神秘的北纬30度分析解析教程文件

The unusual events date back in recorded history to 1493 and the first voyage of Christopher Columbus (1451–1506) to the New World. It is recorded in his log（航行日志） that the reading of the compass was askew（歪斜的） within the area. Later from the year 1880 to 1976, there were some 158 disappearances occurred in this region. The disappearance in 1945 might be better known to us. Five navy aircrafts took off from a naval airport in southern Florida in perfect flying weather, on a routine training mission. Less than two hours later, they were completely lost, and the rescue plane sent to search for the missing aircraft, disappeared without trace，too.

The Bermuda Triangle, also known as the Devil's Sea, is a triangle-shaped stretch of ocean between Miami （迈阿密）, Bermuda and Puerto Rico（波 多黎各） in the western part of the North Atlantic Ocean.
The area is one of the most heavily traveled shipping lanes in the world, with ships crossing through it daily for ports in the Americas, Europe, and the Caribbean Islands.

Methane hydrates 可燃冰
An explanation for some of the disappearances has focused on the presence of vast fields of methane hydrates (a form of natural gas) on the continental shelves . 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.
