What are you insinuating? Don't be shy!
I have acknowledged that ringwoodite contains (a small percentage of) water. So, yes: It is, of course, possible to extract that water.
I suppose that heating might be one way to accomplish that.
Those deep regions of the Earth where ringwoodite is found are ALREADY hot. And yet they are NOT currently shooting up any "fountains" of water towards the Earth's surface.
So, don't be coy! If you insist upon an actual physico-mechanical mechanism for the Biblical narrative: Out with it! What physical process caused the (already hot) ringwoodite to suddenly release the water locked up inside it?

You seem like the sort of fellow who would be familiar with Charles' Law and Boyle's Law.

An increase in heat, a decrease in pressure or a combination of both.
What regulates the thermostat of our nuclear reactor core? I don't know. What regulates the pressure of the planet? I don't know, but I can surmise events that might effect them.
Perhaps the solar system passed through the path of a cosmic neutron or neutrino stream, and it provided just enough energy to cause the water contained in the ringwoodite to change states.
