Fig. 2.

(a) V s perturbation at a depth 40 km (Nakajima et al., 2001). Triangles denote volcanoes. The focal area of the 2008 Iwate-Miyagi earthquake is indicated by the open red rectangule. (b) Vertical cross section of V s perturbation along A–A′. White circles denote hypocenters (1997–1999, all magnitudes, within 0.125 degrees from the cross section). Thick lines denote the Conrad, Moho discontinuities and upper surface of the subducting Pacific Plate, respectively. The bold red line denotes the possible fault plane of the 2008 Iwate-Miyagi earthquake.
