Methane in the Gulf

Not sure how true this is. I came across this while browsing through google and it sounds pretty scary
Methane may cause Tsunami
Methane may cause Tsunami
quote:
After several billion barrels of oil and billions of cubic feet of gas have been released, the massive cavity beneath the ocean floor will begin to normalise, allowing freezing water to be forced naturally into the huge cavity where the oil and gas once were. The temperature in that cavity can be extremely hot at around 150 degrees celsius or more. The incoming water will be vaporised and turned into steam, creating an enormous force, which could actually lift the Gulf floor. According to computer models, a second massive tsunami wave might occur.

If the toxic gas bubble explodes, it might simultaneously set off a tsunami travelling at a high speed of hundreds of miles per hour. Florida might be most exposed to the fury of a tsunami wave. The entire Gulf coastline would be vulnerable, if the tsunami is manifest. Texas, Louisiana, Mississippi, Alabama and southern region of Georgia might experience the effects of the tsunami according to some sources.

Yeah just like that massive Tsunami from the IXTOC blowout. Remember that one?

not just the tsunami, methane is a poisonous gas

Theres no tsunami and tons of methane is released from natural sources everyday and no one dies from it.

This is completely insane bullshite.
It is possible for a methane bubble of size to endanger a fishing vessel. A Tsunami IS NOT like a normal wave. In fact, unless there were a massive upheaval of a large portion of the ocean seafloor (Think several hundred, even several THOUSANDS of miles of it)...no dice.

How would it explode under water? It would need a source of ignition (ie a spark or open flame) and unless something like an ROV or other item dealing with the leak cap effort were to cause one, there is no natural means (that I know of) to create an ignition source at that depth.
Also, at that depth (pressure) isn't the boiling point of water greatly increased? I would think that at a depth of 5000 feet, water pressure would make the boiling point rise to a point that 150 degrees C would not come close to turning seawater to steam.

Sorry, couldn't find one with psi and deg F, but yes it would have to get pretty darn hot and the water down there is very cold...
