    Gas Hydrates are frozen methane gas that lie just on the continental shelf. They are overlain by thin sediment caps that protect them from defrost so to speak. They constantly bubble as the gas sublimes - turns from solid to gas- and forces its way out of the sediment. On occasion caticlismic amounts of gas sublime spontaneously and free themselves from the deep. As the large bubble rises it depressurizes and expands. At some point the tensile strength of the bubble equalizes and fails. The result is an enormous depth charge or shock wave, along with a gaping vois were there was just water. These are one explanation for ships lost in the Burmuda Triangle. There are great quantities of gas hydrate all along the coast of Florida into the Gulf of Mexico.
