SC-ratio profiles. (a) Same as Fig. 5(b). Six lines crossing east to west are the profile line of (b). (b) SC-ratio profile between 139.5°E and 141.5°E crossing 39.5°N (A–A′), 39.2°N (B–B′), 38.9°N (C–C′), 38.6°N (D–D′), 38.3°N (E–E′), and 38.0°N (F–F′). Shadow areas correspond to the OBR strain concentration zone.
