Fig. 1

Map of the focal area of the 2011 Tohoku-Oki earthquake. Focal mechanisms represent the mainshock (red), the aftershock in the off-Ibaraki (blue, hereafter “Ibaraki-Oki EQ”), and the aftershock in the off Iwate (green, hereafter “Iwate-Oki EQ”) estimated by NIED. Red squares denote the GEONET sites used for the primary analysis. Blue squares are the additional sites used for the analysis of the Iwate-Oki EQ. Gray rectangles show the assumed fault planes. Black and gray dotted lines indicate trench axis and the depth of the plate interface, respectively. Two red arrows in the bottom right corner indicate the direction of the assumed slip basis, which are oriented 25° from plate subduction denoted by the black arrow. Black squares indicate subfaults that are described in the following figure
