From: Coupling coefficient, hierarchical structure, and earthquake cycle for the source area of the 2011 off the Pacific coast of Tohoku earthquake inferred from small repeating earthquake data

Fig. 4.

Schematic figure showing the distribution of the hierarchical structured asperities at Tohoku. The circles show asperities that have internal structures. The arrows indicate aseismic slip. The dashed bold line shows the NE limit of the Philippine Sea plate and the dashed thin line shows the down-dip limit of the interplate earthquake. The area between the down-dip limit and the Japan trench has both seismic and aseismic slip.
