Abstract
Two plate motion models are examined concerning the inclusion collapse theory of deep earthquakes. The first is the steadystate subduction model in which the entire length of the subducted portion of the plate is considered to be in uniform motion within the mantle. The second is the variable motion subduction model in which the plate is assumed to be "hung up" with the continental lithosphere at lock zones that must be broken before motion of the plate into the mantle can occur. The effect of pressure on plate density, the effect of plate density on down-dip stress distribution, the seismicity gaps within a subducted plate, and the plate motion and petrogenesis are also considered.
