I agree. Plate techtonics is nothing more than a series of puzzle pieces. My theory is also that the energy wave an initially strong quake can be tracked across a plate, and that with distance, the intensity decreases. There were a series of quakes this year that demonstrated this. The initial quake started in the pacific, and the energy traveled from west to east, causing smaller quakes, each decreasing in magnitude, the greater the distance from the origin.
Basically, its all one energy chain reaction.
