Bermuda Triangle
Most of us have heard about "Bermuda Triangle" which is known for making airplanes and ships disappeared. After some research on google, I found some interesting stuff about it.
In the Bermuda Triangle, methane gas is known to be present and the release of that gas could cause not only boats to sink, but also aeroplanes to crash. The gas could cause an explosion if it comes in contact with the hot engine of a plane.
How does methane gas formed?
Massive landslides often occur along the North American continental shelf, which lies to the north of the Bermuda Triangle. Such land slumps can occur over a large area bringing down huge boulders which rupture the layer of gas hydrate beneath the sea floor, freeing the gas that is trapped beneath the hydrate ‘cap’ and also liberating huge amounts of methane trapped within the hydrate itself. The moment a methane gas pocket ruptures a vast reservoir of gas suddenly surges from the seabed, rising up in a huge plume before erupting on the surface within seconds and without warning. A ship caught in such a blowout would be doomed; the water beneath it would suddenly become much less dense, sinking it in a matter of moments.
Conditions are ideal for the formation of this gas in areas of permafrost. Another area is the deep sea floor where the pressure and the temperature are right for the creation of this gas.
