The Bermuda Triangle
Can anyone explain the strange happenings in the Bermuda Triangle?
On 5 December 1945, five Avenger torpedo bombers of the US Navy took off from Fort Lauderdale on a routine training flight over the Atlantic. They did not return. A large Mariner flying boat sent to search for the missing aircraft also failed to return. No trace has ever been found of the six planes or the 27 crew members. As a result of this incident, it was discovered that quite a few ships and aircraft had also been lost, apparently without explanation in the triangular area off the south-east coast of the United States bounded by Bermuda, Puerto-Rico and Florida. Explanations for these disappearances were put forward: now the work of Dr Richard McIver offers the best, most scientifically credible, explanation of the mystery surrounding the Bermuda Triangle - methane hydrate.
Methane hydrate was first encountered in the 1920s and 1930s in the early days of the American and Soviet gas industries. Natural gases (a mixture of flammable gases found in the Earth's crust, methane, ethane, butane and propane) were being piped across the Atlantic but occasionally the pipes would become mysteriously plugged up. The cause of this was thought to be ice, but was actually found to be a new substance - hydrate. All gases except for helium, hydrogen and neon can form hydrates if enough gas and water are present, if the pressure is high enough and if the temperature is low enough. These conditions can be found naturally occurring on earth, and methane hydrate has been found to exist in huge quantities in many parts of the sea floor and is concentrated in some places on continental slopes. The structure of methane hydrate allows a large amount of gas to be 'captured'; if this were to dissociate, then even a small area could cause a large gas release. Sediment piles on continental slopes such as in the Bermuda Triangle, can 'slump' - such slumps are known to be happening today. Sediment from river mouths piles up on the slopes of the edge of continental plates, but is unstable and can tumble down. When this happens, it can cause the removal of the hydrate layer, releasing the methane gas trapped below.
Methane gas bubbling up through the sea will cause an area of decreased density; ships will lie lower in the water and will be swamped by the least wave; also methane gas when mixed with air in the correct proportions is highly explosive. This could account for the mysterious disappearances of both ships and aircraft. Why has no trace of them ever been found? All this activity on the sea bed occurs at the edges of tectonic plates, where there is constant activity as a result of the pressures beneath the earth's crust; any wreckage sinking to the bottom would be lost beneath the moving plates. This is the best theory to date of the Bermuda Triangle mystery; the fact that such large gas blow outs occur not only in this area but also in the Caspian Sea, and indeed around all the continents gives great credence to this theory.
The Bermuda Triangle (百慕大三角) is also called Devil’s Triangle. It is an imaginary① area in the Atlantic Ocean. It extends② more than one million square kilometers between the island of Bermuda, the coast of southern Florida and the island of Puerto Rico. Drawing an imaginary line to link these three places creates the three sides of a triangle.
The mystery surrounding the Bermuda Triangle is that the area seems to be extremely dangerous to airplanes and ships. Some people believe that at least fifty ships and twenty planes have disappeared there during the past one hundred years.
The accident that first suggested the danger of the Bermuda Triangle was the disappearance of five American Navy planes in 1945. The planes carried fourteen people on a training flight. They never returned. And a plane sent to search for them also disappeared. Newspaper reporters and other writers called the planes the Lost Patrol. They began trying to explain the tragic events. Some of the explanations were strange. One writer said there were powerful forces under the water. These forces interfered③ with communication devices and caused planes to crash and ships to sink. Another writer said creatures from outer space guarded the area. These creatures pulled the planes and ships to another planet. Some critics④ said the Bermuda Triangle stories were false. They said most of the events that took place in the area could be explained scientifically. And they said most of the accidents linked to the Bermuda Triangle did not happen there. Critics said only about five real accidents happened within the triangle’s borders. The United States Coast Guard agreed. It said the stories about the Bermuda Triangle were mostly science fictions and should not be taken seriously.
