The northern end of the Cascadia subduction zone, where the Juan de Fuca (JdF) and Explorer (Exp) plates slowly move beneath the North American plate, is gradually shutting down piece by piece, with small pieces of the plate breaking off while the remaining plate continues to subduct until the next tear occurs.
