25. Although the transition described here is more common, trench-perpendicular to trench-parallel transitions in φ have also been observed, for example, in Kamchatka and Alaska. These backward transitions are not easily explained by our model; however, because both Kamchatka and Alaska are located near slab edges, local processes may affect these regions.
