Fig. 2From: Why do aftershocks occur? Relationship between mainshock rupture and aftershock sequence based on highly resolved hypocenter and focal mechanism distributionsHypocenter distribution of the aftershocks determined by the DD method. The depth of the hypocenter is indicated by the color scale. a Epicentral distribution, b depth distribution projected onto line A–B in (a), and (c) magnified image of the northern part of the aftershock region. Earthquakes within a distance of 6 km from the line are projected in (b). The orange contours projected on line A–B in (b) indicate areas of large slip exceeding a dislocation of 2.0 m as estimated by Iwata and Sekiguchi (2002). The northern part of the aftershock region is indicated by the area enclosed by the broken line in (a)Back to article page
