I am not certain about the partial crustal displacement. When you apply the "OM" factor and the ramped up electric waves from the sun to an already dynamic system, it seems like the plates would want to organize into the most efficient spacing. As the video showed what happens when you apply electricity to sand, it lifts and forms a ring on the outer edge. If the sound was at the correct frequency, that would also help to lift.

You also get wet sand columns under the plates. Could this be the source of the booms? It pulls moisture to it. His model was above ground. What happens below?

That is what I get for being curious. More questions.

Good night.
