Earthquakes ad plate tectonics,cause and effect

Another angle of looking at plate tectonic theory

The base of my theory is-some dates are more prone to major quakes than others ,why?
If plate tectonics can ignore some striking co-relation,there is no much hope for any headway by only working on stress strains and ground motions.
I think what we are doing is,interchanging effect as a cause. PLATES ARE THE EFFECTS OF QUAKES and not the cause.In the initial stage there were quakes first and than plates and later plate motions-
If we look with this angle,almost all flaws of plate tectonics can be resolved
