P-wave velocity structure in and around the source area of the 2003 M 7.3 Miyagi–Oki intraslab earthquake. P-wave velocity perturbations are plotted based on the color scale at the bottom for a, c N–S and b, d E–W vertical cross-sections along lines shown in the inset map. White dots in a and b are aftershocks of the M 7.3 event, and those in c and d are background seismicity. Hypocenter of the M 7.3 event is indicated by a star. Thick curves are the Moho of the upper plate and the top surface of the subducting Pacific slab, in order from the top. (After Mishra and Zhao, 2004)
