Additional file 1 of Geological structures controlled the rupture process of the 2011 M9.0 Tohoku-Oki earthquake in the Northeast Japan Arc

Additional file 1. The details of the stratigraphy and geological structure are described in additional file 1 using regional stratigraphic chart (Figure S1), time contour map of the surrounding oceans of the NE Japan arc (Figure S2), typical seismic sections (Figure S3A and S3B), and schematic cross section of the NE Japan arc (Figure S4). The fault movement history of large NW-SE trending transcurrent faults is summarized in Figure S5. The details of lateral displacement, total length, maximum cross-strike width, and tectonic history of each transcurrent fault are described in Section 3 in the additional file 1. Figure S6 shows that the southern margin of the dense distribution of earthquakes for the 80 years period proceding the 2011 Tohoku-Oki earthquake was limited by Faults N to T. The coseismic slip in Block B may have occurred after those in Blocks C to D at the 2011 Tohoku-Oki earthquake (Figure S7). And, Figure S8 shows the relationship between the large transcurrent faults and the back slip rate distribution.
