Alexander, stick to the spreadsheets.
The plates move because at one edge crust is being created by an up-swelling of lava, this pushes one plate against another.
If we could tap into the heat at the up-swelling. In, admittedly, a big way we could reduce the inter-plate pressure. The only other way to reduce such pressure is by draining the lava via volcanoes. God-like. I know, but dotting these time bombs around the globe is no less god-like and dangerous all the way.
