davidicke.com | 'At some point the drilled hole in the earth will enlarge itself beneath the wellhead to weaken the area the wellhead rests upon. The intense pressure will then push the wellhead off the hole allowing a direct unrestricted flow of oil, etc.  

The hole will continue to increase in size allowing more and more oil to rise into the Gulf. After several billion barrels of oil have been released, the pressure within the massive cavity five miles beneath the ocean floor will begin to normalize. 

This will allow the water, under the intense pressure at 1 mile deep, to be forced into the hole and the cavity where the oil was. The temperature at that depth is near 400 degrees, possibly more. The water will be vaporized and turned into steam, creating an enormous amount of force, lifting the Gulf floor. It is difficult to know how much water will go down to the core and therefore, its not possible to fully calculate the rise of the floor. The tsunami wave this will create will be anywhere from 20 to 80 feet high, possibly more. Then the floor will fall into the now vacant chamber. This is how nature will seal the hole.
