forearc across Central Greece well north of the future Gulf of Corinth. At some point the new forces began to pull apart the former strike-slip fault north of Anatolia merging it with the subduction, and pulling out a separate forearc from the previously docked coastal ridge, consisting of strips of the Outer Hellenides in the Ionian and some other zones. CW rotation of the subduction zone Slab rollback moved the subduction zone away from, but not parallel to, the continental coastline. A bathymetric view of the current configuration suggests that an angle was generated on the west by rotating the subduction zone away from the original strike of the EMNT as a baseline in the CW direction about a vertex, or pole, on the coast of Apulia, Italy. A triangle was formed of the base line, the subduction line, and a chord across the arc of the subtended angle. Currently the vertex opposite the base line does not extend as far as the chord. The east leg curves, shortening the west leg. The curvature demonstrates that the east leg is not as rigid as the west. Plate consumption varies slightly over the west leg but falls off sharply over the east. It is hypothesized that the consumption on the east is expressed by short segments cutting across the scarps, which nevertheless have slip vectors aligned with the western vectors over the entire arc in a wheel-spoke pattern; that is, the azimuths of the vectors decrease regularly from west to east. Though often shown crossing the Adriatic on maps, the subduction does not actually do so. The stress of the rotation was too great for the rock. The subducting plate broke along the KTF and also along the Plato-Strabo trench area, forming a parallelogram that slipped outward between the two strike-slip cross-faults. More than one fault was required to release the stress to the east because the velocity of the rotating subduction increases outward along the radius of rotation. Subduction zone structure The western trough The surface expression of the KFZ appears to come to an end on the west at . It is generally sgreed that the fault represents the offsetting of the Hellenic Arc from the Hellenides north of the Gulf of Corinth due to Aegean Plate extension. Prior to the offset, the subduction zone of the Adriatic, or Apulian, Plate under the edge of the Balkans was continuous
