(a) Map of relocated earthquake hypocenters (scaled according to earthquake magnitude and color coded with depth) within the area outlined by the blue rectangle in Fig. 1(b). (b) Depth sections of relocated earthquakes in each box shown in Fig. 2(a). The strike of the cross section is W25S–E25N, an orientation selected to be roughly perpendicular to the strike of the nodal planes of the large events (refer to a moment tensor solution of each event shown using a lower hemisphere projection rotated into the plane of the section). Clear eastward-and westward-dipping alignments of earthquakes are indicated by black arrows.
