Table 2 Contraction rate and strain rate of the PHS slab beneath central Japan. The zone numbers represent the area bounded by the colored lines (e.g., the zone 4–5 is the area bounded by the green and red lines). The numbers in parentheses represent the cases with a tear beneath the Kii strait. (a) CAMP model, (b) Hirose model
