"I *have* thought about the mechanics and devastation associated by the transport of this volume of water."

This very subject was covered on History, TLC or Discovery. A scientist (Geologist?) posited the mechanics and made predictions on among other thing, the geological scar that would be left. The special claimed he found corrosponding geology. Sorry I don't remember which channel but a look at their shows for sale on DVD might turn it up. "

It would have to be one heck of a scar, since we're talking a volume of water on the order of one billion cubic miles. Billion with a B.
Now, is there any known physical process that would cause that volume of water to pop out of the earth like a jack-in-the-box? Then neatly tuck itself back in? Or are we reduced to invoking miracles here?
