarily follow this definition. Some writers gave different boundaries and vertices to the triangle, with the total area varying from 1,300,000 to 3,900,000 km² (500,000 to 1,510,000 sq mi)."Indeed, some writers even stretch it as far as the Irish coast." Consequently, the determination of which accidents occurred inside the triangle depends on which writer reported them.

Larry Kusche

Larry Kusche, author of The Bermuda Triangle Mystery: Solved (1975), argued that many claims of Gaddis and subsequent writers were exaggerated, dubious, or unverifiable. Kusche's research revealed a number of inaccuracies and inconsistencies between Berlitz's accounts and statements from eyewitnesses, participants, and others involved in the initial incidents. Kusche noted cases where pertinent information went unreported, such as the disappearance of round-the-world yachtsman Donald Crowhurst, which Berlitz had presented as a mystery, despite clear evidence to the contrary. Another example was the ore carrier recounted by Berlitz as lost without trace three days out of an Atlantic port when it had been lost three days out of a port with the same name in the Pacific Ocean. Kusche also argued that a large percentage of the incidents that sparked allegations of the Triangle's mysterious influence actually occurred well outside it. Often his research was simple: he would review period newspapers of the dates of reported incidents and find reports on possibly relevant events like unusual weather, that were never mentioned in the disappearance stories.

Kusche concluded that:

• The number of ships and aircraft reported missing in the area was not significantly greater, proportionally speaking, than in any other part of the ocean.

• In an area frequented by tropical cyclones, the number of disappearances that did occur was, for the most part, neither disproportionate, unlikely, nor mysterious.

• Furthermore, Berlitz and other writers would often fail to mention such storms or even represent the disappearance as having happened in calm conditions when meteorological records clearly contradict this.

• The numbers themselves had been exaggerated by sloppy research. A boat's disappearance, for example, would be reported, but it's eventual (if belated) return to port may not have been.

• Some disappearances had, in fact, never happened. One plane crash was said to have taken place in 1937, off Daytona Beach, Florida, in front of hundreds of witnesses; a check of the local papers revealed nothing.

• The legend of the Bermuda Triangle is a manufactured mystery, perpetuated by writers who either purposely or unknowingly made use of misconceptions, faulty reasoning, and sensationalism.

In a 2013 study, the World Wide Fund for Nature identified the world's 10 most dangerous glasses of water for shipping, but the Bermuda Triangle was not among them.

Paranormal explanations

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 of Atlantis. 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, but the Bimini Road is of natural origin.

Some hypothesize that a parallel universe exists in the Bermuda Triangle region, causing a time/space warp that sucks the objects around it into a parallel universe.  Others attribute the events to UFOs. Charles Berlitz, an author of various books on anomalous phenomena, lists several theories attributing the losses in the Triangle to anomalous or unexplained forces

Natural explanations

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 that navigators have known for centuries. Magnetic (compass) north and geographic (true) north are exactly the same only 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 major surface current, primarily driven by thermohaline circulation 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 maximum surface velocity of about 2 m/s (6.6 ft/s). 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, Revonoc, as he sailed into the teeth of a storm south of Florida on January 1, 1958

Violent weather

Hurricanes are powerful storms that form in tropical waters and have historically cost thousands of lives 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. Many Atlantic hurricanes pass through the Triangle as they recurve off the Eastern Seaboard, and, before the advent of weather satellites, ships often had little to no warning of a hurricane's approach.

A powerful downdraft of cold air was suspected to be a cause in the sinking of Pride of Baltimore on May 14, 1986. The crew of the sunken vessel noted the wind suddenly shifted and increased velocity from 32 km/h (20 mph) to 97–145 km/h (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." A similar event occurred in Concordia in 2010, off the coast of Brazil.

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. 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 the Gulf 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.

Publications by the USGS describe large stores of undersea hydrates worldwide, including the Blake Ridge area, off the coast of the southeastern United States. However, according to the USGS, no large releases of gas hydrates are believed to have occurred in the Bermuda Triangle for the past 15,000 years
